Carrier 48XPN024060300 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin an important defrosting cycle which may be necessary to keep your outdoor unit from plugging up. The board is relayed information from a defrost sensor located somewhere by the condenser to determine when to initiate the defrosting cycle.
Major warnings of a poorly performing defrost board
- Unit defrost session has not run for a while despite the fact that there is a lot of frost on the unit
- The system may cease to operate due in part to way too much frost build-up
- Your main control board could throw a specific error code if the defrost board goes out
