How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before removing freezer panels.

Step-by-step:

  • Manual defrost: Remove food from the freezer and take off the rear interior panel. Allow all ice on the evaporator and surrounding area to melt completely.
  • Inspect components: Locate the defrost heater (usually at the bottom of the evaporator) and thermostat (clipped to tubing). Look for obvious damage or burnt spots.
  • Reassemble and test: After defrosting and reassembly, plug in the fridge and monitor for several days.

Action: If ice buildup returns and airflow is again restricted, the defrost components should be tested with a multimeter and replaced as needed. This is typically a job for a trained technician.
