I have a Frigidaire Crown Series dryer, not sure what model number. I want to convert the plug from 3 prong plug to a 4 prong plug. The existing 3 prong plug is all grey, not color coded. How do I know how to hook up the new plug??

where the green ground was attached to the body it will now be attached to the middle prong? u can use youtube to see how to go from 3 prong to 4 prong if this is confusing

It's either you convert the 3-prong outlet to 4-prong or the 4-prong cord to 3-prong. But the latter is easier and more feasible. Unplug the dryer then disconnect the 4-prong cord from the dryer. Note that it has red, black, white, and green/yellow wires but sometimes the red and black wires are both replaced by same color wire, usually gray. The red and black wires are lines L1 and L2 reversibly, meaning they can switch places, while the white and green/yellow wires are the neutral line and ground, respectively.

Get yourself a 3-prong cord and note that it has red , black, and white wires but sometimes, like the 4-pronged one, the red and black wires are both replaced by same color wire, usually gray and can also switch places. All you have to do now is connect these 3 wires in the same manner they are connected as 4-prong cord to the terminal block. The wire strapped to the dryer cabinet and connected to the green/yellow wire of the 4-prong cord wire is now left hanging. The last step is to connect this hanging strap wire to the same terminal on the terminal block (center) where the white wire (neutral) is connected and it's done.

It can be observed that converting a 4-prong cord to 3-prong cord is merely joining the neutral line (white) and the ground (green/yellow) thereby reducing the number of prongs from 4 to 3. On the other hand, converting a 3-prong cord to 4-prong cord is merely splitting the neutral line and the ground thereby increasing the number of prongs from 3 to 4.

Electric Dryer Prong Conversion

Hi,
Here is a tip that will help you with changing your dryer plug. Dryer Cord and Wiring Dryer 3 Wire or 4 Wire

The Model number could be on the top of the machine or around the dryer door or by the washer lid. if your looking for a 220/240 volt 3 prong cord you should be able to get one at lows or home depot

According to the National Electrical Code, as of 2000 all newer homes are required to have a 4-prong receptacle for all 220VAC appliances. However, if your home already had a pre-existing 3 prong outlet, you shouldn't have to upgrade to a 4 prong. The following link explains:

The main difference is how the neutral (WHITE) and green (GROUND) wires are termnated. In a 4 wire configuration, the neutral and ground are independent of each other. In a 3 wire configuration these two wires are terminated together. The instructions to convert a 4-prong appliance to a 3-prong are at the bottom of the page in the link I provided.

NOTE: If this is a new dryer, keep in mind, some REQUIRE a 4-prong plug even if you have a pre-existing 3 prong outlet. Read through your installation instructions that came with the appliance if in doubt. If this is the case, you will need to have a 4 wire outlet installed by a certified electrician.

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

IF you find that you have only a 3 wire feed for this dryer (and the reason for the 3 prong receptacle)...then you can not properly install a 4 prong dryer cord to it. You now have 2 choices....either rewire (assuming that it is a 3 wire supply) the entire run from the dryer breaker to the outlet location with 4 wire (typically a run of 8/3 with ground having a black, red, white and bare ground)and install a 4 prong dryer receptacle to match the configuration of the new dryers cord.....OR - you can remove the 4 wire cord and replace it with a 3 wire cord....re-using the ground strap - IF it is still in place.

I think you need to read the following link to make sure you aren't violating any electrical codes, first:

Yes, a 3-prong DOES have a NEUTRAL wire. That would be the WHITE terminal. A 3-prong does not have a separate ground. The NEUTRAL is usually grounded at the appliance casing by a jumper wire.

Read in the "Additional Notes" section on how to convert from a 4-prong to 3-prong. Also note that some of the newer appliances require a 4-prong plug in order to run correctly. I have a Kenmore HE3 model dryer that is currently using a 3-prong power cord. Since this model Kenmore is manufactured by Whirlpool, and is identical to the Duet, you should be okay with a 3-prong plug.
