International Comfort Products H2A330GKA100 Defrost Sensor Board
The defrost sensor control board determines when to initiate an important defrosting cycle which helps to defrost your outdoor unit. The defrost board relies on a specific sensor located near the condenser to make the decision on when to begin.
Signs of a deteriorating outdoor defrost sensor board
- The main control board might give out an error of some type when the defrost board fails
- The system may not run due in part to way too much frost build-up
- The defrost sequence will not initiate even though there is a lot of frost that has built up
