Carrier 50JS042300 Defrost Sensor Board
The defrost sensor control board determines when or if to start an important defrosting cycle in order to keep your outdoor unit from plugging up. The control board relies on a sensor which is near the condenser somewhere, in order to agree when to begin.
Major signs of a barely functioning Carrier defrost sensor board
- AC and heating system could stop operating at all because of lack of airflow through the outdoor unit
- The main control board might issue a particular error code produced when the defrost control board fails to receive a signal
- The defrost sequence will not initiate even when there is a large quantity of frost on the outdoor unit
