International Comfort Products H8MPN100F14A1 Defrost Sensor Board
The defrost control board instructs the system to activate the defrost sequence which may be needed in order to rid your unit of frost that can build up. The defrost sensor board relies on a sensor located in the outdoor unit to determine when the defrost cycle should begin.
How do you know if your defrost board needs replacing?
- Your system could stop operating for the simple fact of the amount of frost on the outdoor unit
- The defrost sequence has not run for quite some time even though there is a large amount of frost on the external unit
- The primary control board could display a particular error code when encountering a problem
