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.

please forgive the question …. only two years in service ? ….. I thought Beko gave two years as a default, is the fridge freezer out of guarantee ?

Terry, Beko warranty is only 12 months so sadly we had no comeback with them. We did contact them to check, explained the situation in the hope of some flexibility but nothing doing! It grieved me to buy another Beko but since it is the only one which promises to work in a garage it was either that or remodel my kitchen to accommodate a fridge freezer!

Hi Washerhelp, You’ve hit the nail on the head here – it is totally unreasonable for an appliance designed for use in the UK and on sale here, to be incapable of operating at temperatures below 16 Deg C when the average temperature for the region is only 11 Deg C. It is definitely NOT fit for purpose in the UK! I’ve e-mailed Consumer Direct with all the details and I’m waiting to hear back from them. This issue has made me so angry its been really good to receive your feedback, help and advice, to give my arguement better structure. Thank you so much!

Nutella 2 replies Very informative website! Thank you for your quick response! Problems with the fridge I bought from Comet have lead me to research the subject. The concern is that my drafty kitchen gets very cold - only 2 Deg C in January this year, brrr! So whether the current fridge is class SN or N won't matter because neither can cope with such low temperatures. I'm looking for a fridge that can cope most of the time, say down to 6 Deg C but I haven't been able to find any capable of operating at less than 10 Deg C. Any suggestions? From your other articles it seems that a larder fridge would be more likely to keep working in low ambient temperatures, rather than one with a 4* ice box / freezer compartment?

Hello Nutella. The issue raised in this article relates to fridge freezers with only one thermostat in the fridge, where if the fridge compartment turns off because the ambient temperature of the room is cold the side effect is that the freezer compartment also stops working and can partially defrost. This is because such an appliance only has one compressor pumping the coolant around and it stops running when the fridge thermostat shuts off.

If you are talking of a fridge unit only, what problems are you experiencing? If it’s class SN it should operate OK down to 10 degrees Centigrade. However, I have to confess I’m unsure why a fridge, who’s sole purpose is to reduce the temperature inside to between 0 and 5 degrees centigrade should stop working if the temperature of the room is between 5 and 10 degrees C.

I can understand the issues at the top end of the temperature range. I can understand it struggling to work in a very hot environment, but I would have thought maintaining an internal temperature of 0 – 5 degrees would be assisted by the outside temperature being say 8 degrees, not hindered.

On the other hand, when the temperature in your kitchen is only 2 degrees then presumably your fridge doesn’t even need to be on. Have you used a fridge thermometer to observe the temperature inside when it is cold in the kitchen?

My article How are fridges and freezers affected by the room temperature? points out that a fridge would normally only stop running if the temperature drops to around only a few degrees. In this situation though I would have thought it wouldn’t be a problem unless it was a fridge freezer with only one thermostat in the fridge because the freezer would then stop working.

Anyone wanting to run a fridge freezer in a garage should ensure it has separate thermostats for the fridge and freezer, or buy separate fridge and freezers to reduce this problem.

Hello Washerhelp, My fridge is Climate Class N but that wasn’t included in the product info in the store, and when complaining to their Store Manager, he confessed he wasn’t aware of it!
As you quite rightly pointed out, the freezer compartment of my fridge defrosts when the fridge cuts out because they share a common thermostat and compressor, although like you, I would have thought that cooler ambient temperatures (but not below 5 Deg C) would help a fridge dissipate heat energy?!
I agree that when the temperature in the kitchen is 5 Deg C or less, I don’t need a fridge BUT I need to keep my food below 5 Deg C when the ambient temperature is higher. According to MET Office data, the AVERAGE temperature for South East England during 2008 was 11 Deg C. Do you know of a Climate Class which goes down to 6 Deg C, or which manufacturers provide fridges that can operate down to 6 Deg C?

@Kevin Boardley
most likely the method is the same I have been successfully using with my two combos. I built a circuit to monitor ambient temperature and turn on a 15W lamp in the fridge (lower) compartment whenever the outside temp falls too low.
If anybody is interested I can build a few more.

Hello needtoknow: Climate class applies to every single refrigeration appliance. It states the temperature range the product is designed to work optimally in. It’s possible the compressor would be affected if temperature drops below the range due to the gasses used.

Washerhelp 1 reply This main specific problem discussed on this article is caused by a single stat controlling a fridge/freezer, but it's possible some of these modern gasses are shaky at "low" temperatures which are relatively high such as 14 C too. I don't know how Beko get theirs to work at much lower temperatures, presumably they still have to use the modern "environmentally friendly" gasses by law.

Hi washerhelp

I know. But from everything I am reading it is not a simple as that. Many are sold as twin stat but specification on ambient temps states 10 degrees c as minimum. Beko are the only brand I have found so far (UK) specifiying ambient operating temps down to -15 degrees c and may of those seem to be single stat!

At the moment I am still bit skeptical and not a little confused as to wether this is wholly an ambient temperature rating issue or a twin/single thermostat issue, or a bit of both!

