4 wire dryer plug - help needed

[Larry Wiseman]

Do I need to hook the green strap from the washer to the middle white wire or just leave it unhooked?  

[Repair-man]

The green strap must be placed under any nearby screw on the outer cabinet, usually the same screw that holds the terminal cover on.

Nice pic and if you will notice the red wire the white wire and the black wire are all conected to their same colors. Red to red, black to black, and white to white, with the green wire tied into the frame. Very nice.

What is the second white wire under the screw from?

[JWWebster]

That fat white one is common for the heater. The skinny one under the screw is common for the motor. Ain't seen the schematic just guessing.

[whirlpooltech]

Looks to me like the fat white one is the dryer cord.

[JWWebster]

well we now the dryer cord is the fatest but I was thinking you were commenting on the slightly smaller but still hefty wire above that one. Now you done got me curious. Ain't no tellin with these new fangled machines. You might could hook a monitor up to that sucker and get the internet on it. LOL

What is the second white wire under the screw from?

One of the white wires goes to the Door switch and serves as Neutral to the motor and/or the drum lamp. The other white wire goes directly to the electronic control on the panel.

A 240 volt heater has no neutral.

Samsung Dryer Manual

That didn't really answer my question.  The instructions told me to put the green strap wire with the white in the middle.  The dryer wouldn't power on.  Saw other sites on the internet saying to take off the green wire from the dryer and that the green strap wire from the dryer didn't even need to be hooked to anything.    We removed it and the dryer powered on.  We ended up hooking the green strap wire with the cord green wire and everything is working fine.  Don't understand why the Samsung directions would have bad directions for wiring.

Remember these are Koreans making the manuals. Some of their instructions are downright comical in the way that they explain how to check voltage, etc. Very primitive translations to say the least.

from PDF page 42 of the Samsung Manual:
"... the electric shock may occur by touching and be careful that the strong and weak electricity are mixed."

3-Wire Cord: (no green ground wire)
Neutral (white) connects to the center Terminal Strip
and a metal Strap is used to connect it to the Washer chassis.

4-Wire Cord: (with green ground wire)
Neutral (white) connects to the center Terminal Strip,
but the metal Strap is disconnected from the Washer chassis.
The Green ground wire connects to the Chassis.
