Old or new, it seems that just about every house has a light switch that may not work. It can drive some people crazy. But, is it a big deal? It could be. But, it’s most likely not. Here are the five possible explanations for that inoperative light switch.

1. Burned Out Bulb
   If a switch is turned on and nothing happens, the first step is to see if all the other lights in the area operate with other switches in the space.  If one light does not work and it seems logical that this switch should work it, it’s quite possible that a bulb is out.
2. For a fan that is not currently there
   If you’re in a room and the switch turns on the light in the middle of the room and there’s another switch right next to it that does nothing, it’s quite possible the switch was installed that way so a fan could be added in the future with less effort.  This is common, even in new builds.
3. For a wall socket you can’t access
   Sometimes a switch may control a wall socket.  This is very common in living rooms in homes built before the 70’s.  It’s also common in master bedrooms of newer homes that may have switches on the wall on either side of an area where a headboard would likely go for a bed.
4. An outdoor light or attic switch
   Switches near the exterior or the attic access often confuse people.  There are multiple reasons for this.  One reason is if a switch is for the exterior the light fixture may have a photo-sensor on it and it may not engage during the daylight.  It’s designed to not come on then.  Another area that confuses people is when there is a switch in a closet that doesn’t appear to do anything. Often this may just be for the attic.
5. It is not wired correctly
   This is the most feared issue, but also the least common issue.  Certainly, a switch that is not working could be wired incorrectly.  But, unless it is a flip house or there are signs that other DIY work has been done, more often than not this is not the issue.

There may be other reasons.  But, these are the most common reasons why light switches do not work.  If you have questions about a switch feel free to reach out via email or on our Facebook page.  Let’s see if we can help you identify why you have an inoperative switch.  It may not be what you think!
