How to Replace a Dryer Outlet
Dryers require a special dryer outlet to function properly. This outlet is designed to provide the dryer with both a 240V and 110V electricity supply. Dryers require the 240V supply to heat up, while the 110V supply is used to provide electricity to control the timers in the dryer.
Over time outlets can become damaged or simply stop working for a number of reasons. There's no point in trying to fix these dryer outlets due to safety concerns and the fact that they're so cheap to replace.
Step 1 - Turn Off the Power
Before starting work on the electrics in your house, it is essential that you first switch the power off. If the power is left on, this task can be very dangerous. Either remove the circuit breaker for your individual circuit, or if you're not sure which circuit breaker needs to be removed, then you should switch off all the power to your house.
Step 2 - Remove the Old Receptacle
The old receptacle now needs to be removed from the wall by unscrewing the two screws which are holding the faceplate in place. Once these screws are removed, it should then be possible to pull the outlet away from the wall slightly. However, you must be careful because it will still be connected to the wires in the wall. Put the screws in a safe place so that you can use them again later.
Step 3 - Remove the Terminals
The terminals can then be unscrewed using a small electrical screwdriver. Once the terminals are unscrewed the whole outlet should then quite easily come away from the wall.
Step 4 - Replace the Outlet
The outlet now needs to be replaced with the new replacement outlet. Start by threading the cable through the cable grip and then hold the cable in place by tightening the gripping screws. Make sure that the insulated section of the cable is clamped rather than the bare metal.
Assuming you're replacing the outlet with one of the same size and type, there shouldn't be the need to make the hole any bigger. If you are fitting a different outlet, then you may first need to change the size of the hole.
Step 5 - Wire the Outlet
If you have enough wire to work with, cut off the old bare wires so that you can work with a fresh piece of wire. Use wire strippers to strip around ¾ of an inch from each of the individual wires.
The grounding wire should be connected to the green screw and the neutral white wire should be connected to the terminal. The red and black wires should be connected to the other terminals, but it doesn't matter which way around these go.
Step 6 - Replace the Electrical Receptacle
Screw the receptacle back into the electrical box by pushing all of the wires inside of the box.
