International Comfort Products PGAD Control Board
The control board is constructed to control everything including the gas valve, the ignition igniter, the flame sensor as well as the blower all together. The HVAC system will be unable to run at all lest the circuit board is in its proper place and configured for your unit. A matching board is supposed to have a part number that matches the brand and the model of the system you have installed. It is of utmost importance while picking a new replacement board because of the diversity of certain brands.
Major indications your primary control board has little life left
- The furnace or AC is unable to work whatsoever
- The entire system has to be turned off and back on all the time in order to run
- There is a numbered error code appearing on the board
