Freezer Not Freezing

A freezer that will not hold temperature is usually suffering from blocked airflow — iced-over evaporator coils, a failed fan, or a door seal that is letting warm air in.

1. Evaporator coils iced overTechnician job

How to check: Remove the rear interior panel. Solid frost across the coils means the defrost cycle is not running.

The fix: Manually defrost to confirm, then replace the failed defrost heater, thermostat or timer.

2. Failed evaporator fanTechnician job

How to check: No fan noise with the door switch held in.

The fix: Fan motor replacement.

3. Overpacked, blocking ventsYou can check this

How to check: Boxes pressed against the rear or side vents stop cold air circulating.

The fix: Leave clearance around the vents.

4. Garage installation below the appliance's rated ambientYou can check this

How to check: A garage unit that thaws in cold weather is usually not broken. Below roughly 40°F ambient many standard refrigerator-freezers stop cycling the compressor, so the freezer slowly warms.

The fix: Use a garage-ready model, or move the unit somewhere temperature-controlled.

5. Failed door sealTechnician job

How to check: Frost building around the door edge points at a leaking gasket.

The fix: Replace the gasket.

When to call a technician

Repeated icing after a manual defrost means a defrost-circuit component has failed and needs replacing.
