My gas dryer will not blow air

the thermocouple ot high heat limiter ====the thermocouple when going bad -or not properly on bracket will shut the gas valve off --same with high heat limiter ---before checking these parts feel the air coming out if feels restricted clean the vent tube under the lint trap filter can use a vacuum from front and rear exhaust tube

If this is the electric version then after 15 years you probably need a new heating element, they are not difficult to install and are not terribly expensive as a DIY project.

replace the blower belt and it will blow air from the dryer

I would look for air restrictions. Improper air flow will cause overheating. This will cause the components to shut down prematurely.
If the gas fails to come back on then the gas coils are weak and overheating becoming intermittent

When you say 220 gas dryer I'm not sure what you mean. If it's 220V then it should be an electric dryer, not a gas dryer. Troubleshooting is totally different between gas and electric. If it's electric (large 30A 220V plug) then good chance heating element(s) have gone bad. You can look up parts on www.searspartsdirect.com Have your complete model number. IF it's gas, it may be the pilot ignition has failed

This sounds like the dryer coils are failing. They tend to fail as they heat up. Here is a link that should help http://appliancehelponline.com/gdryertroublevideo.html

Hi, If you have a gas dryer.
The most common problem with a gas and no heat is the ignitor going bad...

Here is a tip that I wrote about that problem...

Check for a blown thermal fuse or a faulty heating element. Both components can be tested using a multimeter or ohmmeter. Check for continuity. A lack of continuity indicates a faulty component. The thermal fuse is about an inch long and is located just inside the rear of the dryer and is usually attached to or near the exhaust duct. Hope this helped and best wishes.

The following link explains how to troubleshoot and dryer "no heat" problem and the common causes:

Read through the link thoroughly, paying particular attention to the section that discusses proper ventilation. Most dryer heat related problems are caused by insufficient air flow which, in turn, causes the dryer to overheat to failure. More commonly, the Thermal Cut-Off (TCO) fails. You will need to check all the components mentioned in order to be sure. If you haven't had your dryer ventilation cleaned or inspected in a while, now would be a good time to do so. Failure to correct any potential existing problems, can cause premature failure of any parts you replace.

If you have questions, or require additional assistance, please let me know, so I can provide you with a viable solution. i hope this helps you.
