Dryer is not heating up

On a three-prong cord there is a black, a red, and a white wire. The black and red are hot and the white is neutral (return). Return on the dryer is also in these cases the ground which is shunted to the netal case of the dryer. On a four prong, you have black, red, white, and green wires. The black, red, and white are the same as before, but the green is a direct connection to the dryer case for ground. This ensures proper grounding and was first introduced in to mobile home installations, where the electrical system may not always be properly grounded.

The difference between the 4 wire plug and the power source wire is that the plug has and additional seperate ground wire. Basically ttwo legs, a neutral and a ground. Your power source wire only has the two legs and the neutral (the white) which used to act as a ground. Notice that the white (neutral) is hooked up to the ground bar along with the grounds in the panel box. The "correct" thing to do is replace the wire from the panel box with the correct size/amperage wire.

You are going to have to abandon one of the wires and probably change your outlet to match your cord. I would abandon the red wire. You will have to do this in the breaker panel itself. If you are not familiar or comfortable working in this panel then don`t. If you are then only connect the white and black wires to the breaker that feeds your outlet and your green will be your ground which should already be connected to the ground bar. It is possible that the black and red wires are already connected to the breaker and the white to the neutral bar (this is the way it should have been wired for four wires). If this is the case just remove the white wire and tape it off and don`t use it in your new outlet.

Connect the red, black, and white wires of the new cord to where the red, black, and white wires of the original dryer wires are connected to but disconnect the ground wire (green/yellow wire attached to the cabinet) from where the white wire is connected to and connect it instead to the fourth green/yellow wire of the new cord.

This sounds like you should call an electrician, or someone that knows wiring. Red and Black are both hot, White is neutral, and Green is ground. Remove the ground strap from the center of the terminal block to the case. Put green wire to the case, white in the middle, and red or black to either side. Your last question I do not understand. But it sounds like you need an electrician to connect a 4 prong receptacle, with the proper 4 conductor wire to your breaker box.

Two options,

1) get a three wire outlet ("plug in")
2) get a 4 conductor cable.

The 4th wire is green or bare - ground the wire to the cabinet.

You are 'safer' with the 4 conductor wire. (In the past, White served as the neutral conductor and the case may have been 'bonded' to the white, providing a "ground". Today, I believe the code requires a separate ground. Even though the white and green join in the service panel and go both to ground and "back" to the utility, there is the possibility some installations are wired through a sub panel. Common use of white as neutral and ground is not allowed in a sub-panel in most jurisdictions). Black to black, Red to red, White to white and Green (or bare) to the frame. You can make a hole and connect it or use an existing screw that is nearby to make the connection.

If you have a volt meter, you can check your existing outlet. You should get 220 V between the two legs, 110 V between "red" and "white", 110 V between "black" and "white", 110 V between "red" and "ground", 110 V between "black" and "ground", and no reading between "white" and "ground".

The terminals on your existing outlet should be clearly marked and the color code of the wire should be clear although it is POSSIBLE the color of the conductors is all black. The above series of tests will help you determine what is what if necessary.

If you are still unsure, you should get the advice of a licensed electrician in your area (which I am neither)

I hope this helps you

The old three prong, the vertical prong is neutral (white wire), the two slanted are 220 volts. The new plug, the extra prong is ground (bare wire). Shut off the outlet at the breaker panel, and remove the outlet to examine the wiring to it. It should be as above--the 220 volt wires are red and black or black and black. The ground wire is bare or green insulated. Inside the dryer case, tie the green and white wires to the dryer case, and tie the two outside wires where they went with the old cord. Check with an electrician if you are unsure about this.

have you check outlet with a voltmeter or even checked breaker? Is your new rect' a 3 or 4 prong outlet? If you hooked up red's to black and black to reds it still should have worked. The 220 volt heating element is between the red's and blacks the 110 circuits would be between a red or black to white wire.

to put it kindly depending on way you connected wires unit could be damaged,replace pigtail with three wire and outlet to original.outlet wires should be black,red and white. turn breaker off attach white to middle and red,black to sides,"either side is fine".Attach dryer pigtail in same manner with white on white and if plug in and turn breaker on.If there is no operation at this point dryer possibly damaged from previous wiring.Just remember be safe when working with electrical and ask before trying to change things that aren't the same.

white always goes in the middle!!!!!!!!!!!!!!,green on top on green screw,black on one side and red on a four wire outlet,on a three white in the middle!!!!! black on one side and red on the other-mike
