Does anyone here know about gas dryers?

Re: Does anyone here know about gas dryers?

Well I think I fixed something. The gas coils arrived today and installed in about 10 minutes (I've had some practice). It's dried 3 loads of laundry all the way through.

Here's the point I don't get: The gas coil is just a solenoid. A coil of copper wire around a ferrous core. Which part is intermittent? The coil either has a circuit or it doesn't. The ferrous core is the same one, not replaced, so theoretically if it was magnetized it would still be magnetized.

Regardless, it's fixed for $30USD. I'm happy. =^..^=

Going back to the pre semiconductor era when the world quite happily ran on relays I was a telecom tech and worked in a telephone exchange surrounded tens of thousands of solenoids and relays that rattled and clacked as they switched your telephone call through. Spent a lot of time replacing faulty relay windings that would sometimes work then sometimes wouldn't. The theory was that if the relay was energised for too long it would heat up and expand and strangle its self. If there was a bad joint or a break in the wire there would be a circuit when it was cold but would open circuit its self as it warmed up.
I hope that helps

Dont joke. I just constructed a HHO generator that work much better than expected. Some safty issuse conserns, because you can loose your facial hair and your hearing if something goes wrong. Also not easy to burn that stuff off without a bang!

But can power a gas generator! Next move its going on my car.


The energy crisis and power cost in ZA makes a electric dryer just to expensive to run.

Yer played around with the HHO gear a few years ago. Lots of fun.
We're getting ripped off with Solar+Grid power here so I built myself a Kapagen Energy generator.
Only getting 97% effieciency which I thought was not too bad for first attempt.

Anyway we should probably move this topic to another post.

Yes I remember the old step by step relay central offices. My last six months of active duty in the Army was spent at Ft. Ord, Ca as a telephone installer assistant. That meant that I got to go out with a civilian installer and do trouble shooting, repair and installation. That was just about the time the first cross bar system were starting to be used.

I just hope the person responsible isn't a copier tech!

Just saw this pic on the internet the same day as the post.

I do have a warped sense of humor, but it was f'n funny.

I'd guess it might be that one of the wires leading into the gas coil was broken thanks to metal fatigue just enough that it occasionally lost the connection. Years ago, Riso's pressure solenoid was rather famous for that problem.
Unless the wires leading in to the gas coil weren't part of it, in which case the proceeding is entirely wrong.
I suppose it could also be a failure of the insulation on the windings of the coil inside of the solenoid. I don't know if you've ever taken a solenoid apart to see the windings, but I did back in the day and the insulation on that wire was pretty thin from what I saw then.
Those are just guesses though.

Show me a Strowger switch and I go all weak at the knees!! well at least I knew how it worked.

Great description. Thanks! =^..^=
