Carrier 50JX030300 Defrost Sensor Board
The defrost control board instructs the system to activate the defrost cycle which helps to get rid of the frost that collects on the outdoor unit. The board relies on a defrost sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
Easy warnings of a poorly working defrost board
- The AC may not run due in part to the frost issue
- Defrost session refuses to run even when there is a large quantity of frost that makes the unit run like crap
- The main control board may signify a specific error code produced by a bad defrost control board
