Carrier 58STX04510012 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost sequence which may be needed in order to keep your outdoor unit from plugging up. The defrost sensor board is influenced by a sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
Clues your outdoor defrost sensor board is on its last leg
- Your main control board could display a type of error code when a defrost board fails to initialize
- Most systems will end up not running because of the safety issue that the frost poses
- The defrost sequence does not run even though there is quite a bit frost in the way
