Possible Causes
Blocked condenser coil or exhaust grille, Failed condenser fan motor, High ambient temperature beyond unit rating, Faulty high-temperature sensor or thermal switch on condenser
How to Fix / Troubleshooting
Safety: Unplug the unit and allow it to cool before working near the compressor or coils.
- Check placement: Ensure the dehumidifier is not placed in a confined space or near a heat source. Provide adequate clearance around the exhaust.
- Clean condenser: Remove the rear panel to access the condenser coil. Use a soft brush and vacuum to remove dust and lint from the fins.
- Verify fan operation: With the panel temporarily reinstalled and the unit powered, observe whether the condenser fan starts when the compressor runs. If the fan does not run, unplug the unit and test the condenser fan motor for free rotation and continuity.
- Inspect thermal sensor: Locate any thermal switch or sensor attached to the condenser tubing. Check for loose mounting or damaged wires.
- Replace faulty parts: Replace a non-spinning condenser fan motor or a defective condenser temperature sensor/thermal switch with OEM Comfee parts.
- Professional service: If E7 persists despite good airflow and fan operation, a technician should evaluate for deeper electrical or refrigerant issues.
