Payne PG8JAA036045 Control Board
The control board is designed to operate everything including the gas valve, the igniter, all the various sensors as well as the blower all in one unit. Heating and cooling systems will not even be able to function lest this board is accurately installed and configured. It is of utmost importance while choosing a new control board because of the wide variety of particular brands and their models. A matching board should have part numbers that match both the brand and model of HVAC system.
Symptoms of a defective main circuit board
- The unit will not operate at all
- When turned on, there is a strange code shown on the front of the control board
- The entire system needs to be reset many times a week for the furnace or AC to kick on
