DO NOT install the Green (GROUND) and White (Neutral) wires together in a 4-wire configuration! The following link explains how to properly convert a 3-prong cord to a 4-prong cord to accomodate your new home:

http://www.fixya.com/support/r793520-3_prong_4_prong_power_cord_conversion

Newer homes now REQUIRE a 4-prong configuration to be within the National Electrical Code standards. The main difference between the 3 and 4 wire configurations is how the ground and neutral are installed. In a 4-wire configuration ground and neutral are INDEPENDENT of each other.

If you have questions about this repair, please ask me. I hope this clarifies it for 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.

Just moved, the dryer has a 4 prong plug and house has 3. Should it replace plug to dryer to 3 prong or house plug?


Buy a 3 wire cord and install it on the dryer. Hang onto the 4 wire one in case you move again.

We just moved and this house has a 4 prong dryer plug and our last house had a 3 prong dryer plug. We bought a new plug and hooked it up as it says and still nothing. Any help would be much appreciated!


You may have inadvertently incorrectly wired the dryer power cord. The following link epxlains the differences between the 3-wire and 4-wire configurations:

http://www.fixya.com/support/r3575913-installing_a_220_vac_appliance_cord

Make sure you have the wires connected properly at the terminal block. Pay particular attention to the difference in how the ground and neutral wires are connected. If you have any questions, please post back and let me know. I hope this helps you.

Swich 4 cord to 3 cord plug in


To switch from a 4 prong to a 3 prong. First remove 4 prong cord, save screws you will need them. Look a 3 prong, it will be flat with 3 wires next to each other with metal fittings on the ends. The 2 outside which are hot wires go to the outside screws on the block, and the center which is neutral goes in the center. The only difference in the cords is the 4 prong has a ground, in new construction this is code. You don't need a ground if house is wired for a 3 prong.

New house has three prong recpticle dryer cord has four prongs. Can I use a three prong cord and strap a wire to the fourth wire on back of dryer? If not got a solution?


If the new house has an existing three-wire outlet, the simplest solution is to install a 3-prong power cord on your dryer. The following link explains the differences between a 3-wire and 4-wire configuraiton:

http://www.fixya.com/support/r3575913-installing_a_220_vac_appliance_cord

So...if you need to install a 3 prong power cord, it should be wired as follows:

RED (HOT) 120VAC to RED
BLACK (HOT) 120VAC to BLACK
WHITE (NEUTRAL) 0 VAC to WHITE - a Ground wire needs to be connected to the Neutral lead at the terminal block and grounded to the dryer cabinet.

The other alternative would require you to install a 4-wire receptacle so you could still use your current power cord. A certified electrician is recommended for this job and may cost you some money. A replacement power cord, on the other hand, usually costs less than $20 and can be found ay any hardware store.

If you have any questions, please post back and let me know. I hope you find this information helpful.

I moved into a house that has the 4 prong dryer receptacle and I bought the new 4 prong plug to hook up to my dryer but there are only 3 wires on my old one. The new one has a red, green, white and a black...


be careful the voltage may be different thats why they make them with different plug configurations. check your dryer voltage requirement. usually the four wire type are for 250vac electric dryers.

Can you tell me how to hookup the three wires of 3 prong cord to the back of dryer that came with 4 wires(4 prong)? Which one goes where? I only have 3 prong plugs at my house. Thank you.


The following link explains how to connect a power cord to your appliance:

http://www.fixya.com/support/r793520-3_prong_4_prong_power_cord_conversion

Now keep in mind, some newer appliances REQUIRE a 4-prong plug in order to work properly. You may consider having a four-prong outlet installed to accomodate your dryer.

You can try these steps by referring to to section that discusses converting from a 4-prong to a 3-prong power cord.

If you have questions, please let me know. I hope this helps you.
