Can you put a fridge freezer in a garage?

💡

Quick Answer

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

+10°C
Minimum ambient temperature most standard UK fridge-freezers are rated to work in (climate class SN)
0 to +5°C
Target temperature inside the fridge compartment
-18°C
Target temperature inside the freezer compartment
~0 to +4°C
Ambient threshold below which the single thermostat shuts off in a combined unit

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:

Garage temperature drops below 4°C

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 compartment reaches target temperature passively

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.

The compressor stops – the freezer no longer receives active cooling

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.

Freezer temperature rises – food begins to defrost

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.

Partial defrost – possibly unnoticed

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 the defrost is not garage-related

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.

Whitegoodshelp (Andy Trigg) 0 replies Unfortunately a shed is a bad place to keep a fridge or fridge freezer. In winter or summer it will see extremes of temperature causing different problems. The answer depends on whether this should be common knowledge, or obvious or not. Many people buy refrigeration appliances to put in a garage, which can cause problems in winter as discussed at length in this article and comments. I believe sales staff should always ask where one is going to be sited because they are very much aware of this problem. So if it were in a garage I would be more inclined to fight the charge but to be honest I think most people would wonder if a hut is suitable, if only because it's forced to get extremely hot in summer. I've heard of, and even visited many cases of fridge freezers failing inside garages and never known anyone be charged for it so I suspect they may be trying to charge you because they think it should be more obvious it's not a suitable place for one. You would need to seek consumer advice from Citizens Advice to see what they think but I don;t think retailers have any legal requirements to enquire how people are going to use products they sell. It's merely a moral and practical requirement.

Many thanks for your advice Andy

Whitegoodshelp (Andy Trigg) 0 replies Helo Stace. People at various manufacturers do read my sites, whether they ever take any notice of anything is another matter though :) Your comment highlights how poor product advice is at some of the big retailers. I would go to a John Lewis store if possible and ask them. I would suggest you look at a good quality fridge-freezer. Proline and Beko are both budget appliances and made to sell cheap. If you have a good quality one with good insulation, and 2 stats to separately control the fridge and the freezer you may not have any problems.

Stace 0 replies I'm looking for a new fridge freezer (FF) now as my current proline (6 years old) is on the blink. I never knew about climate class until looking this time round for a new FF. Current one is a N class. As my property is single glazed in the winter months the room can dropped to about 12oc. No way am i spending more to have a thermostate heater in here just for the FF!. Its difficult looking out for a SN class (down to 10oC) and most seem to be N or ST class. As it happens I was in Currys and the young lady assistant didn't know what climate class was although she was in the FF section. Also annoying if you go into the stores they dont have the booklet so you cannot read the specifications and of course you cannot see the rating plate as its no doubt at the back of the FF where you cannot access it. I originally disgarded looking at BEKO due to the fire safety of their older FF but maybe there are ok now?? who knows. Other option if I need up buying a N class and do find out I have issues this coming winter I know that someone on the thread suggested putting on roof insulation on the sides - wonder if this would help? would it? ... but there there is the issue are ensuring that there is space around the FF for circulation as per the usual manual. Looking at the FF on the internet it is so annoying when finding out its another N class and not SN. Also though... the BUSH FF via Argos they state they go down to 10oC but when reading a Q&A on the actual model - a lady asked if she could put it in her conservatory - the response from Argos was....sorry that was a mistake and that the FF Ambient temp is 16oc so you cannot even rely on the full specifications listed on the internet. .. but any comments re the roof insulation covering on the side of the FF (fridge part only) - or is that just stupid and wouldn't work. Shame no manufacturers read this website and in particular this thread.

Ronnie 0 replies I purchased a Curry's own make fridge freezer (Curry's ESS CE55CW12) in September last year and put it in my garage. During the first very cold spell of weather we had in the winter the freezer part of the appliance defrosted and I threw the contents away. A friend told me of the possible cause and I looked at this website. I paid a visit to the Curry's store and commented that I should have been advised that the appliance was not suitable for putting in a garage as it had only one thermostatic control. The salesperson told me that they do not stock any fridge freezers with dual control. Curry's are therefore lunlikely to advise potential customers of the hazards of putting a fridge freezer in a garage or their sales will drop drastically. I only wanted a freezer but decided to go for the fridge/freezer as sometimes extra fridge space is useful. I can use the whole appliance as a freezer now if I put the dial up to 6 (max) but if the temperature drops drastically again it may stop working again

Andy Trigg 0 replies That's right Eric, the new gasses can be explosive too. Seen cases of fridges blowing up and throwing the door across the kitchen. Ridiculous.

Eric 0 replies I was told that the refrigerant agent in old fridges and freezers is no longer acceptable under EU rules. It has been changed to a more easily recyclable liquid / gas. The old refrigerant was capable of operating down to a much lower temperature that the modern 'green' refrigerant. If you own an old fridge freezer HANG ON TO IT.

Washerhelp 0 replies I would never buy a freezer or fridge freezer without a defrost warning Anonymous. Partially defrosted food can become dangerous if refrozen so I would expect all decent modern appliances would have one. Some sort of audible alarm, flashing warning or red light is needed to warn that the freezer's temperature has been compromised.
