Goodman GMH81155CN Control Board
The Goodman GMH81155CN control board is designed to oversee everything including the gas valve, the igniter, the flame sensor as well as the air circulator all in one unit. The entire heating and cooling system will not run unless the control board is in place and connected. The correct control board will have a part number that will match both the brand and model of air handler system you have. You must do some research while selecting a replacement due to the vast differences in models within certain brands.
How do you know if your primary control board needs replacing?
- Power to the circuit board has to be reset frequently for everything to run again
- When turned on, there is some sort of error code shown directly on the control board
- The furnace or AC is unwilling to run at all
