International Comfort Products PGAD47F1K5 Control Board
The entire heating and cooling system will not operate lest this board is accurately installed and configured. The control board is constructed to command everything including the gas valve, the ignition igniter, all the various sensors and the blower all together. Be absolutely sure when you choose a control board because of the diversity of systems. The board that you will choose should match the model number with the brand and the model of the unit you have installed.
Easy warnings your main board needs a replacement ASAP
- Your system ceases to operate whatsoever
- There may be flashing code shown directly on the control board
