Question about Goodman GMS90703BXA Heater
The venter blower, igniter, gas, flame all go on as they should. Then about 5 sec. after the igniter turns off the gas shuts off. I changed the flame sensor thinking that was the problem, but still the same. Any advice welcomed
Clean the sensor with a piece of fine sand paper. It gets a coating on it after a few years of service. I had my cleaned for $160, it took five minutes.

Check the pressure sensor. I tapped on mine a few times, removed the hose and checked it for blockage and replaced. It has been working fine since. I do have a new sensor on order.

Make sure you trace the wire to the flame sensor back to the board and see that it is still connected.
