Will not heat
Obviously make sure the gas valve is open and gas is going to the unit.
Check the inspection port on the lower left of the front panel. Small plastic disc. Remove it and look in the hole while the dryer starts... you will see a glow plug that gets red. Then a click and the burner should light. If it lights but does not stay on the problem is likely with the flame sensor.
If it does not light at all, the valve could be bad.
Send me the results and the make/model and I'll help you solve it...

You have bad coils on your main gas valve . They tend to short (open) after getting warm which cuts off the gas to the burner . After cooling , they will work again for another 5 min until shorting again . Replace the coils (2 in a kit ).
SOURCE: gas dryer maytag MDG 7600 AWW Heats - then shuts off
Check the flame sensor mounted to fire tube, its a rectagle with a glass window, also the coil can be replaced on gas valve if they are weak,
You definitly want to check the exhaust vent and vacume.

Since your hot surface ignitor is glowing, that means it is trying to heat, or that all the temp. switches are good and the timer is sending the signal. First check that there is actually gas pressure to the dryer. But the common problem is the coils on the gas valve. There are two, called the booster/holding coil, and the secondary coil. They are purchased as a set (part #279834 / $20.00) if it is the same as my mdg8600aww model. If that doesn't work, then likely the gas valve itself.
Sometimes those coils will open circuit when they warm up, and close when they cool down, giving you an erratic operation symptom.

Based on your description, you may have a Gas Valve Coil failure. Below is a link, courtesy of www.repairclinic.com, showing the part(s) involved. http://www.repairclinic.com/SSPartDetail.aspx?s=b4a8c237i3479&PartID=3479
More assistance below: You will need your model number to access the information.
Model Number Locator Tip
1. A zero in the model number might be the letter O.
2. A lower case L might be a 1.
3. Some models have 3 digits and a period first, like this 555.66666666
Look for an aluminum tag--or a silver and white adhesive label in the locations illustrated below. The model number may be printed or stamped onto the tag and may be printed in different type sizes. NOTE: There may be partial model numbers on marketing stickers or in the owner's manual. These are often incomplete. For best results use the model number from the tag.

2. Diagnostic tips:
If your dryer doesn't heat, check these:
Igniter
Gas valve coils
Thermal fuse
Igniter
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
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
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.)

Hi,
If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.
if you dryer is gas check out this gas no heat tip....
If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.
check out this electric no heat tip...