I am really wishing that someone could help clear that up for me. But nothing I read anywhere is giving a clear definitive guide on this.

Kevin Boardley 1 reply Don't know if anyone has mentioned this here because there it just too much to read most of it saying exactly the same thing but... John Lewis salesman explained to me that in addition to the thermostat issue (one or two) since the gases used in the compressor have been changed to comply with new regulations to prevent global warming on disposal, the gases that are now used are better for the environment but are not capable of working at lower temperatures. This maybe why, if you are old enough, this whole concept of a fridge freezer not working in colder weather is a relatively new one. It was a new one on me!!

Likely replying to Romeo Sarra

Romeo, I completely agree with you and have covered this in previous comments. How can they sell a fridge freezer, which defrosts the freezer when the temperature of the kitchen gets below 16 C? In winter, many kitchens can easily drop below 16 degrees. I certainly don’t keep the heating on all night. Apart from the cost, we wouldn’t want the noise of the radiators and floorboards creaking as it heats up and cools down and the noise circulation pump running.

As you say this is not a garage, which is more of a grey area, this is in a kitchen. If your appliance is not working properly in your kitchen, specifically because you don’t keep your heating on 24/7 then I would say the appliance is not fit for purpose. Under the Sale of Goods Act it’s the retailer who is responsible and not the manufacturer so don’t waste your time on them.

Beko make fridge freezers that they claim will work down to well below 0 degrees and I’m sure there are other fridge freezers which have separate thermostats for the fridge and the freezer so this doesn’t happen.

Retailers need to find out which of their fridge freezers have this stupid design flaw, which causes the freezer to stop maintaining temperature when the fridge thermostat has switched off, and stop selling them or advise customers about this ridiculous anomaly. A minimum temperature of 16 degrees or else the freezer starts to defrost should not be acceptable in a country that has periodic very cold weather. It may well be that a very well insulated house may not get too cold during the night but clearly there are going to be plenty of houses (especially old or rural ones) where temperatures do get pretty cold during the night in cold winters so people should be advised not to buy one of these appliances.

I’ve just checked my own house. I have a detached house with modern loft insulation and cavity wall insulation. The temperature outside is currently 9 degrees C and the temperature in our hallway is 17.5 C and we have the heating on (admittedly only low). Therefore it’s likely that during the night in winter the temperature in my kitchen would easily fall below 16 C. This means any fridge freezer that would have a problem with that is clearly not fit for purpose!

That's risky - the water pipes and the loos might freeze up. Most central heating systems have a "frost" setting, which should also take care of the fridge. Again, it is only the thermostat (whatever) that needs to be kept warm, in order to keep the fridge working. Perhaps they should run down their deep-freeze before going on holiday ?

Hi Robin: I’d normally agree with your caveat but people are completely unaware of this design problem until they’ve already bought the appliance.

Re the heating system my in-laws don’t have an affected appliance but they should leave the heating on to maintain temperature of at least 7- 10 degrees in my opinion. There are probably still people without central heating though..

@Robin Clay…

Putting a light bulb near the ambient sensor? Domestic refrigerators don’t have an ambient sensor. The only thermo sensors on domestic appliances are inside the refrigerator to control the compressor switching on and off and connected to the compressor, which cuts the compressor off if it gets too hot.

@Paul… Yes it sounds like your problem is the low ambient temperatures, but it might be worth checking the climate rating of your refrigerator.

It seems to me that by reading this thread, no one seems to know exactly how a fridgefreezer works. I will try my best to explain it in the most simple terms, if at any point you don’t understand what I’ve said please post and I’ll try to explain it in better English. Being a refrigeration and air conditioning technician I didn’t really listen in my english classes.

So basically, there is a thermostat in the fridge part of your fridge freezer, because this is what you control most put of the two, when that is set to a certain temp, the refrigeration cycle will try to keep the *fridge* part at that temperature. So when the fridge rises slightly in temp, the compressor will start, pumping refrigerant through the condenser and to the evaporator in the *freezer* first, the refrigerant picks up heat from the freezer and moves to the *fridge* evaporator. The refrigerant is warmer in the fridge evaporator because it is not trying to get the fridge to the same low temps as the freezer. From the *fridge* evaporator it then goes back to the compressor and the cycle starts again. Once the *fridge* is down to temperature the compressor will cut off and stop cooling both the fridge and the freezer.

The reason you are having problems with your fridge freezer in the garage is because when the ambient temperatures drop below freezing, the *fridge* temperature will stay low as well, therefore the compressor will not start. However, this means that the freezer does not get any cooling either, hence why your freezers are defrosting.

There is nothing wrong with your fridge freezer if it does this, apart from the fact that the food in your freezer won’t be frozen, this is just what happens to fridge freezers in sub zero temperatures.

My advice is, if you are going to put a fridge freezer in your garage, get one that has designed working ambient temperatures that the fridge freezer will be working in, in your garage.

Any questions or comments please post
