hope this helps. my gas service was disconnected for servicing a couple of days. My daughter did not know this,she put a load in. as she did this she heard 2 pops from the dryer. Now it doesn't get hot. I was told to look through the little sight hole to see if i see any glow, i didn't. I've researched this to find out it could be a number of issues. This just confuses me. Is this a common repair? What could it be? I don't want to start replacing parts without narrowing it down. Thanks for any feed back.

Ok, another update. already changed the ignitor,which glows now. just finished replacing the thermal fuse and the 2 little solinoids on the burner. Turned the gas back on and still no heat or flame. am i missing something? so far i've replaced everything this forum says. thank God it wasn't expensive. Can someone please put me in the right direction? Going to bed now with an angry wife. Thanks for any feedback.

Are you sure the gas is on to the dryer? Turn the gas supply line valve off then unhook the gas line then turn on the gas supply line valve and see if gas comes out, thats the only thing it could be.

Lets check your flame sensor.

Ok, make sure your dryer is unplugged, then take the wires off the flame sensor and check that for continuity.

Here's the flame sensor, it mounts on the side of your gas burner tube:
Manufacturer part#338906 is RepairClinic item#2681

When I bought the other parts at the repair shop, i took that part and they tested and said it as good. but after watching that video, I'm going to have to borrow one of those testers today and test it myself. At this point I hope that it is bad. I'll let you know. Thanks for your help so far Jake.

Ok, just tested the flame sensor. It has continuity, but it fluctuates between 5 and 10 ohms. doesn't go to zero. does that mean it's bad or going bad? should it still make the burner go on?

k, retested flame sensor. looks in good shape. Have a cheap tester, wasn't holding the leads tightly. proceeded to look for messed up wiring. found that the white lead was burned through from the burner orfice. fixed that and still the same thing. no heat. Thought maybe I messed up the thermo fuse. tested it and still good. I don't know where to go next. At a complete loss. Why isn't anyone else have this problem? If you guys help me get this fixed, you are Gods to me. I could just buy another one but i'm on a mission now. This thing won't beat me. sorry just gotta laugh now. Appreciate any suggestions.

I understand. How about that part that's underneath the thermo fuse? the one with the 4 wires to it? could that maybe a problem? how do I test that?

No, that wouldn't be the problem, thats the cycling thermostat, if that was bad the igniter won't even glow.

Just wanted to come here and give last update. I got it fixed. turns out the thermo switch which controls the solinoids to the burner was stuck. did a little tap with the end of my screwdriver and wham, got gas and flame. I just want to say thanks Jake for the responses and helping me narrow this down. I recommend this sight to anybody with appliance problems. Thanks again.

You mean the thermal fuse? I don't see a thermal switch on your model.

But we already tested the flame sensor.:)

If the contacts inside the flame sensor are just sticking at times, then it will eventually do it again until you replace it.:)
