International Comfort Products NTC5075BFC1 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrost sequence in order to keep your outdoor unit from plugging up. The board depends on a defrost sensor which is near the condenser somewhere, in order to determine when to initiate the defrosting cycle.
Major indications of a barely functioning AC defrost sensor board
- Your system could stop operating due to the fact of way too much frost build-up
- The control board could signify an alphanumeric error code produced by too much frost
- Defrost session never initiates even though there is quite a bit frost that makes the unit run like crap
