I bought a Lutron Dimmer Switch and there is a light on in the background when I turn the switch off. It is suppose to be that way. It seems to be hotter when the switch is off instead of hotter when the switch is on?????

First off, if your dimmer is getting hot, then there is something wrong. This is dangerous. Do not leave that dimmer in the wall. Remove it.

1) A typical wall switch controls up to 1400 Watts. Look at the watt rating of your dimmer. A 600 watt dimmer will control up to 600 watts. If you have 600 watts on your dimmer, expect a shortened lifespan for that device. If you have more than 600 Watts, expect overheating and possible fire.

2) Lutron makes 1000 Watt dimmers

3) Type of bulb: Review the specs shown on link above because they show wattage, and they also show which light the dimmer is made to control

4) If your lights are on a 3-way switch, then dimmer has 3 screws and connects to 3 wires. If your wiring is incorrect, it might give symptoms shown above.
If your switch had 2 wires and you put those wires on a dimmer with 3 screws, it might be wired incorrectly.
Check wiring. Re-post a question if your are confused about details.

5) There might be a short in the circuit ... or in the dimmer ... replace dimmer with another one from Home Depot and see if symptoms persist. Disconnect ground wire as a test only and see if symptoms disappear ... if so then there is a short somewhere in the circuit
Don't burn the house down.

The LED indicators on my Lutron Maestro continuously run up and down without stopping and the lights (or fan) will not work? It seems as if the entire switch is frozen... Whats the problem?


1) If this installation was working before, the Maestro has a small pull-out circuit breaker that lets you reset the device. This is called the FASS Front Accessible Service Switch, located at bottom of dimmer where it meets cover plate.
Open sample Lutron Maestro dimmer manual to see FASS illustration
http://www.lutron.com/TechnicalDocumentLibrary/0301106A.pdf

2) If this is new installation, then double-check your wiring and check that load matches dimmer capacity: 600 watt incandescent or halogen, which apparently excludes CFLs.
Some electronic devices have shortened lifespan on circuits that are not clean. Use circuit analyzer on nearby outlet that is on same breaker to see if line has interference.

These in-wall devices stop working and need to be replaced from time to time.
There are no repair parts.
Generally dimmers don't last as long as ordinary light switch, because they are electronic instead of mechanical.

Lutron makes the widest selection of dimmers.
http://www.lutron.com/Products/StandAloneControls/Dimmers-Switches/Pages/DimmersSwitches.aspx

Use link above to identify dimmer.
For example Skylark dimmer.

Then google search for a replacement.
For example: single pole 600 watt lutron skylark dimmer
Or: 3-way 600 watt skylark dimmer
Lutron also makes 1800 watt dimmers for larger loads.

How to program control with light switch


If I understand correctly, you have the Lutron Pico wireless control
And you have the Lutron Maestro companion switch or companion dimmer
Pico will not work with ordinary wall switch or dimmer >> it has to be a companion product from Lutron
eca3dbc.jpg

I have read the PICO wireless manual, and it shows no instructions for communicating with the companion wireless switch or companion wireless dimmer
http://www.lutron.com/Products/SingleRoomControls/MaestroWireless/Pages/Overview.aspx

http://www.lutron.com/TechnicalDocumentLibrary/369-144f_Pico_Wireless_Control_SpecSub%20%286%29.pdf

I have read the 120V Companion switch manual and it shows no instructions for communicating with the PICO wireless control
http://www.lutron.com/Service-Support/Technical/InstallationInstructions/Pages/InstallationInstructions.aspx?syst=Single+Room+Controls&prodn=Maestro+Wireless%C2%AE

http://www.lutron.com/TechnicalDocumentLibrary/030865c.pdf

1-800-523-9466 for technical support
Technical support online appears at page bottom

Normally manuals give you some clue as to how the product works.
The PICO manual says it's easy to control lights (I guess it's easy for mind-readers)
There seems to be no answer or hint when working with the PICO.
I think Lutron tech support is where you go from here.

