International Comfort Products PA5524AKA2 Control Board
The control board is designed to oversee the gas valve, the ignition igniter, all the various sensors as well as the blower all at once. Your system definitely will not run at all without the board accurately installed and configured. Be absolutely sure while selecting a replacement due to the many differences between models within certain brands. The board that you will choose is supposed to have a part number that matches both the brand and specific model of air handler system you have.
Subtle cues of a weak primary control board
- Power to the circuit board has to be reset all the time for the thermostat to kick in
- Could be an a numbered error code appearing on the board
- The AC or furnace refuses to do anything period
