How do I test for bad thermastat or heating element on GE dryer
I have GE dryer DBVH512EFO ww. It appears the heating element is coming on as I can see the red glow, but the clothes are not getting dry. I am having to continually add time. I need to isolate the problem and want to test the thermostats and the heating element. I have replaced heating elements on older style dryers, but the heating element for this dryer is very expensive so I wanted to determine if it is a thermostat or element.
I am a huge DIYer and pretty good with electricity. I disassembled the dryer last weekend and did not detect any major lint build up. I will do almost anything to avoid calling a service repairman, but I am getting close...

Re: How do I test for bad thermastat or heating element...
Well the fact that hte heating elemnt is glowing tells me that all the thermstats are working, i would check for a blockage/restriction in the venting. looking at te diag, its possible that only 1 of the 2 coils for the heate are actually going on, check the coils for continuity( may be a small break that separates when gets hot)

check the thermal cut-off. it's on the element housing. when that goes out, the element will not heat up. good luck :) just check for continuity. it comes in a package with a new thermastat. replace both of them.
Clogged lint filter, exhaust vent or outlet would reduce air flow but there would be some heating unless a high limit safety switch has tripped and needs to be reset. There may be aa air flow switch that prevents the element from heating up if no air is flowing. Blower wheel may have broken off at connection to motor shaft.
Only 2 things left. A bad wire or bad control board. Remove the rear panel. Set the range to bake,check power at the element terminals with a voltmeter. Ifyou do not have 220 volts at the element replace the ERC.(clock).
I am sorry to hear this, my name is Marc White, i am self employed and it seems as though you have a bad timer, bad timer will cause the timer not to go to the off position and blow your fuse......change your timer..
The exhaust hose in the back will not affect whether the dryer will heat. The hose just removes the used hot air to a place outside your house. I assume dryer drum spins, but you get no heat. If the dryer has gotten a few years of use, I suspect that the heating element has gone bad. Have you noticed that it has taken longer and longer to dry clothes than it used to? If so, most probably the element is bad. The element is not unlike a heating element in an electric stove, and is housed in a duct inside the dryer.
