Let’s be honest — few household problems cause panic quite like opening your fridge and feeling warm air. Food spoils fast, and figuring out what went wrong isn’t always obvious. If your refrigerator not cooling properly is what brought you here, you’re in the right place.
Here at Ottawa Appliance Service, we’ve walked through this exact situation with countless Ottawa homeowners. Most of the time, there’s a clear reason — and often a straightforward fix.
So Why Has Your Refrigerator Stopped Cooling?
A refrigerator not cooling can point to several different problems. Some you can tackle yourself in 20 minutes. Others genuinely need a trained technician. This is what we most frequently see.
1. Condenser Coils Caked with Dust
These coils sit at the back or bottom of your fridge and push heat away from the unit. When they’re buried in dust – which happens gradually over months – your fridge has to work overtime and still can’t keep up.
The fix: Unplug the unit, find the coils, and vacuum them off. It’s quick, free, and worth doing every 6 to 12 months regardless.
2. The Evaporator Fan Has Quit
This fan is responsible for pushing cold air into the fresh food section. When it fails, your freezer might still feel fine while the fridge side slowly warms up. You might also hear strange sounds, or notice the fan blade sitting completely still when the door opens.
This one needs a professional to sort out — replacement parts and the labour involved make it a technician job.
3. Defrost System Breakdown
Your fridge contains a defrosting function to stop ice formation inside the fridge coils. Once that function malfunctions due to failure of either the heating unit, thermostat, or timer, then the whole process is taken over by ice, leading to no airflow. Over a period of days the fridge slowly cools until it stops cooling altogether.
Look out for frost build-up inside the freezer or a refrigerator that doesn’t just stop working, but gets warmer and warmer over time.
4. Door Seals That Have Had Better Days
If your door gaskets are damaged or distorted, there is always going to be warm room air entering. Your fridge will always lose the battle against it. Simple test: Close the door with a piece of paper inside.
5. Fault in the Compressor or the Refrigerant
If all other parts seem to work fine, then there might be a more severe problem. The two main causes of your fridge not cooling are a fault in the compressor or a leak of the refrigerant in your system. Both of these are issues that require professional help.
Run Through This Before You Call Anyone
A few things can help keep you from having to make that service call:
- Does the refrigerator have electricity and is the plug operational?
- Is the thermostat dial set right — around 3°C for the fridge, -18°C for the freezer?
- Is there room behind the refrigerator for proper ventilation?
- Are the condenser coils dirty?
- Are the door seals sitting flush and holding tight?
If after trying everything listed above your refrigerator still doesn’t work, then it’s time to get a professional involved.
