Goodman GMS80453AN Control Board
It is impossible for your furnace or air handler to even be able to function without the main control board installed. The Goodman GMS80453AN control board is made to command everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all together. You must be careful while choosing a new control board because of the many variances of models within certain brands. The selected board should have part numbers that match both the brand and specific model of your Goodman GMS80453AN unit.
Key signs of a barely functioning control board
- There may be flashing code displayed on the control board
- Power to the control board has to be turned off and back on frequently for it to kick in
- The unit cannot do anything period
