Carrier 48GP048130300 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrosting phase if necessary, to continue normal heating and cooling operations. The defrost sensor board looks to a sensor located somewhere by the condenser to verify when to begin.
Key clues of an inadequate defrost sensor board
- Air conditioning may end up not running for the simple fact of the safety issue that the frost poses
- Defrosting will not initiate even though there is a large amount of frost on the unit
- Your main control board may show an alphanumeric error code produced by too much frost
