1. 1

   Please read all steps, tips and warnings completely before attempting.

2. 2

   Identify the reason that a lamp (lighting fixture) won't function. The most common are:

   • Seedling burned out.
   • Bulb socket oxidized, burned, corroded, or otherwise cleaved so as to prevent proper electrical connection with the bulb contacts.
   • Transformer has overheated and a winding has "shorted" out or "opened" up.
   • The control (on / off or dimmer switch) if present, has failed.
   • The cord cap (plug), string ready (that which brings voltage from the wall receptacle to the fixture), or wiring between the control and the transformer or transformer to lamp socket has open, or shorted. Look for wire and insulation that is discolored, burned off, broken, etc.

3. iii

   Determine value of the fixture or price of replacement. The time and / or cost of the repairs may not warrant repair. Warnings beneath should besides be reviewed before attempting.

4. 4

   Employ extreme care to prevent burns. Allow plenty of time for a lamp to cool earlier troubleshooting. The lamps, while hot, tin can cause pregnant burns. The lamp operating temperature tin exist about 1,000 °F (538 °C).

5. 5

   Exam the bulb(s) in known a working lamp to determine if they are "practiced". Never handle the glass of the lamp with blank hands. Utilise a textile or wear gloves when treatment the bulb to avoid contact with pare. The oils from the skin that would exist left on the lamp will result in early lamp failure. If unable to test by swapping, assume the lamp is expert.

6. vi

   Unplug (or otherwise disconnect) the fixture from the power source. Shutting it off with a wall switch is Not considered "asunder".

7. 7

   Remove the lamp (if not already out) from the socket or holder. Examine the socket or holder electric contacts. If they appear burned, discolored, oxidized, etc., gently scrape the contacts slightly until shiny metal becomes visible.

8. 8

   Install the lamp. Inspect the socket or holder contacts where they touch the lamp. If they appear loose, you tin can endeavour to tighten them by squeezing them together (gently) with needle nose pliers (afterwards removing the lamp). Bank check that any area of the contact previously cleaned of discoloration, etc., is aligned with the points of contact to the lamp.

9. 9

   Test the recent adjustments / cleaning. With a proficient bulb in the fixture, plug it in to power to see if functions.

10. 10

    Remove the base of the fixture or other area to access the wiring compartment or switch. Unplug (or otherwise disconnect) the fixture from the ability source. Shutting it off with a wall switch is NOT considered "disconnected". Accessing the wiring compartment depends on the fixture. Some require a plate, screws, or other protective barrier to be removed. Sometimes it may exist a simple piece of cardboard glued to the bottom of the fixture base of operations. Try to remove information technology causing a minimal amount of damage, as it volition be needed to exist reinstalled when done. Under the base embrace (cardboard) yous will find one or more of the following: transformer, power string and the command switch (unless you are working with a pole lamp Torchiere blazon where the on/off/dimmer switch is in the pole).

11. 11

    Audit for burned, broken, or loose wires. Splice, solder or wire-nut together to make repairs. Test every bit outlined previously above.

12. 12

    Apply a Multimeter or VOM (Volt-Ohm Meter) for boosted testing if the fixture however does not function. At this bespeak if you haven't found the problem, additional tests Use-a-Multimeter will be needed. If this term (multimeter) is non familiar to you, and y'all don't have a clue as to how to mensurate voltage and continuity, it may be best to turn the work over to a repair store (if the fixture is important to y'all).

13. 13

    If you tin can use a VOM and have one, so (with the fixture plugged in) measure out the transformer output usually 12volts, if nothing there, then measure the transformer input 120 volts, if you take the 120 volts, then the transformer is bad near likely.

14. 14

    You must have the on/off switch into consideration and with POWER OFF test it for continuity.

15. xv

    If no 120 at the transformer input, and so your power cord or plug is the cause and you have to examine it and test information technology for continuity (unplugged of course)

16. 16

    Yous can purchase transformers, and seedling sockets from your local electrical supply store, maybe even Radio Shack, or you can search the spider web and there are many places that handle these parts.

• 1. Seriously consider replacing "Quartz-Halogen" and Halogen fixtures with CFL blazon fixtures instead of repairing them.

Thanks for submitting a tip for review!

Advertizement

• Exist very conscientious when trouble shooting these lamps, the hot lamps tin cause severe burns in a fraction of a second.

• Alert!!UNPLUG THE FIXTURE FROM THE WALL OUTLET, DO NOT WORK ON THESE STEPS WITH FIXTURE PLUGGED INTO Ac POWER. Except for testing, and performing the voltage measurements with the Multimeter / VOM.

• These fixtures, when inside homes are notorious for starting fires. They burn extremely hot and can readily reduce drapes, etc. to "kindling" in a very short period fourth dimension.
