Carrier 58MXB120F10120 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost sequence which may be needed in order to keep the outdoor unit free from frost build-up. The board is influenced by a defrost sensor located in the outdoor unit to agree when to begin.
Major indications of a weak AC defrost sensor board
- The main board may show an alphanumeric error code if the defrost board goes out
- Self defrost sequence does not run especially when there is frost on the external unit
- The whole system may end up not running for the simple fact of the frost blocking the flow of air
