International Comfort Products H9MPD080J16A2 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrosting phase which may be needed in order to remove frost build-up that may accumulate. It relies on a temperature sensor that can be found near the condenser, in order to decide when to begin.
How can I tell if my AC defrost sensor board is not working right?
- Most systems will stop running due to the fact of the frost issue
- The main circuit board might give out an error signal referring to a failing defrost control board
- Defrost mode refuses to initiate even though there is excessive frost on the unit
