Lennox CB27UH-048 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrost cycle which may be needed in order to rid your unit of frost that can build up. It looks to a sensor located near the condenser to verify when the defrost cycle should begin.
What warnings should I watch out for to know if my AC defrost sensor board is almost going bad?
- Defrost mode has not run for a while even though there is quite a bit frost that has built up
- The HVAC system control board might issue an error code when the defrost control board refuses to initialize properly
- The AC may stop functioning due to the amount of frost on the outdoor unit
