What it means
FHCC means the indoor unit has detected a refrigerant sensor malfunction. The manual says the sensor cannot be repaired and must be replaced with the manufacturer-specified sensor.
Urgency
advisory
Schedule service before relying on the unit because the leak-detection sensor is part of the R-454B safety system.
Likely causes
- Refrigerant sensor malfunction
- Failed refrigerant sensor module
- Sensor at or beyond its service life
- Sensor harness or connector problem
Homeowner fix
Power cycle once only if safe. If FHCC remains or returns, leave the unit off and do not open the indoor unit.
When to call a pro
Call a licensed HVAC technician if FHCC appears. Tell them the Blueridge manual identifies FHCC as refrigerant sensor malfunction.

Sensor replacement is normally the right repair. Full system replacement is rarely justified unless the unit has other major failures.
