Possible Causes
How to Fix / Troubleshooting
Safety: Do not attempt to open or recharge the sealed refrigeration system yourself. Refrigerant handling requires certification and specialized tools.
User-level checks:
- Airflow: Ensure filters and coils are clean and that there is no blockage of intake or exhaust air.
- Operating conditions: Verify that doors and windows are closed and that the room size is within the unit's rated capacity.
- Reset: Unplug the unit for 10–15 minutes, then plug back in and test. Observe whether F0 returns quickly.
If F0 persists and cooling performance is poor (weak airflow temperature drop, compressor short-cycling), the unit likely has a refrigerant or compressor issue. Contact a Whirlpool-authorized service provider for leak detection, pressure testing, and repair options.
