How Can I Test My Dryer Outlet?
If your clothes dryer won't work, the unit may be broken, or there may be a problem with the dryer outlet. Try the following to determine whether the problem is with the outlet.
Testing a Dryer Outlet
Turn on your multimeter and set it to the 240 volt setting. Insert your meter lead prongs into the outlet's "hot" slots, which are the ones slanted at 45 degrees. The meter reading should be between 220 and 240 volts. Test each of these two hot leads with the neutral slot, as you tested the hot leads. This voltage should be between 110 and 120 volts. If it is not, there is a problem with your outlet.
