Christmas Lights Go Out

Ah yes, it’s Christmas time again! Time to decorate the tree with garland and Christmas lights. The glow of colored lights glistening throughout the house while waiting on old St. Nick. But what happens when the lights suddenly go out? Is Rudolf stealing the power to light his nose? Is there a power outage? Well don’t get too excited yet. Let’s examine what some of the probable causes are and how to remedy the problems.

  1. Check the Circuit Breaker or Fuse Feeding the CircuitGo to the electrical panel and check to see if any circuit breakers are tripped or fuses blown. Use a circuit tester to see if the outlet that the lights are plugged into is hot. If not and the circuit is on, turn the circuit off, remove the outlet, and check the connections to the outlet.
  2. Check the Fuses in the Christmas LightsIf the Christmas lights go out, it may be as simple as a fuse blowing within the light set itself. Located within the plug-in plug is a couple of fuse. They are hidden behind a sliding door that is clearly marked. Simply unplug the lights and slide the cover to expose the fuses. Remove the fuses and check them with an ohm meter. If there is no resistance, they are good, but if there is infinite resistance, they are bad and should be replaced.
  3. Check the Individual Light BulbsSometimes the Christmas light bulbs themselves are the troublemakers. They could be loose in the sockets and that can cause them not to light. A bulb could have fallen completely out of a socket or have a bulb wire bent to the side that isn’t making contact with the socket contacts. Usually you’ll have some replacement bulbs that come with the lights for just such an emergency. Replace the bulbs if needed.
