International Comfort Products GPSM48H120F Control Board
The control board is created to control everything including the gas valve, the ignition igniter, all the various sensors as well as the air circulator all together. The system will cease to be able to function unless this important circuit board is installed as it should be according to the manufacturer. The board you select must have a matching part number consistent with both the brand and model of the unit you have installed. Be absolutely sure when you decide to replace your control board due to variances between models within certain brands.
