Goodman GMH80904BN Control Board
Most systems will not function without the control board in place and connected. The control board is made to oversee the gas valve, the igniter, all the various sensors and the blower all at once. The control board picked must be compatible with both the make and model of the unit in question. It is imperative that you select wisely while choosing a new control board due to the vast differences in certain brands.
Key clues of a laboring control board
- The HVAC system is not able to do anything properly
- Power to the control board has to be turned off and back on many times a week for the furnace or AC to kick on
- Could be an flashing code randomly appearing on the front of the control board
