Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the unit. Do not attempt to open sealed refrigerant components.
Steps:
- Clean airflow path: Remove and wash the air filter. Vacuum dust from evaporator and condenser coils.
- Check for icing: After running briefly (if possible), inspect the evaporator. If only a small section ices or frost is uneven, it may indicate low refrigerant.
- Sensor check: Locate the evaporator sensor and ensure it is properly attached and wiring is intact. Replace the evaporator sensor if it is damaged.
- Leak signs: Look for oily residue on refrigerant tubing or joints, which can indicate a leak.
When to call a technician: If cleaning and sensor checks do not clear F0, a sealed system issue (low refrigerant, restriction) is likely. Only a licensed refrigeration technician should perform leak detection, evacuation, and recharging.
