I have seen acouple of these dryer were the thermal fuse would open up and would reset which it is not support to do.Also check power at back of dryer for 240 volt red to black and red to white for 120 volts and black to white for 120 volts.do this voltage check when dryer stops.If proper voltage then problem with dryer.Check that thermal fuse with meter or jump it out.Try wiggling timer knob when dryer is running to see if dryer will stop if so timer bad.

This reminds me of a gas dryer that was tripping the breaker after a few minutes.  Played with it for a couple minutes, and concluded that it was the breaker.  Plugged it into a different breaker circuit with an extension cord, and it stayed running.

Customer told me his washer on the same circuit didn't trip the breaker, so it must be the dryer.  Turned out, for the breaker to act up, the breaker needed a higher current, for an extended period.  The washer didn't draw enough current to trip the breaker unless it ran the final high speed spin cycle.  In the end, it did trip the breaker.  They had the washer set on delicate spin.  Go figure.

Sorry, I've been out of town for last few days...

AJ: I do have the auto/timed cycles and the problem exists with both

dab147315: I tried wiggling the timer knob but the dryer didn't stop.

I read about breakers; is there an internal breaker in the dryer or are we talking about the breaker in my main electric box?

I guess my next step is to get a multimeter,

Thanks all for your help!

So with my new multimeter :), I did a few readings:

hot wires/hot wire + neutral = 240/119 while dryer is not running
hot wires/hot wire + neutral = 238/119 while dryer is running
hot wires/hot wire + neutral = 234/116 while dryer is running and element is on

Is this normal, the little drop in voltage when it's on? I did those readings directly at the plug... not sure how to do it at the back of the dryer; the wire is connected to the dryer in white plastic plugs (see pic). Do I need jumper cables or do I do the reading directly at the timer?

I did a resistance test at the thermal fuse, door switch and the hi-limit with dryer disconnected and got a 0.3

Today, the dryer for some reason is working pretty well. I was trying to get a reading when it stops but it didn't. In 2-3 hours of running, it stopped once - I ran to it and took a reading at the plug and it was fine. This was 15 secs max after it stopped. But then I pressed the start button, maybe another 15 secs later and the dryer started again. As far as I know, I had to wait a few minutes before I could restart it... weird. Do you guys sometime get problems that go away on their own? I didn't think so.

If you can give me a hint on how to take a reading from the back, I'll post the result once the dryer starts acting up again,

Thanks,

The picture of the wire in back of dryer is wired different then in U.S.A.I would unplug the black wires,red wire and white wires in the picture you sent and look if see any kind of burnt wires on the white connectors.Odds are you have a loose connection or bad circuit breaker.But that thermal fuse can open up and close again.Which i seen it do only maybe on two of the same dryers in 30 years in business .Its something to keep in mind.

I didn't see any burnt marks on the connectors. But those plugs were very difficult to disconnect - except one which was too easy; this might be the loose connection you've been mentioning... I'll check if this fixes it. Thanks dab for all your help.

Check the Non resetable High Limit Thermo on you heating element ( it should be the top one). Its not making good contact. Let me know if that is  it. It was the problem for me on a GE dryer for me.
I been doing this too long...

The high limit thermostat if it opens will not make dryer stop running only shut off heat .He has said as posted dryer stops and then sometimes has to cool down and pushes start button and then it will run again for a while.

Sorry Dab, I had a brain freeze or something about the hi limit thermo.  Dab is right its a loose connection somewhere that's heating up.
