Display shows E7; evaporator fan may not run, causing warm temperatures and frost patterns only on part of the coil.

Safety first: Disconnect power before removing freezer panels. Beware of sharp metal and ice.

Steps:

• Access evaporator fan: Remove freezer shelves and the rear interior panel to expose the evaporator fan assembly.
• Inspect for ice: Look for ice buildup around the fan shroud or blades. If present, defrost the area with towels and gentle warm air.
• Spin test: With power off, spin the fan blade by hand. It should rotate freely without grinding.
• Voltage test: Restore power and close the door switch (use tape to hold it closed). When the compressor is running, check for proper voltage at the fan motor connector. If voltage is present but the fan does not run, the motor is bad.
• Check harness: Inspect wiring from the fan to the cabinet pass-through and to the control board for damage.

Corrective action: Replace the evaporator fan motor assembly if it is seized or does not run with correct voltage. Ensure the fan is correctly oriented and that the shroud is reinstalled to direct airflow properly.
