Goodman GCVC90704CXAA Control Board
Your system definitely will not run without the main control board in place and connected. The control board is made to command the gas valve, the ignition igniter, all the various sensors as well as the blower all in one unit. Any control board you choose must have a matching part number consistent with both the brand and model of the system you have installed. It is imperative that you select wisely when you choose a control board because of the wide variety of brand and air handler types.
Subtle hints your main board is on its last leg
- When turned on, there is a strange code revealed on the front of the control board
- Entire unit refuses to function properly
- The HVAC system has to be powered down and back up often for the thermostat to kick in
