I have a combination light/exhaust fan over my shower. The light and fan have separate switches. I replaced the switch for the fan a few days ago with a timer that has settings for 60, 30, 20, and 10 minutes, as well as an off button. I did this so I can set the fan to a timer to help exhaust the humid air from the bathroom - I have a habit of forgetting I left it on, and going to work with it still going full blast. Hence the timer. However, after I installed the timer, the fan is running much slower and quieter now. I know that running motors outside of their design speed can sometimes cause issues, so am I risking burning out the fan motor, or worse, starting some kind of fire in my house? The fan still moves plenty of air at the slower speed, but I am ignorant of how things like current, speed, voltage, etc., all play into something like this. Am I fine to leave the timer in place, or do I need to go back to the switch? |

The fan is a nutone combination fan/light. It looks most like their model# 668RP, but has more of a decorative flange around it. I can't get to it to check. I looked at the package for the timer, and it says incandescent only, so I guess I'll just need to exchange it. |
