Possible Causes

Partial refrigerant leak, Frost-clogged evaporator from defrost failure, Weak compressor, Freezer door gasket leak

How to Fix / Troubleshooting

Safety: Unplug before removing panels or defrosting manually.

  • 1. Check temperature setting: Ensure the freezer is set to around -18°C (0°F).
  • 2. Inspect for frost on back wall: Heavy frost indicates defrost failure. Access the evaporator and test heater, thermostat, and sensor.
  • 3. Check door seal: Inspect the freezer gasket for gaps or damage. Replace if not sealing properly.
  • 4. Observe frost pattern: With the rear panel removed and unit running (technician-level check), a healthy system shows even frost across the evaporator. Frost only on a small section suggests a sealed system problem requiring professional service.
