Why is my refrigerator not cooling?
A fridge that runs but does not cool almost always has a blocked airflow path, a failed defrost component or a dying compressor. Start with the condenser coils and the evaporator fan: on the units we see across Toronto, those two account for most no-cooling calls, and both are same-visit repairs.
Likely causes
- Condenser coils packed with dust — the single most common cause, and the cheapest to fix
- Evaporator fan motor seized, so cold air never reaches the fresh food section
- Defrost heater or thermostat failed, letting ice seal the evaporator solid
- Start relay or capacitor gone, leaving the compressor humming without running
- Sealed system leak — the expensive one, and the reason we test before quoting
What we do
We check the temperature at the evaporator, listen to the compressor under load, and measure current draw before touching a part. That order matters: swapping a start relay on a fridge with a refrigerant leak wastes your money and our time. You get the diagnosis and the number before anything is replaced.
What affects the cost
Coil cleaning and fan motors sit at the low end. Sealed-system work is the expensive end, and on a fridge past ten years we will tell you honestly when replacement wins.
