How it shows on the unit Operation lamp blinking during operation
Applies to 3 models
FVXM25FV1B9, FVXM35FV1B9, FVXM50FV1B9
What this means
The unit has stopped or entered standby because of a possible airflow problem, a multi-system mode conflict, or another abnormal condition. In a multi-system, blinking can occur without a system fault when indoor units request incompatible modes.
What you can check yourself
- Clean the air filters, remove obstructions from indoor and outdoor air inlets/outlets, and power-cycle the unit. In a multi-system, set connected indoor units to compatible modes. If the lamp continues blinking, contact the dealer.
