Kitchen cabinet lights come on and off randomly

I bought the Hampton Bay halogen oblong three stage dimmer lights for my kitchen. They seem come on randomly without using the dimmer switch.

    I have the same problem. I installed them last month. When I installed them I noticed that I didn't even have to touch the dimmer button to turn them on. I just had to touch the cord.

    I tried to put the excess cord out of the way, but they still go on by themselves. I will check them before I leave the kitchen to make sure they are off and that I didn't leave them on by mistake, but later that night they are on.

I have replaced Decora dimmers with the Adorne dimmers not the lighting is emmiting a high frequency noise in the mid dimming range. The lighting is 20/35 watt halogen lamps. Why and how can I fix this?


They design dimmers for either incondescent lighting or fan motor controls. Always check which one you purchased. You can't use the motor control dimmer on lighting and vice versa. Even if you purchased the correct dimmer remember that it is for incondescent lighting only (ordinary light bulb). Incondescent lights have a resistance whereas fluorescent has a capacitance and an inductance. Halogen lamps may have a capacitance and an induction too and are creating havoc with the mosfet transistor inside the dimmer. This can also cause the dimmer to fail. Read the instructions on the dimmer to see what type of lighting is allowed.

How to upgrade the under cabinet lighting in your kitchen.


Hello. Here is a great weekend project that anyone can succeed with. Under cabinet lighting is such an enhancement to the function and cheerfulness of your kitchen. My most recent experience with this was very successful. The kitchen really needed the extra light and, the home owner let me choose the fixtures. I selected Utilitech line Voltage Xenon Lights from Lowes. These units come in three lengths, 12", 18" and 24". They can operate alone or in groups, they use 110 volts and no transformers, and they have a high/lo/off dimmer switch built in. Finally, they can be installed using the enclosed plug-in cords, or direct wired, and you can link up to 600 watts. A twelve inch bar is 40 watts.

All of that said, all you need to proceed is about 45 minutes per cabinet, and the following tools: electric drill and a set of wood flat drill bits, flat head screwdriver, philips screwdriver, wire cutters, wire strippers, pliers, safety glasses and a small mirror. The mirror will assist you in tightening the screws as you install the fixtures under the cabinets. Turn off the power at the breaker for the circuit you are working on [unless of course you are going to use the plug in cords included in the box instead of direct wiring].

VERY USEFUL TIP: probably the most difficult part of this task could be mounting each of the light bars uniformly under the cabinets. Recognizing this, I made a template for each of the three lengths of fixture so that I knew exactly where to predrill and start the two mounting screws required per fixture. These templates were made from still cardboard, cut with a razor blade knife, although you could have used 1/4 inch plywood just as well.

Switch doesn't work


Because the switches have electronics in them the ground wire may be very important to give it a full 120 volts to be able to run. Also double check your lighting, these dimmers are likely for incondescent lighting only (light bulbs). A compact fluorescent or some other lighting may blow the switches. If your lights are led they may not have sufficient resistance so that the dimmer knows that you have any lighting at all. Fluorescent lighting has to high a capacitive reactance and or inductive reactance. Halogen or other lights may cause troubles too. Check the directions on your switches to see if they were for incondescent only or for fluorescent only etc. Also modern bulbs don't seem to screw far enough into the sockets because of their fat necks that bottom too soon. You may have to turn off the power then put your finger inside to bend the bottom contact up enough to touch the bulbs.

Hi! Will the Carlon Model AR170 Clamp-on dimmer switch work with my low voltage halogen table tamp? Thanks, Lee


It will probably "work," but it is NOT recommended. The device is not rated for low-voltage halogen (neither magnetically nor electronically controlled low-voltage halogen). The consequence of using a device not rated for low-voltage can include flickering, humming, or over-heating (note, even if you hook it up and it seems to be working OK, it might still end up over-heating).

