Carrier 38YSA024 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost cycle in order to keep the outdoor unit free from frost build-up. The defrost sensor board relies on a specific sensor located in the outdoor unit to ascertain when to initiate the defrosting cycle.
Major clues to watch for in a failing defrost sensor board
- Your main control board may show an error signal produced by too much frost
- Air conditioning may end up not running due to the fact of the frost blocking the flow of air
- Unit defrost session does not run despite the fact that there is a lot of frost that has built up
