Carrier 50JS Defrost Sensor Board
The defrost sensor board determines when or if to start an important defrosting cycle which actually helps to get rid of the frost that collects on the outdoor unit. The defrost sensor board depends on a sensor located somewhere by the condenser to agree when to initiate the defrosting cycle.
Major symptoms your Carrier defrost sensor board needs a replacement ASAP
- The defrost sequence refuses to initiate especially when there is a rather large amount of frost on the unit
- The primary control board might give out an error of some type referring to a bad defrost board
- The system will end up not running due in part to the amount of frost on the outdoor unit
