You have to go buy a new four prong chord, unscrew the base of the old chord, and switch them out.
Follow the wiring diagram on the back of the dryer, or in the manual for the dryer. If you don't have a diagram, don't guess - hire a professional.
My question is WHY did you replace a four prong dryer plug with a three prong! 220 volt Electric dryers require two hot legs, a neutral and a system ground wire. Sounds as though you shunted one of the hots or the neutral. You need to install a four prong plug of the same configuration and wire it exactly as the original.
It may be a 220 Dryer, and you will need a new outlet installed. There should be no extra wires when connecting the Power cord to the plug
Dryer plug three to fourOpen up the electrical access panel on the back of the dryer. You will see a terminal block with three wires going into it from the plug cord assembly. A red and black and white are now connected to the terminal strip. Look at the position and colours of the existing 3 prong cord and how it is connected. Make a diagram. Coloured wires on the outside terminals white in the center. From the center wire terminal you will see a jumper strap that goes to the frame of the dryer. When installing the four prong plug this jumper is removed completely. The kit should have with it a grounding lug that connects to where the removed grounding strip attached to the frame of the dryer. This is the attachment point for the fourth green ground wire from the new dryer cord assembly.
Have the outlet changed to match the configuration of the dryer plug.
I would not recommend trying to use an extension cord for a dryer. the better option is to either buy a longer cord that is properly sized to deal with the extra distance or have an electrician come out and either move the outlet or custom make you a longer cord for your dryer.
A qualified electrician should make the change to a dryer connection. The best way to cheaply make the change is to change the power cord on the dryer to the three hole standard.
Under the new electrical code rules three prong dryer cord receptacles and therefore cords are not allowed to be installed. As you are finding out, stores are not carrying them in stock any more. You should consider an upgrade for safety sakes, to a four prong plug cord and change the wall receptacle to a four prong receptacle. There are instructions on how to do this your self on Answers.

All three prong dryer cords should fit all three prong outlets. Dryer and stove plugs are different but as long as someone didn't use one in place of a dryer cord, there isn't a problem.

The second ground prong grounds the frame and shell of the dryer. You can attach it anywhere on the frame if there is not a specific terminal for it, or just ignore it. The two hot and 1 ground should let it function. Do not ignore the green wire or grounding conductor. Remove the bonding jumper from the neutral terminal (grounded conductor, white wire) that bonds the neutral to the metal frame. The screw on the metal frame of the dryer the bond strap connects to is where you want to land the green wire. Save the bond strap you might have to convert it back to three wire in the future.

You should install a four prong. The older ones were three prong and had no ground. An adaptor isn't made because it wouldn't fix the problem. You could make your own adaptor and cut the ground off with a pair of dykes, but don't.
The four blade dryer plug brings a separate ground wire from the machine to the electrical grounding system. The three blade dryer plug depended on the neutral wire of the plug to make this connection.
No, and adapters are not needed. What needs to be done in remove the old three blade dryer plug and install a new four blade cord on the dryer.Dryer plug three to fourInstructions should come with the new cord.
