International Comfort Products NDC7100BHA2 Defrost Sensor Board
The defrost sensor control board commences an important defrosting cycle which may be needed in order to keep the outdoor unit free from frost build-up. It is relayed information from a sensor located near the condenser to verify when to begin.
Some clues of a worsening AC defrost sensor board
- Your system could stop working due in part to frost blocking the fins on the outside unit
- The main circuit board may issue an error of some type produced by a failing defrost board
- Self defrost sequence has not run for quite some time especially when there is frost that makes the unit run like crap
