Goodman GDH80703AX Ignition Control Board
The main ignition control board may control gas intake, the ignition sequence and the flame sensing circuits. It has been a very important device that some companies have moved to be a standard part of the main board instead of having two separate boards.
Clues to watch for to know your ignition control board will die soon
- HVAC ignition system is unwilling to launch even though it is supposed to
- The initial signal from the primary thermostat does not get to the Goodman control board
- Every other device within the furnace is inspected and turns out to be okay
