International Comfort Products PGMD42G115 Defrost Sensor Board
The defrost control board controls when to launch an important defrosting cycle in order to continue normal heating and cooling operations. The board relies on a sensor which is near the condenser somewhere, in order to agree when the defrost cycle should begin.
Signals the defrost sensor board will soon need to be replaced
- AC and heating system could not work due in part to the fact that there is too much frost
- Your main control board could throw an error of some type if the defrost board goes out
- The defrost feature never begins even when there is a large quantity of frost that needs to be removed
