The most likely possibility is that the dimmer simply broke. I would call Lutron tech support at 1-800-523-9466 to help you diagnose it and possibly send you a replacement (available 24/7).

SOURCE: 3 way dimmer switch ace 6443v-k only dims in one direction.

At the switch you have a common ( either a hot or a wire going to lt). And two Travelers( Wires going from one switch to the other) Make sure your not mixing one of the travelers up with the Common easy mistake happens all the time. Travelers are always in the the same at the other end of the 3w switch , you may need to take it apart and look. If you need further help send me more details I hope this helped

SOURCE: need to replace the HPM dimmer switch with a normal switch

This is not a difficult job. First of all go out to a home depot or other hardware store and purchase one three way switch. They come in white, cream, and brown.

Back home, kill the power to the lights you are working on. Then open up the dimmer switch, the other switch doesnt need to be changed. Now, simply draw a diagram of where each wire color is now connected and remove the old dimmer. Reconnect the wires. Remember that the white wire goes on the dull color screw and the other two go on the brass screws. Turn the power back on.

If you do all this and the switch only works correctly part of the time just reverse the two wires on the bright brass screws. Please mark this answer as a fixya!

SOURCE: Dimmer doesn't turn off!

There is one more thing that you can try, turn the power off from the breaker and wait about 20 seconds, then turn back on. If that doesn't fix it you are probably right about the dimmer being bum. It is very rare that Lutron devices are defective. You can contact them directly and see if you can get it replaced since you no longer have the receipt. You may have to send it to them before they will send you a replacement but it beats spending another $50

SOURCE: Lights won't dim

Here's a link to an article that explains the wiring. If you've followed the guidelines, then maybe you have a faulty dimmer.

Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps.
• Power window switches
• HVAC control head assembly
• Radio
• The instrument panel cluster (IPC)
When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) display (radio) turns on at maximum brightness. When the park lamps are ON all incandescent back lighting turn ON at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). The BCM then supplies voltage to the instrument panel dimmer switch through the instrument panel dimming lamps control circuit. The setting of the instrument panel dimmer switch determines the amount of voltage that the instrument panel dimmer switch supplies to the BCM through the instrument panel dimming lamps low reference circuit. The BCM then sends a pulse width modulated (PWM) voltage to all the interior lamps. All the vacuum florescent (VF) and incandescent back lighting lamps are provided a specific voltage and are then grounded. When the headlight switch is turned to the PARK or HEADLAMP position, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.

I would have it checked for DTC'S - diagnostic trouble codes stored in the BCM !
DTC B2624 Display Dimming Input Range/Performance
The body control module (BCM) supplies voltage to the instrument panel dimmer switch through the instrument panel dimmer switch signal circuit. The dimmer switch varies the voltage and returns the new voltage to the BCM through the dimmer switch signal return circuit. The BCM uses this voltage to determine the illumination level of the instrument panel lamps.

DTC B2625 Display Dimming Pulse Width Modulation (PWM) Output Circuit Range/Performance
The body control module (BCM) receives a variable voltage from the instrument panel (I/P) lamp dimmer switch. The BCM uses this signal in order to vary the illumination level of the I/P lamps. The I/P dimming lamps output from the BCM is a pulse width modulated voltage supply used to light the I/P lamps. If a malfunction occurs in the I/P dimming lamps output circuit, this DTC is set.

DTC B2662 Park Lamp Switch Circuit Malfunction
The park lamps are controlled by the turn/headlamp switch. Positive battery voltage is supplied to the switch through the EXT LP fuse. When the turn/headlamp switch is placed in the park or head position, battery voltage is supplied to the park lamps. The body control module (BCM) is also connected to the park lamp circuit to sense whether or not the park lamps turn ON when the low beam or high beam headlamps are turned ON. The BCM also uses the parklamp battery positive voltage to power the instrument panel (I/P) dimmer output circuit. If the BCM senses that the low beam or high beam headlamps are ON and the park lamp input is not active, DTC B2662 sets.
Do the park lamps work ?

Dashboard lights will go out randomly. It has done it for short periods before but it did it for 200 miles on hwy in dark.


The sensor is usually located on the top of your dashboard. You might see it if you look into your vehicle through your windshield at your dash.
I have seen( one time ) that a gps was bright enough that it caused the dash lights not to come on because the sensor thought it was light outside.
Or you could have gotten a bad sensor.

Which fuse is for the instrument panel back lighting?


Does the radio play ? Are any other back lighting components not lighting ? Does the HVAC control panel light up ? You probably need new radio !
The second interior lighting group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination, LED illumination and incandescent lamps.
When the ignition switch is turned to the RUN position, the radio VF display turns ON at maximum brightness. When the park lamps are ON, all incandescent and LED back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. At the same time all VF displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the body control module (BCM). When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all VF displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.

Humming and failure to dim


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.

I changed the light bulbs in the fixture it controls, now it does not work. What is wrong?


This switch is designed to dim incandescent lamps. It has nothing in its description about being used with CFL (compact fluorescent lamps) types. If you are attempting to dim standard CFL types, it will not work.

CFL's are available in both dim-able and standard types. As you may have guessed, only those marked as "dim-able" will work with a dimmer switch. Dim-able CFLs cost slightly more than standard CFLs but may be controlled by any switch. Dimmer switches may only control incandescent and other type lamps that specifically state they are compatible with dimmer switches.

If you are attempting to dim incandescent lamps, make sure that you are not trying to dim lamps with a total wattage greater than the dimmer can handle. Most dimmer switches are rated for 600 watts, if you have two dimmer switches under one wall plate, the wattage rating drops to about 500 watts. This de-rating is because of the heat the switches create. There are dimmer switches that can dim more than 600 watts, but the price skyrockets for a 1000 watt dimmer, and keeps climbing.

If your wattage is within the limits of the dimmer, check the bulbs. If they are ok, the dimmer may have failed and require replacement.

If you found my reply helpful, please rate it "4 thumbs up". Good luck & thanks!

3 way dimmer turns on and off, but does not dim


All your wiring looks good. Many times dimmer just have problems and are faulty. You should note that the dimmer can only handle 600 watts. If you have that or more on it, than you have probably fried the dimming mechanism. In either case the dimming mechanism is not working properly and you will have to take it back and get the same dimmer or a different one. Tell the store they sold you a faulty dimmer and you can get a replacement at no cost.

I just wired 2 3way switches with 3 lights in between them. Tried 2 different dimmer switches on the circuit but neither would dim the lights nor operate the lights as they should. The lights perform...


In general practice, you can only install ONE 3-way dimmer switch to control the lights. If you use two regular 3-way dimmer switches, the circuit won't work.

However, newer technology allows for double 3-way dimming from different locations. See this article about how to do this:

What sort of light is it , dimmer switches normally only work on Incandescent type lights not flourescent type.

Otherwise it sounds as if the dimmer function is faulty.
