Payne PG8MAA042090 Control Board
The Payne PG8MAA042090 control board is created to control the gas valve, the igniter, most sensors as well as the blower all at once. Your furnace or AC will not run at all without the board installed as it should be according to the manufacturer. The board you choose will need to be a match with your existing board and be compatible with both the brand and model of the unit in question. You must be careful upon picking a replacement board due to so many small differences in particular brands and their models.
Signs of a defective primary control board
- AC or heating system declines to work well
- The HVAC system has to be reset habitually for the furnace or AC to kick on
- There seems to be a flashing error code directly on the control board
