International Comfort Products PGMD42G0604 Control Board
The International Comfort Products PGMD42G0604 control board is designed to oversee everything including the gas valve, the igniter, all the sensors as well as the blower all together. The HVAC system will be unable to function without the main control board configured and seated properly. The board you select should be compatible with both the brand and specific model of air handler system you have. It is imperative that you select wisely when choosing a control board due to the vast differences in brand and air handler types.
