Can You Lay a Fridge or Freezer on Its Side or Back When Moving It?
Fridges and freezers should always be transported upright. If this is genuinely impossible, they can be laid on one specific side, but never on their back or front. After laying one down, you must leave it standing upright for several hours before switching it on. Failure to do so can cause permanent compressor damage.
Moving a fridge or freezer requires more care than most other household appliances. The short answer is: always keep it upright if you possibly can. If you must lay it down, there is a right way and a wrong way, and getting it wrong can permanently damage the appliance. This guide covers the safe way to move, lay down, and bring back into service a fridge or freezer.
Why does the position matter when moving a fridge?
The risk is not to the outer casing – it is to the sealed refrigeration system inside. Every fridge and freezer has a compressor that contains oil and refrigerant. When the appliance is kept upright, the oil stays exactly where it should be.
When it is laid down incorrectly, compressor oil can flow into the cooling pipes. Switching the appliance on before this oil has drained back can cause serious damage.
Restricted or blocked refrigerant flow, poor cooling performance, compressor damage due to lack of lubrication, and in some cases permanent failure of the appliance.
What is the safest way to transport a fridge or freezer?
This is the only method that carries no risk to the refrigeration system.
In practical terms:
- Use a sack truck or appliance trolley to move and transport it vertically.
- Secure it properly in the vehicle so it cannot tip or fall during transit.
- Avoid rough roads, sharp braking, or unnecessary vibration where possible.
- Empty the contents and defrost the appliance before moving.
- Secure internal shelves and drawers so they do not shift during transit.
What if you have no choice but to lay it down?
In some situations such as limited vehicle height, it may not be possible to transport the appliance upright. If this is unavoidable, there are strict rules about how to do it safely.
You can lay it on its side
But only on the correct side, determined by the position of the compressor pipes at the back of the appliance (see below).
Never lay it on its back or front
Laying it on its back or front forces oil directly into critical parts of the system and significantly increases the risk of permanent damage.
Which side should a fridge or freezer be laid on?
The correct side depends on the position of the compressor pipes at the back of the appliance. Look at the rear panel – you will see pipes connected to the compressor. One pipe is usually larger and carries refrigerant into the cabinet.
The pipe that leaves the compressor and runs into the cabinet must face upwards during transport. This helps prevent oil from flowing into the cooling system where it can cause blockages.
In simple terms: look at the back of the appliance, identify which side the main compressor pipe runs up towards the cabinet, and lay the appliance down so that pipe faces the ceiling, not the floor.
If the appliance is laid on the wrong side, oil can enter the pipework and remain there even after the appliance is stood upright again, which is why the waiting period before switching on is so important.
What should you do before and after the move?
Before moving
-
Unplug the appliance well in advance, ideally several hours before moving, to allow it to reach room temperature.
-
Empty all contents completely. Do not attempt to move a fridge or freezer with food or drink inside.
-
Defrost if necessary. Ice build-up adds weight and can cause water damage during transit.
-
Secure internal components. Remove or tape down shelves, drawers, and door compartments so they cannot shift.
After moving: how long before you switch it on?
This is one of the most important steps and the one most commonly overlooked.
| How it was transported | Recommended waiting time |
|---|---|
| Upright throughout | 30 minutes to 1 hour is sufficient in most cases |
| Tilted briefly during moving | At least 1 to 2 hours standing upright before switching on |
| Laid on its side for transport | At least 4 hours, ideally up to 24 hours, standing upright |
When in doubt, wait longer rather than shorter. The waiting time allows displaced oil and refrigerant to drain back into their correct positions within the compressor. Switching on too early is the most common cause of post-move compressor damage.
Why is manufacturer guidance so inconsistent?
Many manufacturer manuals provide vague or limited guidance on this topic. Some simply advise “leave the appliance to stand before switching on” without clearly explaining why, or how long is needed.
This variation reflects different appliance designs and different risk tolerances between manufacturers. Unfortunately, it can give the impression that any transport position is acceptable, which is not the case. When in doubt, always treat the appliance as if it has been laid down and wait the full recommended period before switching on.
Frequently asked questions about moving a fridge or freezer
Can I transport a fridge freezer on its back?
No. Laying a fridge or freezer on its back is one of the most damaging things you can do during transport. It forces compressor oil into the cooling pipes, significantly increasing the risk of compressor failure. If you cannot transport it upright, it must be laid on the correct side only, never on its back or front.
How do I find which side to lay my fridge on?
Look at the back of the appliance. You will see pipes connected to the compressor at the bottom rear. Identify the pipe that runs from the compressor up into the cabinet – this pipe must face upwards when the appliance is laid down. If you are unsure, it is safer to keep the appliance upright or wait and seek advice before transporting it.
