Payne PG8JAA048070AAJA Control Board
Most systems will not operate whatsoever unless this board is installed. The control board is constructed to regulate the gas valve, the igniter, all the sensors as well as the air circulator all in one unit. A matching board should have a replacement part number that matches both the brand and specific model of HVAC system. Be very careful when you choose a replacement because of the many variances of models and types.
Major symptoms your main board will need to be replaced
- There may be a flashing error code showing up somewhere on the circuit board
- The unit declines to run correctly
- The system board needs to be reset many times a day for the furnace or AC to kick on
