Does anyone here know about gas dryers?

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.

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

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

Great description. Thanks! =^..^=