I laid my fridge on its back by mistake. What should I do?
Stand the appliance upright immediately and leave it for at least 24 hours before switching it on. The longer you leave it, the better the chance that the oil will drain back into the compressor correctly. Do not be tempted to switch it on early to check if it is working – this is the most common cause of permanent post-move damage.
How long should I leave a fridge before turning it on after moving?
If transported upright: 30 minutes to 1 hour is usually sufficient. If it was tilted during moving: wait at least 1 to 2 hours. If it was laid on its side: wait at least 4 hours, and ideally up to 24 hours. When in doubt, always err on the side of waiting longer.
My fridge is not cooling properly after being moved. What should I do?
First, check how long you left it before switching on. If it was less than the recommended time, switch it off again and leave it standing for the full period before trying again. If it still does not cool correctly after the full waiting period, the compressor may have been damaged during transit. See our fridge freezer help section for further fault guidance, or book a qualified engineer.
Does the same apply to American-style fridge freezers?
Yes. The same principles apply to all fridge freezers, including American-style models. These are often larger and heavier, which can make upright transport more difficult. However, the risk of oil contamination is the same, and the correct side and waiting time rules must still be followed. Read our guide to delivering American-style fridge freezers for more specific advice.
Does the manufacturer guarantee cover compressor damage from moving?
Generally no. Manufacturer guarantees and warranties cover faults caused by manufacturing defects, not damage caused by transport, installation, or handling by the customer. If compressor failure occurs after a move and the appliance was previously working correctly, the cause is usually attributed to transport handling rather than a manufacturing fault. For best protection, use a professional appliance delivery or moving service that includes transit cover, particularly for large or expensive appliances.
Need help with a fridge freezer fault after moving?
If your appliance is not cooling correctly after being moved, our engineers can help diagnose the problem and arrange a repair.
After laying a fridge or freezer on its side, always leave it standing upright for at least 4 hours, ideally 24 hours, before switching on.
How are fridges and freezers affected by the room temperature?
Most refrigeration appliances sold in the UK are rated to operate between 10 degrees and 32 degrees Celsius. In a cold garage or outbuilding where temperatures fall below 10 degrees in winter, a combined fridge-freezer may work incorrectly – and in some cases the freezer section can partially defrost. Separate fridges and standalone freezers are less susceptible to this problem. Some appliances are now specifically designed for colder environments.
Climate class is the manufacturer’s specification for the ambient temperature range in which a refrigeration appliance is designed to work reliably. Understanding this prevents choosing the wrong appliance for a garage, shed, or cellar installation – and explains problems that are already occurring.
What Is Climate Class?
All refrigeration appliances carry a climate class rating that specifies the minimum and maximum ambient (room) temperature they are designed to operate in. See our guide on climate classes for fridges, freezers and fridge-freezers for the full classification system.
The most common climate class for UK domestic appliances is SN-ST, which covers a range of approximately 10 degrees to 38 degrees Celsius. In a typical UK home, this range is easy to stay within. In a garage, shed, or cellar, temperatures in winter may regularly fall below 10 degrees – and in summer an uninsulated garage can exceed 35 degrees.
What Happens When the Temperature Is Too Cold
A combined fridge-freezer with a single thermostat – which is the majority of domestic fridge-freezers – is particularly vulnerable to cold ambient temperatures. Here is why:
How a single-thermostat fridge-freezer works
A combined fridge-freezer typically has one compressor and one thermostat, which is usually located in the fridge compartment. The thermostat cycles the compressor on and off to maintain the fridge at 0 to 5 degrees. The freezer section, needing to reach minus 18 degrees, is kept cold by the same compressor running continuously enough to also cool the freezer.
The cold garage problem
When the ambient temperature in the garage falls to 10 degrees or below, the fridge compartment can reach its target temperature from the surrounding air alone – without the compressor needing to run. The thermostat shuts off. With the compressor off, the freezer section is no longer actively cooled. If the thermostat stays off for an extended period, the freezer compartment gradually warms up and food can begin to partially defrost.
The hidden partial defrost risk
In some cases food partially defrosts and then refreezes when the compressor resumes – creating a cycle the owner may not notice. Food that has been repeatedly partially defrosted and refrozen has reduced quality and shorter safe storage life. Ice cream is often the first item to show obvious changes – becoming coarse and crystallised.
Some have separate temperature controls for each compartment. If a fridge-freezer is already installed in a cold space and the freezer is struggling, check the specification to confirm whether it has a single thermostat or independent controls for each section.
