Hi Leonard,

I'm a licensed electrician and will be happy to help you get this working again. I suspect an incorrectly wired or incompatible switch or a load that is not designed for dimming. To know which one(s) is the problem and to be able to provide a solution, I need a little more information.

1) What was the old switch brand and model number?
2) What is the new Leviton switch's model number?
3) What type of light bulbs are you trying to operate in the 3 fixtures?
4) What is the number of and wattage of each lamp in the fixtures?
5) How many switches operate the lights?
5a) If more than one switch is used, what is the brand and model number of the other switch(es)?

Thanks

6633-pl is single-pole and 3-way dimmer made for max 600 watt incandescent or halogen load. This dimmer does not work for CFL or inductive loads such as motor.

I have no idea what a 'locator light' is?? Do you mean the LED indicator that shows when power is connected?

Troubleshoot section of manual does not show any solution for LED malfunction.

It depends. Some dimmers are considered "smart dimmers," where the control on the other end of the 3-way has to be intelligent enough to send a signal back to the dimmer. If the Lightolier dimmer was a smart dimmer, then chances are that the 3-way control was designed to talk only to that specific dimmer. The Leviton product you replaced it with is a simple, basic dimmer - it should work in conjunction with a simple, basic 3-way switch.

If the 3-way control already IS a simple, basic 3-way switch - then I would simply re-check the wiring of the dimmer you replaced.

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

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.

You did not post enough information on symptoms to get a good answer. However, the most common problem with these dimmer packs is a failure of the sermiconductor that controls the amount of power going out to the attached light. In the D4DMX, there are 4 such, of a type class of semiconductors known as "triac", part industry part BT16A (the "A" is important, as it indicates an internally insulated mounting/heatsink tab). When this part fails, the output channel stops working, but the other 3 channels continue to work. Altho rarer, it is possible for multiple channel triacs to fail. The failure of a triac is typically due to (1) attached bulb filament failure (in a manner where a filament fragment shorts across the mounting posts), (2) channel overload (eg, plugging in a greater load (significantly greater wattage) than the D4DMX channel is rated for), (3) AC power line surge. You need to be a trained & experienced ELECTRONICS (ie, NOT electrician) to accomplish this repair safely & satisfactorily, and it involves soldering & specialized test equipment.
The D4DMX series is also known for failures of its control cable interface circuitry, both for Microplex and DMX. Microplex failures is more common, as that type of interface is more sensitive to induced noise from nearby AC wiring, radio signals, and standing wave reflections from varying lengths of control cabling. DMX uses a differential control signal interface, which makes it much more immune to induced noise, but it operates at a lower signal voltage which makes it more sensitive to accidental application of improper voltages on the control cable...which often happens when someone connects the DMX ports on the dimmer pack to a Microplex connector on another pack or the control console. One clue is to look at the single tiny LED right next to the control cable connectors; if it's lit green, then the Microplex signal is detected, if it's lit red the DMX signal is detected, if it's not lit at all (off) then no signal is detected which just may be an interface circuit failure. Such problems are a bit more challenging to troubleshoot internally, and requires a proper oscilloscope or logic analyzer.
In both of the above cases, you will see what may look normal on the LED display, but the dimmer pack will not function properly.
You should describe more symptoms of your problem, such as: Are all light output channels not working, or just 1 or 2? Which control interface are your using (Microplex or DMX)? What is your LED display saying? What are the present settings programmed into your D4DMX? Are any other working channels responding to the control console normally? What is the total length your control cables, including those between serial connected ("daisy-chained") multiple D4DMX dimmer packs? Do you have any non-D4DMX dimmers in the control chain, and are they all connected using the same type of control interface (Microplex or DMX)?

You posted under Leviton rotary dimmer.
Lutron and Leviton have many 3-way dimmer styles, and both make 3-way rotary dimmers.

I remember years ago replacing 3-way switches with dimmers and having same experience as you. One dimmer has to be ON for the other dimmer to dim.

Later I learned when you replace both 3-way switches with dimmers, you buy a control-and-companion dimmer set. One dimmer is main, and it lets you dim from both locations. The two dimmers communicate with each other electronically. Buy these dimmers at lighting store that specializes in fixtures and dimmers. Ask for most experienced salesperson.

I checked to see if rotary dimmers are made in the companion set. And neither Leviton or Lutron show 3-way companion set rotary dimmers.

1) Leviton spec sheet on rotary 3-way dimmers does not show companion dimmer. This indicates that Leviton rotary dimmers don't have capability of communicating with each other.

2) Lutron has image of 3-way rotary dimmers.
Image shows single rotary dimmer in 3-way & 4-way circuit.
This tells me that Lutron does not have companion dimmer for 3-way rotary dimmer.

The electronic part (a triac) that does the actual dimming in the bad channels is shorted, so the lamp always comes on at full brightness. Unless it's a special part or the manufacturer has removed the device markings, it's possible to identify the bad parts and replace them. Electronic components are available from a number of online sources (MCM, Encompass and others), or maybe even locally. Most musician supply stores have service departments or can refer you to someone if you don't want to try repairing this yourself, or you can see what service options are listed in your manual or on the manufacturer's website.

If you want to spend more than they are worth. For a real solution buy dimmers from a quality brand such as ETC Electrol or leprechaun
