Goodman GSX160481 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrosting phase if necessary, to get rid of the frost that collects on the outdoor unit. The board relies on a temperature sensor which is near the condenser somewhere, in order to decide when to initiate the defrosting cycle.
Clues to watch for to know the defrost sensor board is not going to last much longer
- The main board could throw a particular error code when the defrost control board refuses to initialize properly
- The AC may not work due in part to the amount of frost on the outdoor unit
- The defrost sequence has not run for a while even though there is a large amount of frost that makes the unit run like crap
