What This Means
Compressor wire connection problem; Bad soldering on inverter PCB; Short in inverter PCB components; Compressor or refrigerant cycle issue
What actually causes this:
A phase wire to the compressor is open or has high resistance, preventing the MICOM from sensing rotor position
First Thing to Check
Check all three compressor phase wires at CN04 for continuity and tight connections
Parts Involved
How to Fix
- 1
Check compressor wire connections at CN04
- 2
Check soldering on inverter PCB for shorts
- 3
Verify compressor and refrigerant cycle are normal
- 4
Check that compressor is not locked rotor (spinning less than 1000 RPM for over 5 seconds)
