How to Fix / Troubleshooting

Safety first: Unplug the freezer before accessing the fan area.

  • Access fan housing: Remove the internal rear panel to expose the evaporator and fan assembly.
  • Clear ice: If ice is contacting the fan, perform a full manual defrost and check the defrost system (heater and thermostat) for faults.
  • Inspect fan blade: Ensure the blade is not cracked or rubbing on the housing. Replace the fan blade if damaged.
  • Replace fan motor: If the motor is noisy or does not run when powered, install a new evaporator fan motor compatible with your Bush freezer.

After repair, reassemble and verify quiet, smooth fan operation.
