Why does the bedroom have a light switch but there is no light in the ceiling?

Tuesday, August 14, 2018

All habitable rooms of a home are required to have switched lighting near the entry door. You need to be able to turn on a light when you enter a dark room to avoid a fall or bumping into furniture. But the building code allows that the switch can be connected to a wall receptacle that a lamp can be plugged into for the necessary light. It used to be common for builders to have switched receptacles in bedrooms, but is rarely done nowadays. A switched wall receptacle might also be used for the required interior lighting at the front door into a living room. There is, however, one exception: kitchens and bathrooms must have installed lighting.  

   So it is likely that the switch is connected to a wall receptacle in the bedroom. It is usually connected to just the top half of a duplex receptacle. We suggest that you put the switch in the off (down) position and plug a corded light into every receptacle in the room until you find one that is dead. Then turn the switch on to confirm it’s the one.

   If no receptacle in the room is dead with the switch in the off position, try throwing the switch to the on position and testing all the receptacles again. It could be that the switch was installed upside-down. If you still have no luck, then the required switched lighting for the room is missing.

   There are also two complications that can arise in remodeled older homes regarding switched bedroom lighting:

1) If the bedroom has a switched wall receptacle and wiring was run for a ceiling fan with a light kit on a separate circuit as a later update, it may appear that the switch is not functional. Check to see if the switch goes to a wall receptacle. It is likely that the circuit for the ceiling fan is always live and it is simply controlled by the pull chains or a hand-held remote.

2) If there is only one wall switch and it controls a ceiling fan, but the fan does not have a light kit, then the required switched lighting for the room has been removed. A light kit needs to be added to the fan, or the fan replaced with a ceiling light.
