International Comfort Products H8MPV100J20C1 Defrost Sensor Board
The defrost sensor board determines when or if to start the defrosting phase which may be needed in order to get rid of the frost that collects on the outdoor unit. The control board looks to a specific sensor located somewhere by the condenser to agree when to begin.
What happens when my AC defrost sensor board is almost dead?
- The defrost feature has not run for quite some time even though there is a lot of frost in the way
- The system will not work for the simple fact of the fact that there is too much frost
- The control board may issue a specific error code when a defrost board fails to initialize
