International Comfort Products NNE050B12G1 Defrost Sensor Board
The defrost sensor board will begin an important defrosting cycle which may be necessary to keep the outdoor unit free from frost build-up. The board looks to a defrost sensor located in the outdoor unit to determine when to begin.
Important signs your defrost board will not last the year
- The main circuit board could display a specific error code produced when the defrost board is bad
