Having an issuse with my goodman furnace. Fan turns on, Ignitor turns red, flame comes on, and then goes out then blower motor comes on. Repeats 2 or 3 times and stops. The led is a steady red. I have replaced the circuit board, flame sensor, flame sensor wire, and the 24v transformer chassis ground wire. Also cleaned ever contact I could find.

Check the ground wire connection to furnace
