Possible Causes

Blocked air filter or grilles, dirty condenser coil, failed condenser fan motor, high ambient temperature beyond design, faulty overheat sensor on condenser or compressor

How to Fix / Troubleshooting

Safety: Unplug the unit and allow it to cool before touching internal parts.

Steps:

  • Clean filter and grilles: Wash the air filter and ensure intake and exhaust grilles are clear.
  • Inspect fan operation: With panels in place, power the unit and observe if the fan runs strongly. If the fan is weak or not running, see fan motor troubleshooting (E7).
  • Clean condenser coil: Remove rear panel and gently vacuum the warm condenser coil. Heavy dust can cause overheating.
  • Check placement: Ensure the unit is not placed in a confined space or near heat sources.
  • Sensor check: Locate the overheat sensor (often clipped to condenser tubing or compressor shell). Inspect wiring and mounting. Replace the overheat sensor if damaged.

Call a technician if F2 persists after cleaning and verifying fan operation; the compressor may be running too hot due to internal issues or incorrect refrigerant charge.
