Question about Goodman GMS807034ANA Heater
This can be due to a dirty flame sensor or a high limit switch tripping. Clean the flame sensor first, this is a metal rod on the opposite side of the igniter, take steel wool and scrub it, then reinstall. If this does not work then the limit switch is tripping due to dirty filter, dirty blower wheel, weak blower motor. Aything that restricts airflow will cause the limit switch to trip.

SOURCE: pressure switch stuck open
It most likely is not stuck..... It is just doing its job. You "most likely" have over problems. To "properly" diagnos this problem you will need a manehelic gauge. You can have a wide variety of problems from as simple as a blocked or disconnected vacum hose to a lifetheatening problem.... a blocked flue pipe or a bad heatexchanger.

In the burner compartment opposite of the ignitor is the flame sensor. seems to be dirty. one screw holds it in. Remove and clean with a wire brush.

I cleaned the sensor that was at the the right further most burner on my Goodman and it worked. got the answer to my problem here at fixya. My burner flame only lasted 5 secs before it shut off. Thanks to all who took the time to send me a response.
