Bryant GT-PG Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrost cycle which aids to continue normal heating and cooling operations. The board relies on a temperature sensor located in the outdoor unit to decide when to begin.
Some warnings your outdoor defrost sensor board should need replacing
- Unit defrost session will not kick in even when there is a large quantity of frost built up
- Your HVAC system will not work at all because of the fact that there is too much frost
- The primary control board could throw a specific error code if the defrost board goes out
