Carrier 38BYG042 Defrost Sensor Board
The defrost control board determines when to initiate the defrost cycle which may be needed in order to keep the outdoor unit free from frost build-up. It is influenced by a defrost sensor located in the outdoor unit to make the decision on when to begin.
How do you know when your AC defrost sensor board is about to stop working?
- The main board might give out an error number referring to a failing defrost control board
- The system will stop operating for the fact of the amount of frost on the outdoor unit
- The defrost feature never starts even though there is a lot of frost on the external unit
