Goodman GMH80904BN Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrost sequence which actually helps to rid your unit of frost that can build up. The defrost sensor board looks to a defrost sensor which is near the condenser somewhere, in order to verify when the defrost cycle should begin.
Some clues your outdoor defrost sensor board will need replacing
- Most systems will not run due to the safety issue that the frost poses
- Self defrost sequence never begins despite the fact that there is quite a bit frost on the external unit
- The primary control board might give out an error code when a defrost board fails to initialize
