Goodman GMS81155CN Control Board
The control board is designed to control the gas valve, the igniter, all the various sensors and the blower all at once. The system will cease to run at all unless this board is in place and connected. Any control board you choose will need to pair with the part number from both the make and model of your Goodman GMS81155CN unit. Be very careful when you decide to replace your control board because of the wide variety of heating and cooling systems.
Some warnings to watch for in a failing primary control board
- When turned on, there is some sort of error code directly on the board
- The AC or furnace does not initialize period
- The system has to be reset frequently for it to kick in
