Carrier 38QR Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrost sequence which may be necessary to rid your unit of frost that can build up. The board is relayed information from a specific sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Some clues the AC defrost sensor board is going out
- The main control board could signify an alphanumeric error code if the defrost board fails
- Your system could end up not running for the simple fact of the fact that there is too much frost
- Unit defrost session has not run for quite some time even when there is a large quantity of frost on the external unit
