SOURCE: have a broan n688 ceiling exhaust fan in bathroom

First turn the power to the fan OFF. Take it down from the ceiling by removing the screws holding the cover on. Then remove the screws holding it to the ceiling. Then unscrew the screw caps that twist (connect) the wires from fan motor to the house wiring. Do a general clean up on the fan. Use an old paint brush to get in the hard to get at places. Rotate the fan by hand. If it does not rotate freely, put some oil on the shaft where it goes into the motor, and put some on where the shaft comes out the back. If it still does not rotate freely, buy a replacement and install it.

Not likely, Just a condition of the location of the vent and the wind direction.Putting a secondary larger hood over the outside exposure will sometimes help alleviate this.

SOURCE: Replace motor in Broan 678 bathroom fan

I ran into the same problem, Lowe's carries Broan exhaust vents. They had both a replacement motor for all generations of 678 fans for $18, and they also had the latest generation of the complete unit for $40. I bought the complete unit, which included the fan I needed. Just unbolted it from the new bracket and bolted it to the old one. The new light housing, trim piece, and lens also interchanged. The existing one was old and yellowed, so this made for a huge improvement. All done from in the living space as well.

SOURCE: my bathroom Broan exhast w/light

remove the cover and clean anything in the vent , check the fan for anything that could be touching it, as the back draft comes through the vent, something could just be touching the fan blade as this draft makes the blade turn slowly, which would create a ticking noise

Wet ceiling from my bath exhaust fan, how to stop?


Probably due to 1 0f 2 things...
1- Not enough power in the exhaust fan to take out all the mist /steam from the shower.. or

2- Condensation build up due to too much steam at one time.
(especially if fan is NOT ventilated properly)

If you have access to the fan, see if the label states the CFM 's it can remove. May not be enough for the size bathroom you have.

Both of these can be solved by installing a larger capacity fan system. Make sure to vent it to the outside of the home too, since venting to a cold attic area (in winter) can cause even more condensation to drip down.

Should i use the same drywall in the bathroom as in the rest of the house?


I recommend using MR (Moisture Resistant) drywall for the bathroom, and possibly for the basement if there are moisture issues. It is not much more expensive, and it can save you a big headache later

My quiet bathroom fan makes a roaring noise


The roaring noise is probably the fan blades (looks like a hamster wheel) are worn out as it rotates on the spindle/shaft.

It may be a problem with the 4" exhaust ducting, that connects to the exit part of the fan, has come loose. Theres a damper (kinda like a flapper) at the fan/ducting joint may have broken off and may be sitting sideways in the ducting flapping around inside the duct.

At any rate I highly doubt its wiring. Sounds like its time to pull the fan cover off (turn the power off first via the wall switch or the service panel breaker would be even better) and look at the fan blades. Clean off any dust bunnies, lint, etc. and turn the fan back on. Did the noise stop?

If nothing looks out of place and it still makes noise you'll have to get in the attic and remove the ducting from the fan and see if theres a problem at the connection there. Maybe a squirrel put its bedding in the ducting? It happens.

Could be lots of reasons for the noise but wiring it wrong wouldn't cause roaring. The fan wouldn't work, or worst burn up, if wiring was the issue. The problem is the more than likely the fan blade assy is worn out or something is restricting the air flow in the ducting going to the outside of the house.

My Bathroom Extractor Fan does not work properly and for some reason the bathroom smells of cigarette smoke when the upstairs neighbours are at home!! Our landlord say's this is not possible!!!


Yes, very possible!. The bathroom fan is connected together, and the upstairs one is down-drafting to you. Have the exhaust checked for blockage, or buy a fan that has a built-in damper that closes the exit when not in use.

New bathroom venting in basement bathroom.


Install a window mounted exhaust fan if you can discharge to the outside of the house surrounding atmosphere.But undercut the door of the batroom to allow air coming in into the room.Alternatively firt a door grill 600 x 150 mm size which is more expensive.THe size of the fan should be 50 to 100 l/s of air flow.
