Have an electric dryer (110.87562601) that seems to be throwing circuit breakers only after running hotter or longer periods. 220v plug is the 3 prong (not 4) kind. I'd ordinarily start to wonder if the wiring run has used too thin a gauge or some other fault in the wiring. Has been hard to nail down if there are any other things to the pattern and it's not happening often enough which makes it even harder to observe.

But today while running a very wet blanket (not dripping wet) through a heavy automatic ("jeans", temperature is "medium hot) cycle it started at a normal 70-some-odd minutes and then I went down to check on the driver and even though the blanket was nearly dry it said time remaining was "99" (minutes). So, I'm wondering if there's actually some kind of thermostat problem (perhaps intermittent) that is causing the heating mechanism to go way beyond where it should, drawing too much on the wires and only then heating household wires enough to throw the breaker.

Ideas?

Many thanks.

... Ideas?

1) thin wire wouldn't cause it
2) Thermostat wouldn't cause it
3) the House Circuit Breaker could be weak
OR the Dryer Drum Motor could be drawing too much current when hot.
Remove the Belt and try turning the Motor Shaft by hand.
Does it turn easily, smoothly ?

Thx that helps. I'll try to report back on the drum. I have a home warranty that covers electrical wiring (only de minimus) and of course appliances, so your input helps. Trying to figure out if there's something simple that's cheaper than the $60 cap I pay under the warranty for the service call. Think I can pull a panel(s) and test the motor w/o belt attached.

. I had this a few years ago. Dryer would often throw the breaker. An electrician had been out and said the breaker was fine, so I spent hours monkeying around with the dryer. Finally I'd start the cycle and run down and hear a crackling noise from the breaker panel. Then I got the client to start it while I was at the panel.

. Turns out it was the breaker. There wasn't one of the same amperage in the panel to test it out on, so the only alternative was a trip to the hardware store for a new breaker.

. Anyway, try listening at the breaker panel. If there is another breaker of the same amperage you can swap out, and know how to be safe doing so, try that.

. Intermittent problems are a pain to diagnose. I doubt the heater is overheating. First there are safety thermostats that would blow. Second, it still draws the same amount of current no matter what.

. I'm assuming the 99 is a coincidence or anomaly, here, but I could be wrong.
