Troubleshooting Under Cabinet Puck Lighting
Background: Katie, a Homeowner from Fairfax VA
[ad#block]Question: My husband installed your typical wired puck style under the cabinet lights 6 mos ago, and they work fine. They are controlled via dimmer/on/off button that is also under our cabinet. However, I bumped the ledge of the cabinet that is adjacent to one of the lights with a dish last night, and ALL the lights went out. I noticed the spring in the bulb(Xenon)broke in the light near the area I bumped , so replaced the bulb (tried 2 different ones), but the lights still do not come on with the dimmer. We’ve also tried unplugging/plugging back in and I checked to be sure none of the other bulbs were burned out. Nothing is working. Any clues? Or, any ideas why when one goes out they all go out? Thanks.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

    I have 1 puck light that stopped burning. However, the bulb looks fine and checks out with an ohm meter. What could be wrong?

  2. Dave Rongey says:

    Hi Al,
    It sounds like the light bulb is fine, so I would now focus on the wiring, and test the voltage to make sure it is getting to the puck light.
    I hope this helps,
