International Comfort Products T8MPN125J20B1 Defrost Sensor Board
The defrost control board instructs the system to activate the defrost sequence which assists to get rid of the frost that collects on the outdoor unit. The board is relayed information from a specific sensor located near the condenser to make the decision on when to begin.
Simple warnings that your defrost sensor board is about to go out?
- The defrost feature never starts even though there is excessive frost on the unit
- The main board may signify an error signal produced when the defrost board is bad
- The system may not run due in part to frost blocking the fins on the outside unit
