Possible Causes

Failed tachometer signal from evaporator fan, Damaged fan motor with built-in Hall sensor, Broken feedback wire to main board, Faulty fan speed monitoring circuit on board

How to Fix / Troubleshooting

Safety first: Unplug the freezer before working near the fan or evaporator.

Step-by-step checks:

  • 1. Access evaporator fan: Remove the inner rear panel to expose the fan assembly.
  • 2. Inspect wiring: Check the multi-wire harness to the fan motor for damage or loose connectors. Reseat the plug.
  • 3. Replace fan motor: On models with electronically commutated fans, the speed feedback is integrated. If E18 persists and the fan is noisy, stalls, or runs erratically, replace the fan motor assembly.
  • 4. Board diagnosis: If a new fan does not resolve the error, the monitoring circuit on the main board may be defective and the board should be replaced.
