Hooking up a 4 prong plug to dryer

SOURCE: REPLACING DRYER 4 PRONG PLUG

This is common issue. Due to some building codes the 3-prong configuration is no longer used in homes. The wiring is similiar with one exception. The 4-wire plug uses an additonal (WHITE) NEUTRAL wire.

Here's a brief explanation of how the plugs are configured:

Dryer 3 prong wire configuration:

RED - 120 VAC
GREEN - GROUND
BLACK - 120 VAC

Dryer 4 prong wire configuration:

RED - 120 VAC
GREEN - GROUND
BLACK - 120 VAC
WHITE - NEUTRAL

BOTH plugs provide the SAME source voltages to your appliance:

220 VAC - provided across the RED and BLACK leads are what drives your heating circuitry.
120 VAC - usually tapped of the BLACK wire is used to run the drive motor and timer on MOST dryers.

The wire terminal block in the back of the dryer should have a black, white, and red wire running to it from the dryer wiring harness. With the 4 prong plug, simply attach the BLACK, WHITE and RED wires at the terminal block ensuring that you match the RED and BLACK wires as they are configured and attach the WHITE wire at the remaining terminal lug. Make sure you screw them all down securely. Attach the remaining GREEN wire to chassis (dryer frame) ground. I hope ths helps you.

SOURCE: I have to change the

• green = ground (attach directly to the case, should be a green painted screw near the opening
  
• red = hot 110v connect to the red on the dryer
• black = hot 110v connect to the black on the dryer
• white = neutral connects to the blue (only if the blue is in the middle)
• neutral is always in the middle with a hot wire on either side of it.
• also make sure all the connections are tight

*First ; before starting unplug unit or shut off breaker.

you should be able to match up color for color on your dryer, the fourth wire, green (ground) screws to the chassis, or cabinet. if your wires aren't coded as you say, it is red, white and black, left to right. see picture I've supplied.
hope that helps

good luck
