Why Is My Fridge Running But Not Cooling?

If your refrigerator motor is running but the temperature inside keeps climbing, something in the cooling system has failed. The good news is that many of these issues are fixable — and a certified technician can usually diagnose the problem in a single visit.

Dirty or Blocked Condenser Coils

Condenser coils release heat from the refrigerant as it circulates through the system. When coils are coated in dust and debris, they can't release heat efficiently. Coils are typically located at the back or underneath the unit. Cleaning them every 6–12 months can prevent this problem entirely.

Evaporator Fan Not Running

The evaporator fan circulates cold air throughout the fridge and freezer compartments. If the fan fails or its blade is obstructed by ice buildup, cold air won't reach the refrigerator section even if the compressor is running.

Defrost System Failure

Modern fridges run automatic defrost cycles to prevent frost buildup on the evaporator coils. If the defrost heater, thermostat, or timer fails, frost accumulates until it blocks airflow completely. The freezer may feel cold while the fridge section stays warm.

When to Call a Technician

If basic checks don't resolve the issue, it's time to call a professional. Refrigeration systems involve refrigerant handling that requires a licensed technician. Call (780) 782-9600 for same-day fridge repair in Edmonton.
