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...

The model number you gave is for a gas dryer.
You will not find a thermal fuse in this dryer.
Your problem with no heat most likely lies in the gas valve or its subcomponents like the thermistor/flame sensor or igniter/glow coil.

Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

I'll email you a few pages out of a service manual for a WPGT9360 (closest I could find to your model number) hope this helps.

You have a bad blower motor. Best to call GE Factory Service to repair as there is probably still some kind of warranty on at least the part and it is easy for us (GE Techs) to replace but not easy if you have never replaced one. 30 minute job for me to do... GE 1-800-432-2737

your blower motor is probably not working. enter the troubleshooting mode by pressing and holding my cycles and help at the same time for 3 seconds. this will tell you the problem. if blower is not getting up to speed you'll have to replace it.

You didn't state whether or not you were getting an error code. On this model if the blower motor exceeds 3000 rpms for one minute the dryer will stop. Usually this is caused by a clogged or pinched vent hose or vent itself. Check this out first. You can find the tech sheet under the consol. I believe it unscrews from the back and lifts up. This will give you detailed info on how to enter the diagnostic mode. If you cannot find the tech sheet, post back and the cat here will walk you through it. Catriver..post back.
