Lennox XP19-024 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin an important defrosting cycle which actually helps to rid your unit of frost that can build up. The defrost sensor board depends on a specific sensor located in the outdoor unit to agree when to begin.
Simple signals your Lennox defrost sensor board will not live much longer
- AC and heating system could not operate due to the safety issue that the frost poses
- Defrost mode refuses to run even though there is quite a bit frost on the outdoor unit
- The main circuit board might give out an error code produced when the defrost control board fails to receive a signal
