GE AZ75H12DACM1 Control Board
Your furnace or AC will not run at all without the main control board installed. The control board is designed to direct everything including the gas valve, the igniter, all the sensors as well as the blower all at once. The control board you choose will have a matching part number that will fit in the brand and the model of the unit you have installed. You must be sure while selecting a replacement because of the wide variety of HVAC systems.
Signs your main board is on its last leg
- The entire system needs to be reset habitually for the thermostat to kick in
- Air conditioning or heating system will not do anything at all
- Could be an a flashing error code appearing on the board
