International Comfort Products PGMD36H090C Control Board
HVAC systems will not operate lest the circuit board is correctly installed. The control board is created to command everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all at once. You must do some research upon choosing a board as a replacement because of the wide variety of particular brands and their models. The chosen circuit board should have part numbers that match both the brand and specific model of your heating and cooling system.
Red flags of a weakening control board
- There is a strange code indicated directly on the control board
- Air conditioner or furnace is unwilling to do anything period
- The system board has to be turned off and back on often for it to work
