What Does Error FP Mean?

The FP error on your Amana Air Conditioner indicates that the unit has engaged freeze protection mode due to low ambient temperatures, typically below 40°F. This mode prevents the system from operating to avoid damage. Symptoms include the unit stopping its cooling or heating operation and the FP code appearing on the control panel. The system will resume normal function once temperatures rise above 43°F.

Common Symptoms:

  • Unit stops normal cooling/heating operation
  • FP displayed on control panel or remote
  • Occurs when ambient or coil temperature is very low

Possible Causes

  • Low ambient or sensed temperature triggering built‑in freeze protection (medium)

How to Fix Error FP

DIY Fix Allow temperature to rise or adjust thermostat

  1. Ensure room/ambient temperature is above freezing.
  2. If possible, raise the thermostat setpoint to avoid continuous low‑temperature operation.
  3. Ensure the unit has proper airflow around it and vents are not blocked.

Technician Only Verify thermostat/thermistor and control operation

  1. Measure temperature at indoor sensors and validate against unit specifications.
  2. Check thermostat/thermistor wiring and sensor calibration for faults that could falsely trigger freeze protection.
  3. Confirm control board is operating normally and not sending erroneous freeze signals.

Parts needed: Thermostat/thermistor sensor, Control board wiring/connectors

🛑 When to Call a Pro:
  • If FP persists despite ambient temperatures being well above freezing and after basic checks
  • If sensors or wiring appear damaged or intermittent
  • If unit fails to resume normal operation when conditions normalize
