Lennox Elite 14 Defrost Sensor Board
The defrost sensor board initiates the defrosting phase which aids to rid your unit of frost that can build up. The control board is relayed information from a temperature sensor which is near the condenser somewhere, in order to verify when to begin.
Key clues of an ailing defrost board
- The system may end up not running for the simple fact of way too much frost build-up
- The primary control board may show a particular error code when the defrost board fails
- Unit defrost session will not kick in especially when there is a rather large amount of frost that has built up
