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.
Causes, in order of likelihood
| Cause | How often | Typical cost |
|---|---|---|
| Evaporator coils iced over | Most common | $220–$500 |
| Failed evaporator fan | Common | $200–$420 |
| Overpacked, blocking vents | Common | DIY |
| Garage installation below the appliance's rated ambient | Common | DIY assessment |
| Failed door seal | Common | $150–$350 |
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.
