Answer for USA, Canada and countries running a 60 Hz supply service.


Three-wire outlets are now obsolete so don't change anything on the appliance.

You should change the outlet to the correct 4-wire kind but it must be done correctly and safely. So don't attempt to do it if you don't know what you are doing.

Call in a licensed electrician to install a new circuit for you with the right sizes of circuit breakers, the right size of wiring, a GFCI if necessary and the right type of outlet to supply your new appliance which has a four prong cord.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Can you plug a three-prong dryer into a four-prong outlet or is there an adapter you should use?

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.


What is wrong if you changed a four prong to a three prong and the dryer is not heating?

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.


You are trying to change a 3 prong cord to a 4 prong your new dryer has two green cables attached to the inside of the dryer?

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.
