Carrier 25HPA460A0030010 Defrost Sensor Board
The defrost sensor control board will begin an important defrosting cycle which may be needed in order to remove frost build-up that may accumulate. It is relayed information from a specific sensor located in the outdoor unit to agree when to initiate the defrosting cycle.
Some clues of a weak Carrier defrost sensor board
- The main circuit board could display an error of some type when the defrost control board refuses to initialize properly
- Unit defrost session will not initiate despite the fact that there is a lot of frost built up
