Question about Maytag Dryers
Firstly, ascertain that you have made a positive heat selection on the control panel temperature switch, If available.
Below are some links, courtesy of www.repairclinic.com, that will assist you in diagnosing/repair of your dryer. You may have to enter your model number in the search box to access some of the information.
Below is a parts breakdown/disassembly procedure for your dryer.
If your dryer doesn't heat, check these:
Gas valve coils
Igniter http://www.repairclinic.com/SSPartDetail.aspx?s=t-dg312-%3d%3di3018&PartID=3018 Modern gas dryers use an electric igniter to ignite the gas from the gas valve. When it's working properly, the igniter glows bright orange. When it burns out, the dryer tumbles but there's no heat because the gas can't ignite. When the igniter burns out, you need to replace it. If the igniter is held by a tension bracket, you very well may need to replace the bracket too.
The igniter is inside the dryer housing, near the bottom front, usually in a cone-shaped metal tube (the force cone). It's about 2 inches long. It's mounted to the far end of the burner tube, and it has two wires attached to it--or to the tension bracket, if there is one.
Gas valve coils http://www.repairclinic.com/SSPartDetail.aspx?s=t-dg312-%3d%3di3479&PartID=3479 Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite. Because it's often difficult to properly test the coils, it's usually best to replace both (all) of them at the same time.
Thermal fuse http://www.repairclinic.com/SSPartDetail.aspx?s=t-dg312-%3d%3di483890&PartID=483890 On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing.
If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)
Other components that could keep it from drying.
Washer not spinning dry enough
Make certain that unrestricted airflow is available.
Blower: must be tightly attached to motor shaft.
