Lennox CBX26UH-024 Defrost Sensor Board
The defrost sensor control board commences an important defrosting cycle which helps to get rid of the frost that collects on the outdoor unit. The board looks to a temperature sensor that can be found near the condenser, in order to make the decision on when to begin.
Important clues to watch for in a bad Lennox defrost sensor board
- Your system could end up not running because of way too much frost build-up
- The primary control board might issue an error code when encountering a problem
- Defrosting will not kick in despite that there is a large amount frost on the external unit
