Lennox XC16-024 Defrost Sensor Board
The defrost control board controls if and when to commence the defrost cycle which may be needed in order to continue normal heating and cooling operations. The defrost board depends on a specific sensor located in the outdoor unit to ascertain when the defrost cycle should begin.
What signals that my AC defrost sensor board is about to go out?
- The main board might give out a particular error code when a defrost board fails to initialize
- Your HVAC system will end up not running due in part to frost blocking the airflow outside
- The defrost sequence has not run for a while especially when there is frost on the external unit
