Lennox XC21-036 Defrost Sensor Board
The defrost control board will begin the defrost cycle if necessary, to remove frost build-up that may accumulate. The board is relayed information from a temperature sensor located somewhere by the condenser to make the decision on when to begin.
What are the clues to watch out for to know my AC defrost sensor board has to be replaced?
- Your main control board may signify a particular error code referring to a failing defrost control board
- Defrost session has not run for a while even though there is a large amount of frost that makes the unit run like crap
- The system may stop functioning for the fact of way too much frost build-up
