Goodman GMH Control Board
The entire heating and cooling system will not run at all lest the main control board is installed as it should be according to the manufacturer. The Goodman GMH control board is created to regulate everything including the gas valve, the igniter, most sensors and the blower all at once. You must be sure when you are choosing a replacement board because of the diversity of models and types. The control board you choose should match the model number with both the brand and model of air handler system you have.
