International Comfort Products GPFM48H080F Control Board
Your system definitely will not operate whatsoever lest the circuit board is in place and connected. The control board is created to direct everything including the gas valve, the igniter, all the sensors as well as the blower all at once. Be absolutely sure when you are choosing a replacement board because of the wide variety of models within certain brands. The proper control board must have a matching part number consistent with both the make and model of furnace or air handler you have.
What red flags are there that my control board is in need of a replacement?
- The unit will not go whatsoever
- Everything has to be powered down and back up more often than not in order to continue running
- When turned on, there is a fault code being shown on the board
