Lennox OF24-105 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrost sequence in order to continue normal heating and cooling operations. The defrost board looks to a defrost sensor located somewhere by the condenser to make the decision on when to initiate the defrosting cycle.
What are the clues to watch out for to know my outdoor defrost sensor board has to be replaced?
- The primary control board could throw an alphanumeric error code produced when the defrost control board fails to receive a signal
- Defrosting will not kick in even though there is a large amount of frost that needs to be removed
- Air conditioning may cease to operate for the fact of way too much frost build-up