What Happens When the Temperature Is Too Hot
If the ambient temperature rises above the appliance’s maximum climate class rating, the condenser (typically at the back of the unit) cannot shed heat effectively. The condenser needs the surrounding air to be at least 10 degrees cooler than the condenser itself for heat to radiate away. In a very hot garage in summer, this differential cannot be maintained.
The consequences are the opposite to cold ambient temperature problems: the appliance runs continuously trying to maintain the internal temperature, uses significantly more energy, and may struggle to keep food cold. Prolonged operation above the rated maximum temperature can cause the compressor to overheat and fail.
Separate Fridge and Freezer vs Combined Unit
Separate fridge and standalone freezer
- Each appliance has its own thermostat controlling only its own compartment
- A standalone freezer will continue to maintain temperature correctly in cold ambient conditions because its thermostat is set to reach minus 18 degrees – the ambient temperature being cold does not prevent the thermostat from cycling
- Generally more suitable for garage installation than combined units
Combined fridge-freezer (single thermostat)
- Single thermostat in the fridge section controls the whole appliance
- In cold conditions, the thermostat can shut off the compressor entirely while the fridge is kept cool by the ambient air
- The freezer section is not maintained independently and can defrost
- More susceptible to both cold and hot ambient temperature extremes
Appliances Designed for Cold Environments
Some manufacturers now produce refrigeration appliances specifically rated for cold environments – with climate classes that extend down to minus 15 degrees Celsius or similar. These are sometimes marketed as “garage ready” or “outbuilding rated.” If placing a fridge or freezer in a garage or outbuilding is a firm requirement, searching specifically for appliances with an appropriate low-temperature climate class rating is strongly recommended over fitting a standard domestic appliance.
Condensation in Cold Rooms
A refrigerator or freezer in a cold, damp garage can develop condensation on the external cabinet surfaces – particularly on the warmer parts of the outside wall. This can lead to mould growth on the door seal and rust on the cabinet over time.
Continuous condensation on specific patches of the cabinet even when the room is not particularly cold can indicate insulation breakdown – where the insulation inside the cabinet wall has failed. This causes cold air to leak from the cabinet continuously, the appliance to run excessively, and increased energy use. Insulation failure is generally terminal for the appliance.

Frequently Asked Questions
Can I put a fridge-freezer in a garage?
It depends on the temperature range the garage reaches and the climate class rating of the appliance. Most UK domestic fridge-freezers are rated to a minimum of 10 degrees Celsius. If the garage regularly falls below this in winter, a combined fridge-freezer with a single thermostat may cause the freezer section to defrost. Standalone freezers are less susceptible. Some appliances are now specifically rated for cold environments – these are better suited to garage installation.
Why is my garage fridge-freezer defrosting in winter?
Almost certainly because the ambient temperature in the garage has fallen below the appliance’s minimum climate class rating, causing the single thermostat to shut off the compressor. With the compressor off, the freezer section is no longer actively cooled and gradually warms up. This is a design characteristic of combined fridge-freezers with a single thermostat in the fridge section, not a fault with the appliance. A separate standalone freezer does not have this problem as its thermostat controls the freezer independently.
Is a standalone freezer safe in a cold garage?
Generally yes, as long as the ambient temperature stays within the appliance’s climate class range. A standalone freezer has its own thermostat set to maintain minus 18 degrees. Cold ambient temperature does not cause it to shut off in the way that affects a combined fridge-freezer, because minus 18 degrees is far colder than any UK garage temperature. Some freezers are specifically rated for very cold environments – check the climate class if the garage regularly falls below 5 to 10 degrees.
Can you put a fridge freezer in a garage?
If a combined fridge-freezer in a cold garage is defrosting in winter, the most likely cause is not a fault – it is that the fridge-freezer has a single thermostat in the fridge section that is shutting off because the garage is already cold enough to keep the fridge at temperature. When this happens, the freezer also shuts off and food can begin to defrost. This is a known limitation of single-thermostat combined units, not a covered fault under guarantee.
Thousands of fridge-freezers in UK homes are installed in garages and outbuildings. Most of the time this works fine – but in cold winters, a specific and well-known design limitation in many combined fridge-freezers causes the freezer section to defrost. It is not a fault. It is a consequence of the appliance’s climate class rating and single-thermostat design.
The Key Temperatures to Know

What Happens When the Garage Gets Cold
Combined fridge-freezers with a single thermostat – which is the majority of domestic models – have the thermostat sensor located inside the fridge compartment. This thermostat controls the compressor that cools both compartments. Here is the chain of events that leads to freezer defrost in a cold garage:
The ambient temperature in the garage falls to around 0 to 4 degrees or below. This typically happens on cold winter nights or during extended cold spells.