Lutron Dimmer manuals
http://www.lutron.com/Service-Support/Technical/InstallationInstructions/Pages/InstallationInstructions.aspx?syst=Dimmers+%26+Switches&prodn=Maestro%C2%AE+dimmer+%26+switch

Lutron manuals show a couple things that might be affecting you lights.
1) Wattage: If you have wrong wattage dimmer
2) Type of light bulb: Dimmers work on different types of bulbs
3) Wiring: You say you got 3 wires going to the chandelier? Why you got 3 wires? Is this a 3 way switch? Are the chandelier bulbs wired separately so you can control groups of bulbs with different switches?
Does the dimmer have 3 screws? A dark-colored screw and 2 brass screws? If so, then that sounds like a 3-way dimmer. A 3-way, is where more than one switch controls the same light.

Does the dimmer have 2 screws? Then that dimmer controls a single circuit. Your black Hot wire from breaker box connects to one screw and the black wire to Load connects to other screw.
A quick glance at Lutron wiring manual shows that Hot and Load wires connect to either screw.
The question is your 3-wires from the chandelier ... does the black Hot wire from breaker arrive in the ceiling box first? Or does it arrive in the wall box first? If your Hot arrives in ceiling box, then the Hot must come down to the switch box and connect to a screw on the dimmer >>> a second wire connects to other screw on dimmer and travels up to the ceiling box where it connects to black wire on chandelier. The white wire on chandelier connects to white Neutral.
4) Dimmer might be bad

Wired up dimmer light output is not the same as when i hook it up to a regular switch


1) Overview of product indicates it dims by electronics (they say saves 15% electricity)
The electronics might be bad
http://www.lutron.com/Products/StandAloneControls/Dimmers-Switches/MaestroDimmerSwitch/Pages/Overview.aspx

2) Load types
Different dimmers are made to work with different types of lighting
Depending on your model number, the type of load may be a factor
http://www.lutron.com/Products/StandAloneControls/Dimmers-Switches/MaestroDimmerSwitch/Pages/Models.aspx

3) Total load
A regular 15 amp light switch carries 1440 watts
If you have the 600 Watt dimmer, load wattage should not exceed 600W >>> add up total bulb wattage

4) Lutron seems to have about 60 different manuals
A quick look at the wiring seems straightforward 1-1 wiring replacement with ordinary switch
Did you connect ground wire to green screw on dimmer?

5) If the dimmer and load requirements match with the dimmer you own, I think the problem might be a short .... exactly where the short is located is solvable by testing the lights and timer and surrounding circuits with a multi-tester >>> the testing would start at the dimmer.

6) All considered, you could replace the dimmer with another one from Home Depot and see if same problem persists.

I AM REPLACING A LUTRON DIMMER SWITCH AND HAVE i THINK MADE ALL THE RIGHT CI=CONNECTIONS - COULD A FAULTY GROUNDING BE THE PROBLEM?


As a general rule, grounding will not affect operation of dimmer.
Type of dimmer, type of switch being replaced, type of load, and how you connect wires will affect dimmer.

Here is Lutron dimmer switch page
http://www.lutron.com/Products/StandAloneControls/Dimmers-Switches/Pages/DimmersSwitches.aspx

What is the load? Are you wiring dimmer to a ballast? Or fan? Or incandescent lights? Or florescent lights?
Are you replacing a 2-way or 3-way switch?
What color are your dimmer wires?
How many wires were connected to switch?
Can you re-install the switch, and know where each wire went?
Did you replace a light with a fan, and then want the dimmer to slow the fan? Not every dimmer will work with a fan, or florescent lights.
Dimmers cannot dim LED lights.

If I know what type switch you are replacing, and the type of load you want to control, and the specific dimmer you have, I can answer the question.

Dimmer switch seems to be broken as of yesterday. cant get light to turn on, by using dimmer or push switch. want to pull plate to compare. Little on/off switch at bottom won't initiate light


I haven't used this one and I couldn't see anything specific on the Lutron site about how these plates attach, but if there are no visible screws they have to just snap on and snap off. I can't believe they would have any luck selling a product that required special tools to remove the wall plate good luck, Al K
