The fan in my oldest's room is running slow. My youngest's has the same exact fan. Swapped the fans, the youngest's fan in the oldest's room runs slow as well. Oldest's fan in youngest's room runs fine.

What could cause this?

    This sounds like an electrical problem in that circuit(in the walls). If you don't know much about electricity, get an electrician there very soon. Turn off the breaker if at all possible. Might just be a loose connection or something else, but it could heat up much more than is safe for you. It sounds like a low voltage problem, instead of 120 volts, that circuit is below 100 volts.

1 Answer 1


You narrowed it down to

1- it is not the Fan

2- it is location related

since you replaced the fan, you did some wiring in the ceiling part, tug on the wires to make sure they do not come out.

Next probable problem source is the wall switch.

Open it and tug on the wires making sure they do not come out (turn OFF the breaker).

If all looks fine replace the switch.

    There are way two many things that could be the problem to jump to the conclusion of a wall switch including series wired , and bad connections .

    It might be a portable plugged in fan, not a ceiling fan that requires work. #1 and #2 is right. Type of fan 50/50.

  • @EdBeal the conclusion is perfectly logical, but might be hard to understand for some. And it is not internet electrician based.

  • @crip659 OP said it is a ceiling fan, so it takes some skill to replace.

    @crip659 It does, in the tabs, unless they are wrong