The fridge section only needs to reach 0 to 5 degrees to satisfy the thermostat. In a 4-degree garage, the cold ambient air achieves this without the compressor needing to run. The thermostat sensor reads “cool enough” and shuts the compressor off.
With one compressor controlled by one thermostat, the freezer section gets no active cooling while the fridge thermostat is satisfied. The freezer compartment begins to warm toward the ambient garage temperature.
Even a garage temperature of 4 to 8 degrees – too cold for humans to notice much – is far warmer than the minus 18 degrees the freezer needs. If the thermostat stays off for several hours or longer, frozen food begins to thaw. Ice cream is usually the first obvious sign.
In milder cold spells the thermostat may cut back in before a complete defrost, causing food to partially thaw and refreeze. The owner may not notice unless the quality change is obvious. Food that has been repeatedly partially defrosted and refrozen has reduced quality and shorter safe storage life.
Which Appliances Are Affected?
Combined fridge-freezers with a single thermostat
The majority of domestic combined fridge-freezers. The thermostat is in the fridge section and controls the entire appliance. These are the units that fail in cold garages as described above. Budget models are more likely to have this design – a second thermostat adds cost.
If you can only set one temperature dial for the whole appliance, it probably has a single thermostat. If separate temperature controls exist for fridge and freezer independently, it likely has two thermostats and is less susceptible to this problem.
Standalone freezers and separate fridges
A standalone freezer has its own thermostat set to reach minus 18 degrees. No UK garage temperature comes close to this – the ambient cold cannot satisfy the freezer thermostat, so the compressor keeps running and the freezer stays frozen. Standalone freezers generally cope well in garages, subject to the general climate class range and condensation considerations.
Can You Claim Under Guarantee?
Almost certainly not. The appliance is installed outside its specified climate class operating range. The manufacturer’s guarantee applies to appliances used as intended – in a temperature-controlled indoor kitchen environment. An engineer attending under guarantee in this situation will typically confirm there is no fault and advise that the installation environment is the cause.
The stronger argument is with the retailer at the point of sale. It is widely known in the trade that a significant proportion of fridge-freezer call-outs involve garage installations in cold weather. A well-advised retailer should ask where the appliance is being installed and advise accordingly. In practice, many do not.
If a combined fridge-freezer defrosted and it was not in a cold garage, or the garage temperature did not drop significantly below 10 degrees, do not assume this article describes the cause. Faults in the defrost heater, thermostat, or sensor can cause the same symptoms for entirely different reasons. See our guides on how frost-free defrosting works and fridge-freezers in garages for further diagnosis.
What Can Be Done?
-
Replace the combined unit with a separate fridge and standalone freezer. The standalone freezer will not suffer this problem. This is the most reliable long-term solution for a cold garage installation. -
Replace with a combined fridge-freezer that has dual thermostats. A unit with separate temperature controls for fridge and freezer sections has independent thermostats. The freezer thermostat will continue to run the compressor regardless of how cold the garage gets. Confirm with the retailer before purchasing. -
Look for a garage-rated appliance. Some manufacturers now produce fridge-freezers specifically rated for cold environments, with climate classes that extend down to minus 15 degrees or lower. Search for “garage-rated fridge-freezer” or confirm the specific climate class rating before buying. -
Keep the garage above 10 degrees. A frost-protection setting on an oil-filled radiator placed in the garage during cold spells would prevent the thermostat shutting off – but this must run continuously during cold periods, which is not always practical or economical.

Frequently Asked Questions
Why is my freezer defrosting in the garage in winter?
If the garage temperature has dropped to around 4 degrees or below, the most likely cause is that the fridge-freezer’s single thermostat has shut the compressor off because the fridge compartment is already cold enough from the ambient air. With the compressor off, the freezer stops receiving active cooling and food begins to defrost. This is a known design limitation of combined fridge-freezers with a single thermostat – it is not a component failure or a covered fault.
Will a chest freezer or standalone freezer work in a cold garage?
Generally yes. A standalone freezer has its own thermostat set to maintain minus 18 degrees. UK garage temperatures never reach minus 18 degrees, so the thermostat keeps calling for cooling regardless of how cold the ambient temperature gets. The compressor continues to run normally. Subject to the general climate class operating range and condensation management, standalone freezers typically work well in UK garages.
Is my food safe after a partial defrost?
Food that has partially defrosted and refrozen may be unsafe to eat depending on what it is and how warm it got and for how long. Meat, fish, and dairy products are most at risk. If food has thawed to a temperature above 5 degrees for more than 2 hours, it should be discarded rather than refrozen. If the defrost was mild and brief and the food is still cold to the core, the safety risk is lower – but when in doubt, throw it out. If the appliance has a temperature alarm and it has triggered, treat all freezer contents as compromised.
