International Comfort Products T8DNL075F16B1 Defrost Sensor Board
The defrost control board initiates the defrost cycle which aids to remove frost build-up that may accumulate. It is influenced by a temperature sensor located in the outdoor unit to make the decision on when to begin.
What are some indications that my outdoor defrost sensor board really needs to be replaced?
- Defrost session will not kick in especially when there is frost that needs to be removed
- Your HVAC system will end up not running due in part to way too much frost build-up
- The primary control board may issue a type of error code referring to a failing defrost control board
