Carrier 50XL-A48 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrost sequence which assists to keep your outdoor unit from plugging up. It is influenced by a temperature sensor which is near the condenser somewhere, in order to verify when to begin.
What happens when my Carrier defrost sensor board is crapping out?
- The defrost sequence never initiates especially when there is frost that needs to be removed
- The primary control board may issue an error of some type when encountering a problem
- The whole system may stop working for the fact of the fact that there is too much frost
