Question about Casablanca Fan Stealth 3211T Ceiling

Scraping sound inside casablanca stealth fan

An momentary metal-on-metal scraping sound only at very slow speed when the fan is starting or stopping. Or when I turn it by hand. Obviously related to the rotation - there is one particular point in the rotation where the scrape occurs. The scraping does not involve the glass or the exterior housing.

The fan is several years old, and I think the fan blades are not perfectly level with the motor housing any more, So until the blades start to "fly" and level themselves out something (flywheel?) is hitting something at one point in the rotation. If I "adjust" the blades by hand to be more level this fixes it - once.

How do I find and fix this for good?

    I believe this fan has a design flaw. I have talked to service people who allege this -- the thinking is that the blades are too heavy for the design, and consequently fall "out of level", as described above, after a certain number of years (typically when fan is out of warranty, of course!). This flaw necessitates purchase of a new flywheel. I would like to hear from anyone else who has had this same scraping-sound issue, because i have had it happen twice in ten years, and I want to take the matter up with Casablanca, and yo might want to as well. Admittedly the flywheel is only $15.00, plus applicable taxes and/or S

    I have this same issue. I did correct it by adding small washers to sort of shim the flywheel and the housing but now its back. I have two fans. I only modified one unit about two years ago. Both are making noises now.

How do I op beeping of my Casablanca stealth fan Bulb is burnt and I removed he burnt bulb. would not top annoying beeping


Replace the bulb. If you are going crazy while getting a new bulb turn off the breaker for the room. A serious design flaw, I would complain to Casablanca if you have the time.

There is a scraping sound at slow speeds that appears to come from the front breaks. What is Causing the sound?


wear sensors on the pads-you need to pull one wheel and look to see how thin the linings are, better to replace them not than to wait until it is metal on metal and ruin a rotor.

Casablanca stealth fan light scrapes against blade surround


There are two probable causes. One, the light housing has been pushed/bent up into the rotating assembly, which is possible if the fan were ever removed from the ceiling and sat on the glass.

If it has never been removed however, the most likely cause is that the Allen Set screw on the flywheel has loosened allowing the flywheel to slip down the motor shaft. It's a purely mechanical problem and if memory serves, to get to the flywheel, you remove the light pan and it's right there. Find the set screw, loosen it enough so that the flywheel is easy to move up and down and raise it up a bit and then cinch it down tight. It's a fairly common problem and for the life of me I cannot understand why Casablanca would not use loctite on that set screw. I mean you pay $500+ for a fan, it should outlast you, right?

Right rear is making a sound of medal scraping medal. I believe it maybe the wheel bearings.


If it's a scraping sound, when does it happen? If it's when you hit the brakes, then it's likely your rear brake pads/shoes are down to the metal and are scraping. This can happen when you're not hitting the brakes, however. Bad wheel bearings are usually a moaning/roaring sound that increases as road speed increases. Ditto that for differential bearings - if they go out, you usually get a roaring noise that increases the faster you go.

Clicking sound


The fan should be replaced. The bearings are getting worn out.
