Goodman GMS80453AN Defrost Sensor Board
The defrost sensor control board will begin an important defrosting cycle which may be needed in order to defrost your outdoor unit. The defrost board is influenced by a sensor located in the outdoor unit to determine when to initiate the defrosting cycle.
What are the signs that the defrost sensor board is not working right?
- Defrost session has not run for a while especially when there is a rather large amount of frost on the external unit
- Your main control board might give out an error code produced by a failing defrost board
- Air conditioning may stop working due to the fact of way too much frost build-up
