What it means
H7 means the fan inverter/power module temperature is abnormal on applicable outdoor units. Homeowner checks stop at outdoor airflow.
Urgency
advisory
This is not usually an immediate safety hazard, but do not keep resetting it. Try the safe homeowner check below; if the code comes back, schedule service.
Likely causes
- Debris, ice, or a foreign object restricting the fan
- Loose fan-motor plug, damaged fan lead, or bad feedback signal
- Fan motor winding, phase, or rotation fault
- Control board fan-drive fault after the motor checks out
Homeowner fix
Turn the unit off, clear only loose debris around the outdoor unit, and restore power once after it cools. If H7 returns, stop using the unit.
When to call a pro
Call a licensed HVAC technician if H7 returns. Tell them the MXM table lists fan IPM temperature error.

This is normally repairable, but it is not a homeowner repair. If the unit is older, out of warranty, or a technician quotes a major compressor, inverter, board, or sealed-system repair, compare the quote with replacement.
