Goodman GKS90704CX Defrost Sensor Board
The defrost control board determines when or if to start the defrost sequence if necessary, to remove frost build-up that may accumulate. The defrost board relies on a defrost sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Subtle cues of a deteriorating Goodman defrost sensor board
- Your main control board may signify an error of some type produced by a bad defrost control board
- The system will stop working for the fact of way too much frost build-up
- Self defrost sequence will not kick in even though there is a lot of frost that needs to be removed
