Cool connecting 4 prong cord to old kenmore dryer. Electrician advice needed plz!

Hi,

I have a kenmore dryer and am trying to figure out from someone who has upgraded a 3 prong to a 4 prong cord what in the world I should do with the green/yellow wire that is built into the dryer.

Some guys ive talked with yell at me Not to hook it to the neutral / white post in the middle and to just cap the old green/yellow wire instead

One tech emailed me the PDF of what looks to be my dryer and it looks to me to say that im supposed to put the green/yellow on top of the white wire from the cord.

Is that correct?

The cord ground must go to frame. The frame grnd jumper must be removed from the neutral terminal. I'm not sure from the picture if the strap I pointed to goes to the neutral terminal but if it does it needs to be removed from the neutral terminal.

Hello Ray,

thanks for the response. I had it originally like that but another DIYer sent me the manual for my dryer and its showing that its supposed to be connected to the white neutral terminal.

Why would they have it like that in the manual?

Any ideas?

Im just super scared this will be the death of me when I go to plug in this old monstrosity. Lol. I dont want to get zapped.

You're right....

On page 18 of the installation manual they show the wire jumper between ground and neutral. The diagram is absolutely incorrect for a four wire installation. You do not connect ground and neutral together in a four wire supply circuit.

Ray's illustration is correct by code.

As I said if the strap does go to the neutral terminal you remove it. In Aalternate Instructions it does say to remove the yellow green but the meaning of
STEP 3. Remove the neutral grounding
wire (green/yellow wire) from external
grounding connector screw. Loosen or
remove terminal block screws. Connect
neutral grounding wire and the neutral
wire (white or center) of power supply
cord or direct wire cable under the center
screw of the terminal block.
Is wrong. Not sure what they meant to write. Ground and neutral are never connected in a four wire system.

I took off the wire block to see if that metal piece connects to anything. That metal strip goes underneath the 3 wires and doesnt connect to any of them. It runs behind the connector block.

So you are saying that the manual is INCORRECT for a 4 wire setup??? I should still put both greens to the greenish screw on the case of the dryer?

How is it best to set this up so it passes code? I dont want to get a shock!

That bonding strap was never connected to the neutral post.
Both greens should only connect to the frame.
Follow Ray's diagram above.

Ray - I think that strap you are pointing to is just a mounting bracket since it looks painted grey and not centered on the neutral. The other end of the frame ground jumper (yellow/green) may actually be wired to the neutral - then the installation directions make sense. Way to find out is to either find the other end of the wire or meter it out.

minmatt - Whether the green/yellow is wired right or wrong everything will still work. One way is a bit safer than the other.

That looks like a grounding strap. You can see the notch where it would fit under the terminal.
