Why your Calgary fridge has stopped cooling
A fridge that's not cooling is a time-sensitive problem — food spoilage begins within 4 hours at room temperature. Understanding the likely cause helps you decide how urgently to act. In Calgary, fridge cooling failures have a few patterns that differ from the national average, largely due to the city's temperature extremes and hard water supply.
Calgary's climate swings from −30°C winter nights to +35°C summer afternoons. Refrigerators in attached garages or against cold exterior walls in Calgary homes are stressed differently than fridges in climate-controlled interiors. We see a higher-than-average rate of garage refrigerator failures in Calgary during winter — most consumer fridges are not rated for ambient temperatures below 10°C, and the compressor can't run efficiently at sub-zero garage temps.
Most common reasons a fridge stops cooling in Calgary
Evaporator fan motor failure
The evaporator fan circulates cold air from the freezer compartment into the fridge section. When it fails, the freezer may still be cold while the fridge warms up — a classic symptom. Evaporator fan failure is among the most common fridge cooling issues we see in Calgary, particularly in Samsung and LG side-by-side models aged 5–8 years. Parts cost: $40–$85. Total with labour: $120–$210.
Defrost system failure — frost buildup
Modern frost-free refrigerators run an automatic defrost cycle every 8–12 hours. If the defrost heater, defrost thermostat, or defrost timer fails, frost accumulates on the evaporator coils until airflow is completely blocked. The fridge warms up gradually over 1–3 days. In Calgary's dry winter air, frost buildup accelerates when door seals are slightly degraded — cold, dry air infiltrates more readily. Manual defrost (unplug the fridge for 24–48 hours with towels underneath) will temporarily restore cooling, but the underlying defrost component failure must be addressed.
Dirty or blocked condenser coils
Condenser coils on the back or underside of the fridge release heat from the refrigeration cycle. In Calgary homes with regular dust accumulation or pet hair, coils can become coated within 1–2 years, dramatically reducing cooling efficiency. This is an easy, low-cost fix: coil cleaning with a vacuum and coil brush. If your fridge is running but not cooling as well as it used to, check the condenser coils first.
Compressor failure
The compressor is the heart of the refrigeration system. A failed compressor means no cooling at all — the fridge will be silent (no hum) or will start and stop rapidly (short-cycling). Compressor replacement is the most expensive fridge repair, typically $350–$600 in Calgary. For fridges over 10 years old, we honestly evaluate whether replacement makes more sense. For premium brands (Sub-Zero, Miele), compressor repair is almost always worth doing given the $5,000+ replacement cost.
Refrigerant leak
Refrigerant leaks are less common than mechanical failures but do occur, particularly in older fridges with copper tubing that has corroded. Symptoms: the compressor runs continuously, the fridge is slightly cool but never reaches target temperature, and you may notice a faint chemical smell. Refrigerant handling requires certified technicians under Canadian environmental regulations. We are certified for refrigerant recovery, evacuation, and recharge.
What to do right now if your Calgary fridge isn't cooling
- Check the temperature setting — confirm it hasn't been accidentally changed (common in homes with children or after a power outage).
- Check condenser coils — pull the fridge away from the wall and vacuum the coils if they're dusty.
- Check door seals — close a piece of paper in the door; if it slides out easily, the seal is failing and warm air is infiltrating.
- Move food to a neighbour's freezer or get ice if the fridge has been warm for more than 2 hours.
