International Comfort Products H8MPN100F14B1 Defrost Sensor Board
The defrost sensor board determines when or if to start the defrosting phase which helps to rid your unit of frost that can build up. The defrost sensor board depends on a specific sensor that can be found near the condenser, in order to determine when the defrost cycle should begin.
Major clues your defrost board will not live much longer
- AC and heating system could end up not running for the simple fact of too much frost
- The control board could signify an error code when the defrost control board refuses to initialize properly
- Defrost mode has not run for quite some time even though there is a large amount of frost that has built up
