What it means
FP means limiting/reducing frequency for anti-condensation protection. In plain English, the unit is reducing output to prevent condensation.
Urgency
advisory
Clean filters and avoid very low setpoints. Service is needed if it repeats.
Likely causes
- Very low cooling setpoint or humid room conditions
- Dirty filter or blocked indoor airflow
- Indoor coil temperature sensor or control issue
- Refrigerant/airflow condition making the coil too cold
Homeowner fix
Raise the cooling setpoint slightly, clean the user-removable filter, and make sure the indoor intake/outlet are not blocked. If it repeats, call for service.
When to call a pro
Call a licensed HVAC technician if FP returns after one safe reset or the condition will not clear. Tell them the official source lists FP as Limiting/reducing frequency for anti-condensation protection.
