This almost indicates the solenoid coils on the gas valve are bad and not holding the valve open for gas to flow through. Replace both of them - part numbers are 694539 $31.00 and 694540 $ 33.00 Open the door and remove the screws on the door hinge and on opposite side -(the plastic fillers) and remove the front ( no- the door won't fall off but it will be "loose") move it to the side and leave wires connected . See the gas valve - on top of the valve are the solenoids with wire connectors on them . Get the parts first and this will help you see what I'm referring to . Thanks for using justanswer.
