20 Most Recent Leviton Decora Light Dimmer Switch Questions & Answers

You cannot use standard electronic dimmer switches with CFL bulbs, only incandesant bulbs! That is why you are getting the flickering.

With CFL's bulbs installed in a light fixture that has a non-flouresant rated dimmer switch on that circuit, you will cause the standard dimmer to fail.

You have to look at the dimmer package (sometimes printed on the back of the dimmer itself too) to see if it can be used with CFL bulbs,as many are not rated for use with anything other than standard incandesant bulbs.

Hope you found this very helpful and best regards!

Yes you short circuited the dimmer switch, it requires replacement to dim the light.

Check to make sure the hot conductor is feeding BOTH switches together, and
the switchlegs going to the individual loads

Bad dimmer. Probably not using a high enough watt rated switch. Add up the total of all bulbs to be dimmed and get appropriately rated dimmer. 8x60 watt bulbs=480 watts. Make sure dimmer is rated high enough.

Are these remote controlled dimmers? Do you have failing batteries in one of the remotes? Or perhaps a new remote control device has been introduced in or near your house that interferes with the dimmer remote signal. I had a similar problem that occurred when my boys played with their remote controlled cars.

Wiring is not best suspect.
If all the Leviton devices were installed same time, they may be failing at same time due to lifespan.
For example, ordinary on-off switch is a mechanical device with mechanical parts, and mechanical switches last many years longer than wiring devices that have electronic parts.
Electronic devices usually have standard 1 year limited warranty.

Had this problem my self a while back, here's what I found out. Firstly, it may simply be the switch is faulty. If this was a new install, take it back and try another. But before that, get all relevant information about the lights you are dimming. Here's why: Some light fixtures are incompatible with dimmers. They may dim - but not properly. Some lights/fixtures require specific dimmers to be used: incandescent or not, total wattage in fixture, and so on. Having this information may save you a trip if it's actually not the switch. Good luck.

Yes, this is a problem for some models. Continuous, uninterrupted operation can create a situation where the dimmer's "triac" (or in layman's terms - power regulator) continuously fires and a resistance will develop. This will overheat and damage the "transformer". There are dimmers with low voltage and load protection capabilities available. Your local "big box" store should be able to help you there.
