Possible Causes

Evaporator fan not running, Air vents blocked by food, Frost buildup on evaporator coil, Interior fan shroud misaligned

How to Fix / Troubleshooting

Safety: Unplug the freezer before removing interior panels.

Check airflow:

  • Ensure food packages are not blocking interior air vents on the back or sides.
  • Do not stack items directly against the rear wall; leave space for air to circulate.

Verify evaporator fan operation:

  • With the door open, press the door switch (if present) to see if the fan runs. If not, follow the evaporator fan motor troubleshooting steps (similar to E8).

Inspect for frost buildup:

  • If the rear interior panel is heavily frosted, unplug the unit and allow it to fully defrost.
  • After defrosting, check the defrost system components (thermostat, heater, thermistor) and repair as needed.

Reassemble and test: Restore power and monitor temperatures at different shelf levels over 24 hours to confirm even cooling.
