it's erratic

idk ask someone that works there

The most vulgar failure on any any modern dryer is a thermal fuse. These monitor temps inside & blow (they do not reset) if the dryer exceeds sane operating temps. Some dryers have three, in addition to thermstats that moniter & cycle the heat.
I would recommend trade a professional- the money you might waste changing unneeded parts will pay for a service call.

its got to be the thermal constituent..mine went out and that was the same problem....its a small ceramic piece with a metal probe...they over heat and check and then will not work...call the company repair man and he can replace it, took about 10 mins to replace mine...

Give ten to aplliance tech.

If you are at one's fingertips, you can repair this easily and only pay for the part. If you aren't handy then you should just call a repairman and pay up.

Assuming you are handy, then you call for to remove the front panel of the dryer and look for the combustion chamber. Since it is a gas dryer, follow the gas line until it goes through the gas valve and into a big-hearted tube. Near the gas jet at the opening of the combustion chamber will be an ignitor. It will be a black ceramic looking wire coming out of a chagrined white or tan box. The wire will be about 3 inches long and the box will be about the size of a match box and have two wires coming from it.

Look very closely at the ignitor wire, but do not write of, as it is very fragile. If the ignitor wire is cracked or broken, then this is the part you need to replace. Call the local appliance put back in shops and ask them if they sell repair parts for GE dryers. When you find one that sells GE parts, tell them you need a new ignitor for your special to dryer (have the model number and serial number handy). It will cost $20 to $50.

The old ignitor is quite screwed onto a bracket with a single screw and the wires will unplug from their connection to the wiring harness. Straight unscrew and unplug the old ignitor and put the new one in its place. Be careful with the new ignitor because these can be very fragile and you don't want to have to buy another new one like I did. :)

If the ignitor looks righteousness, then the problem lies elsewhere and will require extensive troubleshooting. Diagrams and parts lists are available at distinct places on-line, like sears.com.
