How to Fix / Troubleshooting
Safety: Unplug the unit before removing panels.
Steps to fix F2:
- Access evaporator coil: Remove the front or rear cover to expose the evaporator coil and attached sensors.
- Locate defrost sensor: It is typically clipped to the coil or attached with a metal clip or tape.
- Check attachment: Ensure the sensor is firmly in contact with the coil surface.
- Inspect wiring: Follow the sensor leads to the PCB, checking for damage or loose connectors.
- Replace sensor: If wiring is intact but F2 persists, install a new Homedics defrost / coil temperature sensor.
- Board issue: Continued F2 after sensor replacement suggests a control board fault requiring professional service.
