Possible Causes
Inverter IPM overheating, Poor ventilation around outdoor unit, Faulty current sensor on PCB, Partially shorted compressor winding
How to Fix / Troubleshooting
Safety first: Inverter circuitry is hazardous. Only basic external checks should be done by non-professionals.
Steps:
- Improve ventilation: Ensure the outdoor unit has adequate clearance and is not installed in a confined space trapping hot air.
- Clean condenser and fan: Dirty coils or slow fans can cause IPM overheating. Clean and verify fan operation.
- Check for repeated trips: If F6 appears quickly after reset, the IPM or compressor may be failing. Continued operation can cause catastrophic failure.
- Professional testing: A technician should measure compressor current draw and inspect the IPM module on the Blaupunkt outdoor inverter PCB. Replacement of the PCB or compressor may be required.
