Goodman GPH1330H21A Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrost cycle which may be needed in order to remove frost build-up that may accumulate. The defrost sensor board is relayed information from a temperature sensor that can be found near the condenser, in order to agree when to initiate the defrosting cycle.
Important hints your Goodman defrost sensor board has little life left
- The main circuit board may throw an error number if the defrost board fails
- Defrost mode has not run for a while even when there is a large quantity of frost in the way
- The AC may stop running at all because of the frost blocking the flow of air
