Goodman GMS80704BN Control Board
The control board is designed to oversee the gas valve, the ignition igniter, all the various sensors and the blower all in one unit. Your furnace or AC will not operate whatsoever unless this important circuit board is in place and connected. The control board picked must have a matching part number consistent with both the make and model of air handler system you have. Be absolutely sure upon picking a replacement board due to the many differences between particular brands and their models.
Simple signals your Goodman control board is failing
- The unit ceases to initialize correctly
- The board has to be powered down and back up habitually for it to run
- There seems to be a strange type of error code directly on the circuit board
