First I unplugged the dryer, then removed the back panel, this exposed most all of the wiring and I could see the heater coils. Not knowing what the problem was I started looking at the coils and could not see any broken parts. So then checked the thermal fuse for continuity I removed the two wires from it with a small pair of

Read moreneedle nose pliers, it was held in place by two screws, once they were removed the fuse came out easily, I checked continuity with a volt meter placing the meter on X1 Ohms and could not get a reading. I replaced with a new one and put it all back together the way I took it apart. Then I plugged it in and it worked first time, I now have warm dry clothes.
Cleaning the lint out of the whole machine took quite a bit of time--it was everywhere. Underneath the lint trap was a collection that ultimately ruined the thermal fuse where it restricted the air flow considerably.
Ascertaining the problem was the most time consuming part.
The actual repair was quite simple and did

First removed front and drum to check gas valve and igniter. No gas, no ignition. Checked power to devices; none (check hot line to ground, not to neutral.). Removed back of control panel looking for a relay or something. Found none, but did find a wiring diagram. That is where the site really came in handy. Studied wiring diagram t

Tested each part with meter, again going to ground and not across the device. Of course, the final device before the gas valve, a one time thermal fuse, was the bad part. At first assumed just a bad part. Later wondered if fuse did it's job and another part was bad. Ordered and installed new thermostat just in case. Put everything together after a complete cleaning and everything is fine so far. Not a particularly hard job because I had the wiring diagram and access to parts select site. Would have been much harder without them. Took a long time because almost the entire dryer had to come apart. But it got a good cleaning because of it and found a couple of bucks in change to help offset the cost. Can't imagine what a service call would have cost.
