If your dryer gets no power, it may be time to replace the outlet. Dryers run on a 240v or 220v, which is double the voltage of standard appliances. A separate 110v supply is used to control the timer.
A damaged outlet increases the risk of fires and electrical shock, so replace them as soon as possible. You don't need advanced skills to change an outlet, but some basic wiring knowledge is helpful. Here are tips to replace a faulty dryer outlet.
Prepare to Work
For this project, you need:
- work gloves
- wire strippers
- wire nuts
- dryer outlet kit
Check with your local building codes department before making any electrical repairs. The building codes department will clarify requirements and inform you of any permits you need.
Shut off the power to the room at the service panel. If you don't know which breaker controls the room, turn off the main power supply. The main power supply is a double breaker at the top of the panel.
Wait several minutes and test for current at the old outlet with the voltmeter. Insert a probe into the straight slots of the outlet, then insert the probes in the round or L-shaped slot. The reading should be zero. If you get another reading, don't continue. Contact an electrician.
Remove the Old Outlet
Store hardware in a small container. Detach the screws on the outlet cover plate with the screwdriver. Detach the screws that hold the wires on the outlet prongs. Pull the outlet from the wall. Separate wiring, so it will be easy to install to the new outlet.
Install the New Outlet
Insert the wiring in the wall through the holes of the new outlet. The wire terminals are commonly marked. You may want to strip about one-half inch of insulation from the red, black, and white wires for a fresh connection.
If there are no markings, attach the red and black wires (hot wires) to the brass screws on the straight slots. Attach the white wire to the silver screw on the L-shaped or round slot in the middle. Connect the ground wire to the green or copper screw.
Add wire nuts for a secure connection. Set the outlet in the wall by following manufacturer's directions. Install the cover plate.
Restore power, and test the outlet with a voltmeter. You should get a 240v minus 12v reading from the two straight slots, and 120v minus 12v from other openings. If you don't trust your skill or the outlet still malfunctions, contact an electrician, such as those found at RDS Electric.
