Goodman GHS80453AXCA Control Board
The control board is made to oversee the gas valve, the ignition igniter, the flame sensor and the blower all together. It is impossible for your furnace or air handler to even function unless the control board is in place and connected. The proper control board should be compatible with both the brand and specific model of HVAC system. It is imperative that you select wisely when you choose a replacement due to so many small differences in models within certain brands.
Key clues of a defective main circuit board
- System has an error code suddenly appearing somewhere on the board
- The board has to be powered down and back up more often than not for the system to continue working
- The AC or furnace is unable to go whatsoever
