We live in a two bedroom town home, and within the upstairs bathroom, an exhaust fan is located in the ceiling (but not above the bath tub/shower). There is a wall switch containing 3 switches: one switch is for the "primary" light, the second switch is for the fan, and the third is for a "heated" light (we rarely, if ever, use that).
Recently, we needed to have some repairs done to or roof, and it seems that ever since then, the exhaust fan is constantly running. The switch for that fan does nothing to turn it off.
About a month or so ago (fan again had been running, but apparently that was "normal", as it eventually stopped), after "disabling" current to the bathrooms (via the fuse box in the garage), I did take apart that switch, but did not see anything definitive there. I also removed the cover to the fan in the ceiling, but again saw nothing definitive there.
There is some small stains in the ceiling around 3 sides of that cover to the fan, but nothing serious (as far as I can tell). I also know that when they did the roof repairs, the contractors did need to "move" some vents, but I do not kn ow which ones.
I will send an EMail to the contractor about this, but can you folks provide any guidance, assistance, and/or insights as to why this is the case?
