Electric dryers are 240 volt. You must have a 30 amp 240v receptacle to plug it into. The cord on the dryer must have a compatible plug.
The circuit should not be shared with anything else, and should be protected with a 2-pole 30 amp circuit breaker.

It is possible for only one side of a 2-pole breaker to pop. When that happens one of the "hot" terminals would be dead and would account for the weird voltage readings you're getting which are just stray voltages from the one good side bleeding back. So Check your breaker first. You should get 120v on each terminal of the breaker and 240v between them. The cable leading from it should be 3-wire (red, black, white). It may, or may not, also have a seperate (bare) ground wire.

Then check voltages at the receptacle. You should get 120v between each hot side and the neutral, and 240v between the two hot terminals. If not, then check the wiring connections at the breaker and at the receptacle. Switch off the main breaker (or pull the disconnect) before doing that.

If voltages OK at the receptacle, but not at the control board then replace the power cord.

The ground wire should be fastened to a cold water pipe with a clamp designed for that purpose unless your power cord and receptacle have a separate (4th) terminal for the ground.

    I saw a video of someone connecting the green and yellow ground wire to the middle white(N) wire. my wire however is not white is yellow. So what piece exactly is the dryers breaker how do i switch it back?

    Connecting the ground wire to the neutral is not only illegal, it's dangerous. Don't do it! The term "breaker" refers to the circuit breaker in your service entrance (main electrical) panel. Judging by your comments, I'd highly suggest you get an experienced electrician to assist you.

    7well heres the thing. I have the dryer and im going to fix it. if you cant answer my question help someone else. if your best advice consists of telling me to hire a professional then i dont desire any further "intellect" from you. as per the illegal, i didnt do this i was confused due to bad info online. i have checked all mentioned things and my problem remains the same (this is after i took apart every piece of the dryer and back together unharmed and unshocked.) i am getting a voltage reading between l1 and l2 @ about 30 what is causing this? the dryer i got when i got it had a wire that obviously went to something else attached to the ground (green/yellow wire) and it was about 3 or 4 ft. hangin off the dryer

    Your poor command of the language, and thinking that the "breaker" was inside the dryer were good clues that you weren't qualified to do this job, nor to understand the instructions given. It was clear that any further details given by me might cause you to harm yourself. I'd rather see you mad at me, than dead from electrocution. The text in my first post was more than sufficient for a competent handyman to check a 240v dryer circuit.

SOURCE: four prong plug to three prong plug

Kalola,
You can if you want to, but it's not generally necessary. Here's a picture of a 3 prong configuration with a ground strap...
df8caf5.jpg

That green wire with the yellow stripe is a ground and it is most definitely connected to the cabinet somewhere. So it will serve as the ground strap (in the above picture).

Here's the thing... say you were going from a 3 prong to a 4 prong. That is, the dryer was originally "designed" for a 3 prong. This means you'd have to "retrofit" it a bit. Take a look at this pic... ( I made this for someone else, so please disregard my somewhat hostile remarks, OK?)
22c744f.jpg

The ground strap has been removed and has been replaced by the ground to the frame. Yours probably does NOT have a ground strap, though... yours uses that Green/Yellow wire for frame ground.

All of that to say this. Don't lose sleep over it. Ya done good.

4-prong to 3-prong Power Cord Conversion.


On a 4-prong power cord you have 2 hot wires, one neutral wire, and one ground wire. On a three prong cord, you have 2 hot wires and one neutral/ground wire. The difference is the on four prong the neutral wire goes to electrical neutral bus in the breaker panel and the ground wire goes to the ground bus in the breaker panel. Since the neutral and ground buses, although separate, both go to physical ground, on a three-wire setup, you are just putting the neutral and ground wire together, Most dryers actually have a place at the pigtail connection to do just that.

Or all blower motors on electric kenmore 80 series 220 or 110 current


Speaking of these United States, here's how that goes.
In this country, dryers are called 220, but they are really 110 twice!
So, on the back of the dryer is a plug with 3 or 4 prongs.
( hope you can get this from my description. )
On a 3 prong plug, the two "slanted" prongs are each hooked to 110 volt p service.
The "L" shaped prong is a ground.

If you have a 4 pronged plug, the two flat straight prongs are 110 volt each, and the "L" shaped and the round prong are both grounded.

FYI: Each of the 110 volt wires has a different function. One powers the motor, the other the heating element.
Be Blessed.

Good day,
Actually nothing. The center wire in the three prong setup works as both the ground and neutral.

