International Comfort Products FBF050B12A1 Defrost Sensor Board
The defrost sensor control board determines when or if to start an important defrosting cycle which helps to remove frost build-up that may accumulate. The defrost sensor board looks to a defrost sensor that can be found near the condenser, in order to verify when the defrost cycle should begin.
What signals that my outdoor defrost sensor board is on its last leg?
- Self defrost sequence never starts especially when there is a rather large amount of frost built up
- AC and heating system could stop operating due to the safety issue that the frost poses
- The primary control board might issue a specific error code produced when the defrost board is bad
