What it means
Defrost is normal in heating. The indoor fan may pause, the outdoor unit may steam, and heating should resume after the cycle finishes. Manual trigger: Defrost means the heat pump is clearing ice from the outdoor coil.
Urgency
Not an error
This is a normal status indication, not an error, unless comfort is poor, water is present, or the indication never clears.
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
Let defrost finish. Keep the outdoor unit clear of snow buildup around the base, but do not chip ice from the coil.
When to call a pro
Call for service if defrost never clears, the outdoor unit is encased in ice, or heating does not resume after the cycle.
Repair vs replace
This is a normal operating status, not a repair-or-replace decision.