I have used tedx640eq0 whirlpool dryer. Just moved into a new apartment that had a 3 prong plug. I connected the 2 hot's and put the ground on one of the ground terminals at the new 4 prong socket that I...


The reason for the 4-wire plug/socket system is that in the older 3-wire units, cabinet 'ground' was actually 'neutral' carrying current for the 115 volt parts of the dryer, while the two 'hots' were supplying 230 volt power for the heater and motor. This allowed a voltage difference between the dryer cabinet and true ground. How did you wire 3-wires (coming from the apartment electrical panel) into the 4-wire dryer socket? Dryer cabinet ground should go to true ground at the electrical panel, and dryer neutral should go to electrical panel neutral. Did Whirlpool violate the separation of 'neutral' and 'ground' when the machine was made (did the timer neutral connection go to cabinet ground instead of machine neutral or is the timer motor stuck)? Your dilemma would be answered by having the apartment owner hire a licensed electrician to upgrade the dryer service to 4-wire specifications. The ground to neutral connection you mentioned may make it work, but you will wind up with the 'hot' cabinet condition that the 4-wire setup was supposed to alleviate. Hope some of this helps!

Also on a wing here, but there is a reason for the 4 prong. 2 prongs do control and other 2 supply power to elements. Have seen a simila situation before. Had to use 2 back to back transformers to get drier to function.

Changing from a 3 prong to a four prong


grasshopper_2.gifWiring in a new power cord for your electric dryer? Upgrading your electric dryer outlet from the old three-prong to the new four-prong outlet? Well, grab hold of those two large lumps at the base of your spinal cord and let's romp through the wild and wacky world of dryer cords and outlets.

tn_3cord_dryer_terminal.jpgtn_4cord_dryer_terminal.jpgThese two pictures illustrate the power wiring on a the terminal of an electric dryer. The one to the left here is the old-style three-wire configuration. Most people have this type in their homes. New code changes, though, require that dryers now have a four-wire cord, shown to the right. These are just just thumbnail pictures that you can click for a larger view. But I'll bet you already figured that out, didn't you?
Besides the number of wires in each cord, there are two important things to notice. First, in the four-wire configuration, notice that the dryer's grounding strap is folded back on itself. The whole point of the four-wire cord is to separate the ground from the neutral. The green wire (the "new" extra wire in the four-wire cord) is attached to the dryer cabinet. In the three-wire configuration, the grounding strap is left intact and the neutral and ground are tied together.
tn_3prong_dryer_outlet.jpgtn_4prong_dryer_outlet.jpgIf you need to re-wire the outlet, these pictures will explain the anatomy of the three-prong (left) and four-prong (right) outlets. Once again, these pictures are just thumbnails--click 'em for a larger view.

Sure hope this helps you find a resolution to your delimma! Best wishes.

Wire 3 prong cord


Electric Dryer How To Hook Up Cord pixel_trans.gifFor Three Prong Cords
the Center cord wire goes on the center terminal,
the left on the left ,
and the right on the right.

Note: There should be a ground strap or wire that runs from the center terminal to the dryer case.

For Four Prong Cords
the White cord wire goes in the center,
the Red on the Right,
the Black on the Left.
The green cord wire goes to the case or the external ground screw.

Note: Be sure to disconnect the ground wire or strap that runs from the center terminal to the case. In this Photo (A Whirlpool Dryer) I have ran the wire that runs from the center terminal, the Light Green wire, back to itself rather than cutting it off, just incase I need to put a 3 prong cord back on it some day. The whole purpose of this 3 prong / 4 prong thing is it separates the neutral from the ground. pixel_trans.gif pixel_trans.gif3 Prong Cord Whirlpool Dryer Example terminalblock.jpg 4 Prong Cord Whirlpool Dryer Example 4prongcord_small.jpg

Switching electrical plugs


it sounds as if your plug configuration is for 220 volts. that means that all wires are needed to operate the unit. white is the common and red and black are both power leads. in other words...the red lead provides 110 volts and the black provides 110 volts, and the white is the common for both circuits. and of course the ground is for curcuit safety
to change to a three prong plug the ground must be sacrificed but with shock risk. i suggest a seperate ground wire run to an adequate ground.
a typical three prong plug will mean that the two prongs closest to the edges are the two power leads and will use the red wire on one and black wire on the other.(doesn't matter which one goes on which prong)
the white will go to the center or usually odd shaped prong. be sure and be safe!
hope this helps.......................jay
