Bush freezer displays E8; internal fan may not run, or there may be poor air circulation and uneven temperatures.

Safety first: Unplug the freezer before removing internal panels or touching the fan assembly.

E8 typically indicates a problem with the evaporator fan motor in Bush upright freezers.

• Check for fan operation: With the door switch held closed (if present) and the unit powered, the fan should run when the compressor is on. If it does not, unplug and continue.
• Access the fan: Remove the internal rear panel in the freezer compartment to expose the evaporator and fan housing.
• Inspect for ice build-up: Look for ice blocking the fan blades or housing. If present, fully defrost the area using warm air and towels. Do not use sharp tools.
• Test the fan motor: Disconnect the fan connector and measure resistance across the motor terminals. An open circuit indicates a failed motor.
• Check wiring: Inspect the harness from the fan to the control board for damage or loose plugs.
• Replace the fan motor: If faulty, install a new evaporator fan motor suitable for your Bush model. Transfer the fan blade if necessary and ensure it spins freely.
• Reassemble and test: Refit the rear panel, restore power, and confirm that the fan runs and E8 clears.

If the fan tests good but does not receive voltage when it should, the main control PCB or wiring may be defective and require professional diagnosis.
