International Comfort Products GUM Control Board
The International Comfort Products GUM control board is made to oversee the gas valve, the igniter, the flame sensor as well as the blower all together. The entire heating and cooling system will not run without the board in place and connected. You should always be careful when you decide to replace your control board due to variances between certain brands. The board you select should have part numbers that match both the brand and specific model of your particular system.
