You need to type GOODMAN GAS APPLIANCES into you browser to find you local servicecenter. I must tell you that Goodman only sells to authorized service companies in my experience. So you become EgKraft Company.

THE ROLL OUT SWITCH IS LOCATED IN THE BURNER COMPARTMENT MOST CAN BE RESET
SOURCE: Goodman model gmt090-3a vent pressure switch code.
the pressure switch tube is clogged. you can find by looking at the inducer motor which is the small motor towards the top of the furnace ,there will be a rubber hose coming off it going to a round disc with two wires attached to it. remove the hose from the disc and blow thru, if you cant remove the hose from the motor and insert a small paper clip into the barb fitting the hose was connected to until its clear and reconnect the hose . recycle power. you should be good to go.
Testimonial: "Thank you! Very helpfull. It's starting to get cold at night."

It's mounted onto the gas valve. It will be a button or lever that you have to push in or down, depending on the style.

The sequence of events for furnace operation is -
Fan purge for 30-45 seconds. During this time, a pressure switch is actuated by the running of the purge fan, proving the control board the purge fan is running.
After purge and purge prove, the hot surface ignition and or spark begins. After a few second delay, the gas valve will open. The control board then monitors for flame prove through another sensor located near the burners. If there is no flame within 3-5 seconds, the gas valve closes. It will repeat this process, usually 3 times, before it shuts the system down, which requires a power down of the system to reset.
I have seen trash get into the hose between the purge blower and the purge switch. But you could be having other problems.
