You open your fridge and the milk is warm. The leftovers don’t feel cold. Your ice cream in the freezer is starting to soften. It’s a sinking feeling — especially if it’s a hot summer day in Barrie or you’ve just done a big grocery run.
Before you panic, take a breath. Many refrigerator cooling problems have simple causes that you can check yourself — and some can be fixed in minutes without spending a dollar.
At AFIXSERVICE, we’ve been repairing refrigerators across Barrie, Innisfil, Collingwood, and Simcoe County for years. Here are the five most common reasons a fridge stops cooling — and what to do about each one.
Check 1: Is the Temperature Setting Correct?
It sounds almost too obvious, but you’d be surprised how often this is the culprit — especially if you have kids in the house or recently moved things around inside the fridge.
What to do:
- Check the temperature dial or digital display
- Your fridge should be set between 1°C and 4°C (34°F–39°F)
- Your freezer should be at -18°C (0°F)
- If the dial got bumped to a warmer setting, just correct it and give the fridge 24 hours to stabilize
Also check: did someone accidentally hit the “vacation mode” or “cooling off” setting? Some modern fridges have these features that reduce or stop cooling entirely.
Check 2: Are the Condenser Coils Dirty?
The condenser coils are located on the back or underneath your fridge. Their job is to release heat from the refrigerant — if they’re coated in dust and pet hair, they can’t do that job effectively, and your fridge struggles to maintain temperature.
What to do:
- Unplug the fridge
- Pull it away from the wall (or remove the kick plate at the bottom front)
- Use a vacuum with a brush attachment or a refrigerator coil brush to gently clean the coils
- Plug it back in and wait a few hours
This simple maintenance task — which most people never do — can dramatically improve cooling performance. Clean the coils at least once a year, twice if you have pets.
Check 3: Are the Door Seals (Gaskets) Intact?
The rubber gaskets around your fridge and freezer doors create an airtight seal. If they’re torn, warped, or have gaps, warm air leaks in constantly — and your fridge can never get cold enough.
The dollar bill test: Close the fridge door on a dollar bill. If you can pull it out easily with no resistance, the seal isn’t tight enough in that spot.
What to do:
- Inspect the full perimeter of both doors
- Look for cracks, tears, or areas where the gasket pulls away from the door frame
- Clean the gaskets with warm soapy water — sometimes a dirty gasket doesn’t seal well even if it’s not damaged
- If the gasket is torn or deformed, it needs to be replaced (this is a common, affordable repair)
Check 4: Is There Enough Space Around the Fridge for Airflow?
Your refrigerator needs air circulation around it to release heat from the condenser. If it’s crammed tightly into a cabinet with no clearance, it will run hot and inefficiently.
Recommended clearances:
- Back: at least 2–5 cm (1–2 inches)
- Sides: at least 2 cm on each side
- Top: at least 15 cm (6 inches)
Also check: don’t block the vents inside the fridge. Overpacking or pushing food against the back wall can block cold air circulation inside the unit.
Check 5: Is the Evaporator Fan Running?
The evaporator fan is inside the freezer section. It circulates cold air from the freezer into the fridge compartment. If this fan fails, the freezer might stay cold while the fridge section warms up — a very common complaint.
How to check:
- Open the freezer and listen — you should hear the fan running
- If the freezer is cold but the fridge is warm, the evaporator fan is the likely culprit
- Also check: is there heavy ice buildup around the freezer vent or back wall? A frost/ice blockage can stop the fan from circulating air
If you hear the fan but it’s making a loud grinding or whirring noise, the fan motor is failing and needs to be replaced before it stops completely.
When to Stop DIY and Call a Professional
If you’ve checked all five things above and your fridge still isn’t cooling, the issue is likely one of these more complex problems that require a certified technician:
- Compressor failure — when it fails, the fridge won’t cool at all
- Refrigerant leak — requires specialized equipment and is regulated in Canada
- Defrost system failure — a faulty defrost timer, heater, or thermostat can cause ice build-up that blocks cooling
- Control board issues — especially common on newer “smart” refrigerators
