20 Most Recent Lutron Maestro 600-Watt Multi-location Dimmer Terracotta #MSC-600M-TC Questions & Answers

The dimmer is worn out

Wall switches and dimmers don't come apart for repairs >> nobody sells parts >> and the wiring didn't suddenly go bad.

Because the switches are relatively inexpensive, there aren't kits to repair them when they fail mechanically. Your best bet is to get an exact replacement from a Home Depot or such, turn off the breaker switch, and rewire it exactly as it was, using wire nuts and tape.

This dimmer was not made to dim a load smaller than 40VA. That halogen bulb would only have been 20VA or so.

I think that when your bulb burnt out, the dimmer over-volted the transformer and smoked it. That said, I think you have a fixture problem and, possibly, a switch problem, too.

You're in a difficult position for which I see few options --- none of them ideal. Short of replacing all your switches and wall plates in a matching color of your choice, a cheaper option might be to find a satin spray paint in or near-enough to your color and gently spraying the new dimmer(s) to match. Alternatively, Eaton makes LED dimmers in "Desert Sand" (but whether their Desert Sand looks anything like Lutron's is beyond me).

Which one? My eyes are poor and I cannot see that far.

That is normal. I assume the two white wires are connected together in the box.

This is a no-no unless they are specifically designed to do this.

The directions tell you where to connect it. My eyes are poor and I cannot see what you have!

It sounds like you blew the triac (the electronic switch) in the light. You will need to get a replacement module or a new light. Sometimes lightning will cause this. If it was a tungsten lamp they can have a large current surge when it fails.

Is original a 3-way dimmer (2 or more switches control same light fixture)?

The only device rated for a motor load is the RRD-8ANS and itequires a neutral connect.

To clarify you have a gang of 3 fans you want to control from more than 2 locations (3 or more existing wall switch boxes)?

Halogen work with AC or DC voltage ... 12 volt LED bulbs are DC. Check that transformer delivers DC, or buy 100 watt IP67 LED driver. Keep in mind the lutron DV-600 is rated for incandescent and halogen loads, and may not function as expected when connected to inductive load like transformer or driver.

I take it you don't want to just remove the upstairs 3 way switch and wirenut the 3 wires together and put a blank cover plate over the box<?>. Need to know more info. Does the upstairs box have 3 wires only? If no, then likely you will not be able to abandon the upstairs switch box as it will need to remain as an active junction box. If yes, then it becomes a rather lengthy procedure (textual). I'll sketch it out but need an answer the number of wires in upstairs box. Comment below so I may assist further.

There are a lot of DIVA models and you did not post the model number. There are multple configurations and wiring methods.

Lights require a minimum voltage. Reset minimum to a brighter level.

You might look to see if the outlet is GFI protected. It is possible the GFI (Ground Fault Interrupter) tripped and needs to be reset. If so, push the red button (reset button) firmly until it stays down (pushed in). If it does not stay closed, replace it. Also check your light bulb fed by "the switch that does not work", to make sure it did not burn out. Your switch could be good, but the bulb bad. If your light switch is not on a GFI circuit and both Lutron switches are fed by one breaker, get a volt-ohm meter, set it to the volts in a voltage range to read house hold voltage (around 121 volts), and check to see that both switches are receiving 121 volts. Usually you measure with the black probe touching a white (neutral) wire, while the black wire is usually the wire that is in series with the lamp. A black wire may come into the switch and leave as a black wire going to the bulb. If you do not have full voltage reaching your switch, you may have a wiring problem where a wire is no longer making good contact. If you are not sure about how to test with a volt meter, search on your tube for further explanations on how to test to see if a light switch is good.

Not sure if you can just splice the extra wires together. The ballast information is what matters converting to just on-off, not the finger switchswitch

yes it does,
