Carrier 38TKB060 Defrost Sensor Board
The defrost control board initiates the defrosting phase which may be needed in order to continue normal heating and cooling operations. It relies on a defrost sensor located somewhere by the condenser to make the decision on when the defrost cycle should begin.
Subtle cues of an ineffective AC defrost sensor board
- The defrost feature never begins even when there is a large quantity of frost in the way
- Your main control board could signify a type of error code referring to a bad defrost board
- The system will stop functioning due to the safety issue that the frost poses
