Goodman GCH91155DX Control Board
The control board is created to operate the gas valve, the ignition igniter, all the various sensors and the blower all at once. Your system definitely will not run without the control board properly connected to the unit. The board you select should match both the brand and model of the system you have installed. You should always be careful when you are deciding on a replacement because of the wide variety of HVAC systems.
Easy warnings your main board should be replaced
- Power to the circuit board has to be turned off and back on habitually for it to run correctly
- The entire system is unwilling to go properly
- There is a strange code appearing on the control board
