Garage Fridges and Freezers in an Ontario Winter: What You Need to Know

A second fridge in the garage earns its keep in November and December, when the kitchen fridge is packed with holiday food. The trouble starts once the temperature outside drops below freezing and stays there.

Every winter we get calls from homeowners in Kitchener, Waterloo and Guelph whose garage fridge seems to have quit. Most of the time nothing is broken. The fridge is simply sitting somewhere colder than it was designed for.

Why a Cold Garage Confuses a Standard Fridge

Most household refrigerators are built to run in a room that stays roughly between 10°C and 32°C. An unheated Ontario garage falls outside that range for months at a time.

On many fridges, the thermostat sits in the fresh food section. The compressor runs when that section warms up and shuts off once it is cold enough. The freezer is cooled by the same system, so it only gets cold when the fridge side asks for it.

In a cold garage, the fridge side rarely warms up, so the compressor barely runs. The freezer then drifts toward the temperature of the garage. On a mild day around zero, frozen food can soften and start to thaw. Even at minus 10°C, the freezer is well above the minus 18°C it should hold.

In a deep cold snap, the opposite happens: milk and drinks in the fridge section freeze solid.

1. Check the Operating Range

Look up the ambient temperature range in your manual or on the manufacturer's website. If your garage regularly drops below the minimum, the fridge will not behave properly no matter how you set it.

2. Put a Thermometer in Each Section

An inexpensive appliance thermometer tells you what is really going on. The fridge side should sit between 1.5°C and 3°C, and never above 4°C. The freezer should read minus 18°C or colder. Check both on a cold morning and again on a milder afternoon.

3. Do Not Expect the Dial to Fix It

Turning the fridge colder may freeze everything on the fresh food side. Turning it warmer means the compressor runs even less, and the freezer gets warmer still. The setting is not the problem. The location is.

4. Know Why Chest Freezers Behave Differently

A standalone chest or upright freezer reads its own temperature, so it is not fooled the same way. Many handle a cool garage well, but check the rated range before you count on one through January.

5. Look at a Garage-ready Model

Some refrigerators are built specifically for garages and rated for a much wider temperature range. A few manufacturers also offer a heater kit for certain models, which adds a little warmth near the thermostat so the fridge cycles normally. Only use one approved for your exact model.

6. Bring It Inside or Shut It Down for the Season

If you do not need the extra space all winter, unplug the fridge, empty it, wipe it out and prop the doors open so mould and odours do not build up. Otherwise, move it to a heated basement until spring.

Signs It Is More than the Weather

If a fridge still will not hold temperature after you move it somewhere warm, the cold was not the real cause. Watch for a compressor that clicks on and off without running, heavy frost on the back wall of the freezer, or a burning smell. Unplug it and call for service. Anything involving the sealed refrigerant system or electrical components is a job for a technician.
