32 / E32
Equipment is experiencing high-temperature faults on the outdoor unit control board
This code typically points to
- Ambient air conditions too high
- Stop valve not completely open
- Cooling bracket screw(s) missing/not properly fastened in very low ambient condition
- No/poor thermal grease coating between cooling plumbing and cooling bracket on control board
- No/low/limited flow through control-board cooling circuit from line restriction or low refrigerant
Next checks to confirm
- Cycle power and retry in usable ambient range
- Check grease application in very low ambient condition
- Check for line restriction
- Check refrigerant charge level
- Verify stop valve fully open and repair if needed
