Wiring question

[Skia]

our 30 year old clothes dryer shit the bed this morning and won't start. I have a newer dryer that we have in the shop that was Haleys just sitting. The old one has a 3 wire plug and the new one has a 4 wire. Looks like 3 power and a green external ground. Can I just replace the 4 wire with the 3 wire with no issues?

Take the 3 wire plug off the old dryer. Install it on the new dryer.

Follow the wiring instructions for the three wire setup. There's jumpers and shit.

Lot easier than wiring up a new 4 prong outlet all the way back to the panel.

This sounds correct. I'm not an electrician, but I remember when I was selling appliances at Sears the dryers came with no cord attached. You bought the cord that fit your wall receptacle separately and then it was installed on the dryer by the customer or delivery man.

3 wire = two hot legs and ground
4 wire = two hot legs, ground, and neutral

Or you could install one of the Solar powered dryers:

I have no instructions

Technically speaking neutral and ground are the same thing, just that the metal frame of the drier has it's own line going back to the main breaker box, I dunno why they went ape shit with this 4th wire, as it goes to the same spot as the neutral......in the box, that is.....now from the box you have a ~10 ga wire to your grounding rod outside the house, which makes this modern 4 wire crap silly, really.....

so to keep the red/black wires hooked up right, and the neutral hooked to the major current, and to ground the frame of the machine to the neutral but good, at the drier itself, and you be fine....

typical .gov trying to make the world PURRfect and in reality making something simple, stupid......:issues:

:seasix: That's what we used today.

To in Mr.Vette the answer- connect the neutral and equipment ground together in the machine. You should have red/black/green.

Why seperate the neutral from equipment ground ? Neutral is a current carrying conductor. The dryer's drum motor is 120V so you need a neutral. The equipment ground is used for circuit protection. But, with older homes, they have to have a way to connect to those systems- so you tie the neutral and ground together.

I could have gotten really confusing and use bonded conductor and bonding conductor. :lol:

4 wire = two hot legs, ground, and neutral

Yep, just wire up the 3 wire cord and you're good to go

[Skia]

So the answer is to wire the 3 wire to the red white and black and don't worry about where the green ground is?

No......the answer is to jump the white and green together at the point you put the old plug wire in the machine. Wire the old plug wire to red, black and green. You HAVE to jump them together for the dryer to work and for circuit protection.

No snowballing here man.....I dun sum 'lecrikals over the decades....I too can smoke wires.....:seasix::hurray:

WHAT???

As Kevin said, 3-prong - 2 hots & ground. 4 Prong - 2 hots, neutral, & ground

That tells me that there's something in the new dryer that runs on 110 which needs one power leg and neutral. Odds are, there's an unused neutral in the outlet box in the wall that can be properly hooked up to a 4-prong outlet. Might be best to hire a pro for this if there are questions though.

What kind of dryer is it? Electric? Gas? The motor may be 110, but if electric, heating source may use 220. Did not read any of that referenced except the motor.

Electric 220 I think. The old one was 220 single phase.

I not bought any of that since Elementary skool.....

:rofl:

Just for the knowing, all residential wiring is single phase, in reality, but if you have to get techy, call it two phase....

but then you have to understand power generation and 3 phase and how to get one phase then two phase out of 3 phase....

which topic can get a bit phazzy for the Cat a tonic among us......
