Carrier 38BYG024 Defrost Sensor Board
The defrost sensor board determines when or if to start an important defrosting cycle which aids to get rid of the frost that collects on the outdoor unit. The board depends on a sensor located somewhere by the condenser to decide when the defrost cycle should begin.
Major clues of an unhealthy outdoor defrost sensor board
- The primary control board might give out an error code when the defrost board fails
- The system may stop operating due to the fact of way too much frost build-up
- Self defrost sequence never runs despite the fact that there is a lot of frost that has built up
