Mitsubishi MSH-12NV Control Board
Your air handler will be unable to be able to function lest the main control board is configured and seated properly. The control board is designed to command the gas valve, the igniter, all the sensors and the blower all at once. A matching board should have part numbers that match both the make and model of your particular system. Be very careful when you are deciding on a replacement because of the wide variety of HVAC systems.
