International Comfort Products N9MP1080F16C2 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrosting phase in order to get rid of the frost that collects on the outdoor unit. The board looks to a sensor located somewhere by the condenser to agree when to begin.
Key symptoms of a dying defrost sensor board
- The control board could throw an error code if the defrost control board fails
- Defrost session does not begin even though there is a lot of frost on the outdoor unit
- The HVAC system could not operate at all because of way too much frost build-up
