How can I tell if my dimmer switch is too low?
If you select a range that is too low for the voltage you are testing, you will see “O.L.” on the Liquid Crystal Display (LCD). Set the range selector to a higher voltage range. Attach one of the DMM’s test leads to the second black wire on the dimmer switch. Attach the second test lead to the second 110-volt test cord lead.
What should I do if my dimmer switch is burnt out?
Place the dimmer switch on a nonconducting surface, such as a dry, wooden workbench or a rubber mat, to prevent potential shock hazard. Attach one lead of the 110-volt test cord to one of the dimmer switch’s black wires. Turn the function switch on your DMM to the AC voltage position.
How to Know Your dimmer switch is compatible with your fluorescent lights?
Check that the maximum wattage of the dimmer has not been exceeded. Have an electrician check the fixture. If you’ve just replaced fluorescent lights and the new lights are also having trouble, but you’re sure the lights and dimmer are compatible, a plausible cause is the ballast in the fixture is nearing the end of its life.
How do you test a dimmer switch on a DMM?
Attach one lead of the 110-volt test cord to one of the dimmer switch’s black wires. Turn the function switch on your DMM to the AC voltage position. If your DMM is a manually ranging meter, set the range selector switch to the 150-volt range.
Is there a way to test a dimmer switch?
Unlike ordinary receptacles, a dimmer has wire leads instead of line and load terminals. If you believe that a dimmer switch may be faulty, test the device to ensure that the problem lies with the dimmer switch and not circuit connections. Replace any faulty dimmers with working ones as soon as possible.

Who was the inventor of the dimmer switch?
Dimmer switches have come a long way since 1961, when Joel Spira invented the first electronic dimmer switch. Modern dimmer switches can save energy and light bulbs, but they are damaged more easily than the auto-transformers and rheostats that had been used to dim lights before Spira’s invention. Electronic dimmer switches are solid-state devices.
