Answers to Electrical Questions About Dryer Connections
May 11, 2008
I found your site on the internet and have a question for you. Tonight when I turned on the dryer, I saw a little blue light flashing once in the back near the power cord. After the dryer stopped, my clothes smelled funny (like burn rubber smell). I opened the cover and saw the wire of the power cord that connected to the black terminal’s damaged. Enclosed are 2 pictures of what it looks like now, sorry that the quality of them are not that great. It also looks like the terminal block itself’s damaged as well (blue circle in the pics).
Must I change the power cord or can I simply wrapp electrical tape around the damaged wire? Do I need to replace the terminal block? Click on the images below to enlarge them.
You need to replace the terminal block and power cord. After looking at the pictures you sent me, it looks like the cause of the problem is the replacement screw used to connect the wires to the terminal block. I believe the screw was not the proper size or thread count and caused a loose connection creating your existing problem. I also recommend having an appliance repair person examine your dryer for any other problems this may have caused as well.
I have a frigidaire electric dryer with a 3 prong cord. I just moved from an apartment which had a 3 prong outlet. I have now moved into my 1st house & the outlet is 4 prong. I purchased a 4 prong wire from home depot & connected it 2 the dryer & it is not working. I have the red with the red, green with the green, & black with black. The ground wire is green i guessing since it the one that is connected to the inner wiring of the dryer. What do i do with the white cord thats on this 4 prong wire? What am i doing wrong b/c really need to wash clothes?
When connecting your new dryer cord, you should connect the wires color to color (black to black, white to white, etc…) on the terminal block. The first connection should be your ground wire. This is the green wire and it will connect to a green ground screw on the dryer’s frame; not the terminal block. If you disconnected a green wire that was connected to the neutral terminal (center terminal) on the terminal block, then connect this wire with the green coming from the power cord to the same green ground screw on the dryer’s frame. If there is a bonding strap connected between the neutral terminal and dryer’s frame, then you need to remove this for a 4-wire configuration. Please see my article Changing an Electric Dryer’s Power Cord from a 3-Prong Plug to a 4-Prong Plug for further clarification and pictures on the bonding strap.
The next connection should be your neutral conductor (white wire). This is typically in the center position on the terminal block. The next connection should be the black power conductor. Connect this to the same position on the terminal block that has the black wires coming from inside of your dryer connected to it. The final connection is going to be the red wire coming from your power cord. Again, connect this to the same position on the terminal block that has the red wires coming from inside of your dryer connected to it.
Unfortunately, not all dryer manufacturers use the red wire, sometimes it is a blue wire. I’ve also seen the ground wire colored green with a yellow stripe instead of solid green as well.
I have a Kenmore 90 Series Dryer.
I am switching back to the original 4 prong connector from the 3 prong but forgot the locations of the wires. I am assuming that the WHITE is the neutral and goes in the middle. The RED and BLACK go on the left and right. The GREEN goes to the location marked “External Ground Connector”. Now there is a GREEN/YELLOW STRIPE wire coming from the inside. I am guessing that goes with the WHITE wire? This would be the second ground wire?
The green with a yellow stripe wire is a ground wire and connects to the dryer’s frame with the other ground wires. Your neutral wire will only be white or gray in color.

I didn’t see a response to a similar question I asked to Matt’s 5/5 question. I have a 4-prong dryer and 3-prong outlet. Can I change the cord? I think I sent a picture awhile ago of the back of my dryer. Thanks so much!
You may change the cord or receptacle. However, if you change the receptacle, then you need to install new conductors back to the breaker box as well. It will be cheaper and quicker if you change the cord.
Please see my “How to” article How To Change a 4 Prong Electric Dryer Power Cord To a 3 Prong Electric Power Cord for step by step instructions with pictures.
didn’t see this listed, but i have a four prong dryer cord and a three prong outlet in my recently purchased 1966 built home. is it ok to change the cord or do i need to completely change the outlet.
You may change the power cord. Please see my “How to” article How To Change a 4 Prong Electric Dryer Power Cord To a 3 Prong Electric Power Cord for step by step instructions with pictures.
same thing with the green wire thats left when i change the 4 prong to a 3 prong. what do i do with the green wire
Connect the green wire to the dryer’s frame with the other green wires.
