Why Is My Freezer Not Freezing? Common Causes & Quick Fixes

Check the Basics First

Temperature setting – The dial or digital control should be set around –18°C (0°F). It’s easy to nudge it during cleaning or after a power cut.

Door seal – Grab a piece of paper and close the freezer door over it. If you can pull the paper out easily, the gasket is leaking air. Clean the seal with warm, soapy water; if it’s cracked, replace it.

Power supply – Verify the plug is snug and the circuit breaker hasn’t tripped. A loose plug or tripped breaker will stop the compressor from running.

Dig Deeper: Mechanical Issues

Frost buildup – Ice thicker than a quarter can block airflow. Defrost the freezer by unplugging it, letting the ice melt, and wiping it dry. Leave the door open for a few hours after plugging it back in.

Condenser coils – Dusty coils reduce cooling efficiency. Pull the freezer away from the wall, locate the coils (usually at the back or underneath), and vacuum them gently.

Defrost timer or heater – On frost‑free models, a faulty timer can stop the automatic defrost cycle, causing ice to jam the vents. Hearing the timer click every few hours? If not, it may need replacement.

Thermostat or sensor – A broken thermostat won’t signal the compressor to kick in. If the freezer stays warm even when set low, the thermostat is likely the problem.

Compressor or start relay – These are the heart of the cooling system. If you hear a click but no humming, the start relay might be stuck. This part is best checked by a qualified technician.
