Lennox G43UF Defrost Sensor Board
The defrost control board initiates the defrost cycle which actually helps to continue normal heating and cooling operations. The control board looks to a temperature sensor which is near the condenser somewhere, in order to decide when the defrost cycle should begin.
Some warnings of a dying defrost board
- Your HVAC system will not work due to the fact of lack of airflow through the outdoor unit
- Your main control board could display an error of some type when the defrost board fails
- Unit defrost session never runs despite the fact that there is a lot of frost built up
