International Comfort Products NTG3075FBA3 Defrost Sensor Board
The defrost sensor board determines when to initiate the defrost cycle which may be necessary to keep your outdoor unit from plugging up. The board depends on a sensor located near the condenser to determine when to initiate the defrosting cycle.
Red flags the defrost sensor board is on its last leg
- The defrost feature has not run for a while especially when there is a rather large amount of frost that needs to be removed
- The HVAC system control board may show a type of error code referring to a bad defrost board
- The HVAC system could end up not running at all because of way too much frost build-up
