Carrier 38YZA042 Defrost Sensor Board
The defrost sensor control board instructs the system to activate an important defrosting cycle which actually helps to get rid of the frost that collects on the outdoor unit. The defrost board relies on a defrost sensor located in the outdoor unit to ascertain when to begin.
Some clues of a deteriorating outdoor defrost sensor board
