Carrier 38YCS042 Defrost Sensor Board
The defrost sensor board determines when or if to start the defrosting phase which may be needed in order to rid your unit of frost that can build up. The control board is relayed information from a temperature sensor that can be found near the condenser, in order to verify when the defrost cycle should begin.
Some clues the defrost sensor board is in dire straights
- AC and heating system could cease to function due to the fact of the frost issue
- The primary control board may throw an error of some type produced by a failing defrost board
- Defrost mode does not begin even though there is a lot of frost that needs to be removed
