Freezer shows E7 and the internal fan may not run; cooling is weak and uneven.

Safety: Unplug the freezer before accessing the fan area. Fan circuits are live when powered.

Procedure:

• Access the evaporator fan: Remove shelves and the rear interior panel. The fan is mounted near the top or center of the evaporator compartment.
• Check for ice blockage: Inspect the fan blades and shroud for ice buildup. If present, fully defrost the area with the unit unplugged. Do not force the blades through ice.
• Spin test: Gently spin the fan by hand. It should rotate freely without grinding. If stiff or noisy, replace the fan motor assembly.
• Electrical test: Disconnect the fan connector. Measure resistance across the motor terminals; compare to specifications (often 50–300 Ω for DC fans). An open circuit indicates a failed motor.
• Check wiring: Inspect the harness from the fan to the main PCB for damage or loose connectors. Repair as needed.
• Control board: If the fan motor tests good but does not receive voltage when the compressor is running, the main control PCB fan driver may be faulty. Replacement of the PCB is required.

After repair: Reassemble the panel, restore power, and verify that the fan runs whenever the compressor is on and that the E7 code clears.