Hi Jay,
Ive suspect that there's a problem in the main line of the wiring. Since four halogen bulb are already replaced with a new bulb and bypassed the dimmer switch concentrate now on the wiring and the main panel board. Look for a tripped/busted breaker on the box, reset it.Replaced if busted. If nothing works, you need to check the wiring on the ceiling for open.
Hope it may help you.
Have a nice day!
Thanks for using fixya.

I am going to stick my neck out a little with this one although I agree with BoomerP. The clue of halogen bulbs is feeding my answer. Halogen bulbs require a high voltage transformer to operate and won't normally work with a dimmer but I never tried it. Bypassing the switch should bring them on though. If you have the proper voltage at the switch and they don't work with the switch bypassed, its probably a bad transformer in the fixture. Good Luck. Be careful.

We want to install a dimmer switch for I halogen light. It is a Childs light with a row of 4 cars each with a 60w halogen bulb in. The dimmer we have brought says it is a 60-400w but must be derated to a...


The numbers don't immediately make sense to me (60-400 to 60-125?... doesn't sound right). Also, does it mention the circumstances under which you should be derating? Can you check those two pieces of information - it may help.

Most basic dimmers are rated for 600-Watts. Usually then need to be derated when installed alongside other dimmers (which as a rule of thumb, means only load up to 500-Watts if there are two dimmers, and only 400-Watts if there are three or more). Many installers also use a general rule of derating every piece of electric equipment by 20% - which is generally not required by the manufacturers of dimmers.

Regardless, there's a mismatch between the information you've given and the industry standard. Can you provide the excerpt from the instructions?

You said they are 50 watt GU10's, so I would assume they are 120V halogens, and you must simply have gotten a bad dimmer. But if these GU10's are 50 watt equivalent (LED's or CFL's) then the bulbs will have their own transformers built into them, and would be incompatible with a dimmer switch. It also might be the case that you have low voltage halogens which would use a transformer, shared or individual, and these would also be incompatible with a dimmer. (I don't know offhand if GU10's are available with low voltage halogens.)

On/off works but dimmers do not. leviton toggle


If each pendant has an individual transformer that is about the size of a hotwheel then you need a dimmer specifically for ELECTRONIC LOW VOLTAGE. A lot of electricians don't know that the different types of lights require different dimmers. Most store bought dimmers are for incandescent lights only, and some nicer dimmers like the Lutron Maestro's are rated for incandescent or MAGNETIC Low Voltage which require a different Sin wave interuption. I don't know that leviton makes a dimmer in that style for Electronic Low Voltage. You could install a Lutron DVELV300P-Wh, but that is a Decora opening. http://www.lutron.com/CMS400/WorkArea/downloadasset.aspx?id=25437
Here is a link to explain the difference in how the dimmer needs to work. Good luck!

I have a problem with my kitchen's recessed lighting. For some reason, the six bulbs will go out during the evening hours, then come back on. There is no pattern, with one, two, three or four of them out...


It sounds as if you may have higher wattage bulbs and/or the wrong type of bulb installed in the can fixtures than the recessed cans are rated for.

When the wattage of the bulbs is higher than the rating of the fixture, and/or the wrong bulbs are being used, the recessed can's thermal overload device will shut off the light, to prevent damage and a possible fire situation.

It is unlikely that you've got a faulty dimmer, since you state that not all of the lights go off at once, thus it can be narrowed down to each can and thus the thermal overload being the culprit.

I would suggest you look inside the recessed can light fixture and determine what the maximum wattage bulb you can use, (60, 75, 90 watts, etc.) and use the next lower wattage bulb instead. I also install only Halogen bulbs in recessed cans, (they have a flat lens vs. a rounded bulb lens area like PAR type bulbs). Halogen bulbs are also the most efficient incandesent bulb that provides the whitest light possible and directs more light (and thus heat) downward away from the recessed can.

I avoid using a standard light bulb or PAR type bulbs in any recessed can fixtures as they tend to heat up quite a bit and cause the thermal protection to trip frequently.

As a Master Electrician that has installed literally thousands of recessed fixtures and dimmers, I can say that my customers prefer the Halogen light over standard bulbs and they last longer too.

I hope you find this Very Helpful and best regards!
