Possible Causes
Door frequently opened or left ajar, Damaged or dirty door gasket, Defrost heater or thermostat failure, Blocked defrost drain causing ice accumulation
How to Fix / Troubleshooting
Safety: Unplug the freezer before defrosting or working near electrical parts.
Steps to reduce frost:
- 1. Fully defrost: Remove food to a cool location, unplug the freezer, and leave the door open until all ice melts. Use towels to absorb water.
- 2. Inspect door gasket: Clean the gasket and cabinet mating surface. Replace the door gasket if torn or deformed.
- 3. Check user habits: Minimize door openings and avoid leaving the door open for extended periods.
- 4. Test defrost system: After defrosting, test the defrost heater and defrost thermostat/sensor for continuity and correct operation. Replace faulty components.
- 5. Clear defrost drain: Ensure the defrost drain is not blocked (see leak fault above).
Tip: A small amount of frost is normal, but rapid heavy buildup indicates an underlying issue that should be corrected.
