International Comfort Products T9MPD080J16B1 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrost sequence which may be needed in order to defrost your outdoor unit. The defrost board is relayed information from a defrost sensor that can be found near the condenser, in order to decide when the defrost cycle should begin.
What are some hints that my AC defrost sensor board needs replacing?
- Self defrost sequence will not kick in especially when there is frost that has built up
- Your main control board could signify an error signal referring to a failing defrost control board
- The system may not run at all because of too much frost
