I live on the main floor of a 4 story condo building. I have a stacked washer/dryer unit in a small laundry room in my condo. Recently when I operate these units a big grinding noise is coming.
I called a laundry repairman, and he rightly identified that washer/dryer system is working fine, but the noise is coming from a motor located in the ceiling of the room that sucks out air to vent it outside. The ceiling is, of course closed (I think with drywall), so the motor is not accessible.
We confirmed that the noise indeed comes from this motor located behind the ceiling by pressing on the ceiling hard in the area where the motor is located and realizing that the noise disappears.
Looking for advice on how to fix this problem.
Most exhaust fans unplug from the inside and drop down once a screw is released leaving the original housing in place. The housing itself may be loose and vibrating against the joist and drywall causing the noise.
If that doesn't solve the problem bring the motor to your local hardware store and have them give you a new one as the bearing may be shot.
Robert nailed it in his first post. You have to remove the drywall and replace or repair the noisy fan. Replace the drywall with a hatch of some kind so it can be serviced again if required. It is actually very surprising that there is no access hatch in place already for something that would obviously need servicing sometime in its life.
Good Luck with it!
It's been my experience these type of fans can always become noisy. Yes you will have to access the fan/motor by cutting out the drywall. Ideally, the unit which houses the fan, should be mounted to the ceiling joists using either springs or strong leather straps so any noise coming from the motor will be absorbed and not transferred thru the building.
In addition, you can try cleaning and lubricating any moving parts.
Caution not to use WD40 on anything made of plastic or rubber. You'll damage it.
Hope this helps.

The key here is to install an access door or hatch as has been mentioned. These types of equipment need access for regular maintenance and repair. Both Rob and Jim indicated that in their posts.
A hatch can look OK as long as it is installed properly and the person cutting the drywall does not hack it all up.

I am extremely grateful for all the tips provided by the respected handymen. These have really helped me.
Actually, I found that there is an access door in the ceiling. I opened it and tightened two winged nuts that were a bit loose. Also, I noticed the sound originated from a ceiling light fixture which was vibrating when the laundry system ran. I tightened this too, the noise is gone now.
I am leaving this information on the forum because what I did together with all the tips provided by the very considerate and friendly handymen on this forum may help others encountering a similar situation.
