International Comfort Products N9MP2125J20C2 Defrost Sensor Board
The defrost control board will determine when to initiate the defrost sequence which may be necessary to keep your outdoor unit from plugging up. The board depends on a defrost sensor located near the condenser to decide when to initiate the defrosting cycle.
Subtle hints your defrost board will need replacing
- Your main control board might issue an error signal if the defrost control board fails
- The system may end up not running due to the fact of the safety issue that the frost poses
