Error Code 81E
Compressor motor winding open or short circuit failure
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: 81 E
What This Means
Compressor restricted or locked; Three-phase motor winding short (U, V, W); IPM fault in inverter board; Low system voltage or refrigerant issues
What actually causes this:
Compressor motor winding shorted, stuck pump mechanism, or internal mechanical failure
First Thing to Check
Check for continuity between U, V, W motor terminals; shorts indicate bad compressor
Parts Involved
How to Fix
- 1
Check for shorts between U, V, W compressor motor terminals
- 2
Check IPM pins #1-26 on inverter board for shorts
- 3
Check IPM operating voltage is above DC 13.5V
- 4
Check compressor thermal overload is not tripped
