What it means
HE means the inverter drive detected a compressor-motor protection condition. This is a serious drive/compressor diagnostic, not a homeowner repair. Manual trigger: HE means compressor demagnetization protection is active.
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
- Temporary protection event that may clear after one reset
- Airflow, power, or operating condition outside normal range
- Sensor, wiring, or control feedback problem
- Technician-only component fault identified by the service manual
Homeowner fix
Turn the system off and reset power once. Expected result: a one-time event clears; if HE returns, leave the unit off and schedule service.
When to call a pro
Call a licensed HVAC technician if HE returns or the outdoor unit cannot start. Tell them the code is compressor demagnetizing protection.
