Who repairs a freezer that stopped freezing in Toronto? N Appliance Repair does. Call (437) 524-1053, available 7 days a week. Serving Toronto since 2017, our technicians cover North York, Scarborough, Etobicoke, and Mississauga — when your freezer fails, every hour matters for the food inside, and we prioritize same-day response for freezer calls.
Quick Answer: A freezer that runs but does not freeze is usually caused by a failed evaporator fan motor, a blocked defrost system, or dirty condenser coils. Call (437) 524-1053 immediately — frozen food can begin to thaw within 4 hours of a freezer failure.
Why Is My Freezer Not Cold Enough?
A freezer that hums but fails to maintain freezing temperatures has one of several problems. The refrigeration cycle requires cold air to circulate from the evaporator coils through the freezer compartment. If any component in that chain fails, temperatures rise even while the compressor continues to run.
The most common causes our Toronto technicians encounter, in order of frequency:
- Evaporator fan motor failure: The fan that circulates cold air from the coils stops working. The coils remain cold, but heat from food and door openings is not removed.
- Defrost system failure: The defrost heater or defrost thermostat fails, causing ice to build up on the evaporator coils over several weeks until airflow is completely blocked. The freezer runs constantly but cannot get cold.
- Dirty or blocked condenser coils: Dust accumulation on the condenser coils (usually underneath or at the back) prevents the refrigerant from releasing heat, causing the system to overheat and underperform.
- Failed start relay: A small electrical component that helps start the compressor. When it fails, the compressor may not run at all or may run only intermittently.
- Door gasket failure: A worn seal allows warm air to constantly enter, overwhelming the cooling system — especially common in garage-stored chest freezers in Toronto's summer heat.
How Do I Know If It Is the Defrost System?
Defrost system failures follow a predictable pattern. The freezer works perfectly for 2–4 weeks, then gradually loses cooling performance over the next 1–2 weeks as ice builds up on the coils. If you manually defrost the unit (unplug it for 24–48 hours with the door open), it will work fine again — but only until frost builds up again. This cycle repeating is the clearest sign of a defrost heater or defrost thermostat failure. Alex M., our lead technician, calls this the "frost cycle test" and uses it as a first-visit diagnostic on every freezer that's gradually losing cooling.

All repairs come with a 90-day warranty. We service standalone chest freezers, upright freezers, and the freezer compartment of combination fridge-freezers.
How to Check Your Freezer Before Calling
Check the temperature setting
Confirm the thermostat dial or digital control is set to at least -18°C (0°F). This occasionally gets accidentally bumped — especially in chest freezers.
Check the condenser coils
Pull the unit away from the wall. If you see a thick layer of dust on coils or on the grille underneath, clean them with a vacuum and coil brush. This alone can restore performance.
Listen for the evaporator fan
Open the freezer door and press the door switch manually (the switch that turns off the interior light when you close the door). You should hear the evaporator fan running. No fan sound = likely fan motor failure.
Check the door seal
Run your hand around the door perimeter while the freezer is running. Any cold air escaping at the edges indicates a compromised gasket that needs replacing.
Food Safety Warning: A fully stocked freezer will keep food safe for approximately 24–48 hours after failure if the door stays closed. A half-full freezer stays safe for about 24 hours. If you are unsure how long the freezer has been warm, use a thermometer — discard anything that has been above -4°C for more than 2 hours.
Should I Repair or Replace My Freezer?
Chest freezers and upright freezers have long service lives — 15 to 20 years for a well-maintained chest freezer. If your unit is under 12 years old and the repair cost is under $250 CAD, repair is almost always the right call. Units over 15 years old with compressor or sealed system issues are candidates for replacement. Our technicians will give you a straight answer about which path makes sense for your specific unit and situation.
