Goodman GSX160421 Control Board
The control board is created to command the gas valve, the igniter, most sensors and the blower all in one unit. Your furnace or AC will not operate lest the main control board is accurately installed and configured. The control board you choose should match both the make and model of furnace or air handler you have. You must do some research when choosing a control board because of the diversity of certain brands.
Easy warnings of a barely functioning main board
- Entire unit is unwilling to function properly
- Could be an a strange code instantly appearing on the board
- The power to the system has to be turned off and back on quite a lot for it to kick in
