International Comfort Products N9MP2100J20C2 Defrost Sensor Board
The defrost control board initiates the defrost sequence which assists to keep your outdoor unit from plugging up. The defrost board relies on a temperature sensor located somewhere by the condenser to make the decision on when to begin.
What are the clues to watch out for to know my defrost board is in need of a replacement?
- The main board could display an error number produced when the defrost control board fails to receive a signal
- Your HVAC system will stop working for the fact of way too much frost build-up
- The defrost sequence has not run for quite some time despite that there is a large amount frost in the way
