Ceiling Fan Make Scraping Noise: Common Causes and Solutions

Ceiling fans make a scraping noise, which is not the story of the one house; almost all of us encounter this issue and rush for quick troubleshooting. This is why we have covered the ten basic reasons and their hacks for your ease here.

1. Dirty Fan Blades

Dirty fan blades can be a big cause for a fan to shake and wobble as they throw the fan blades unbalanced. Clean both the sides of the blades carefully using a lightly wet cloth. The upper sides of the blades will be dirtier than the bottom ones, so don’t stand directly under the fan when cleaning the blades. Wipe any moisture from the blade surface as most blades are wood composite or particle board materials and, thus, prone to be damaged by moisture or water.

2. Warped or Damaged Blades Of Fans

Ensure that the fan’s blades are straight and warped and not damaged otherwise. Damaged blades create noise and cause shaking during the fan running. These damaged blades put unnecessary pressure on the motor and fan mount. Thus, it would help if you changed these fans’ warped or damaged blades. If this is the issue, you can contact the fan manufacturer company to ensure that you get the perfect match.

3. Unbalanced Blades Of The Fans

Another reason for the noisy fans could be the unbalanced blades. There is no good reason for the unbalanced blades, but it could be a reason for a noisy fan. It’s very easy and simple to balance the fan’s blades as it requires a simple balancing kit. Normally these kits are given with new fans, or you can get them from hardware stores. These kits usually consist of plastic clips and stick-on weights, which help balance fan blades.

 

For the balance, you can set the clip on the rear edge of a fan’s wobbling blade. If the wobble is finished, you have the problematic blade; if not, try other blades one by one. Switch off the fan and try the clip on different positions of the problematic fan blade to check which position is the most effective in reducing the wobble and shake. After deciding the accurate position, stick the weight there with the clip. You can try another weight if necessary. Can you check whether your ceiling fan makes a scraping noise or not?

4. Loose Blades Of The Fan

Different ceiling fan parts can be loosened and create noise with time. Firstly, you must check where the blades are mounting to their brackets. Fan blades are attached to the brackets with the screws or similar fastening systems. It can be keyholes that fit over pins, or it can be studs on the brackets. Just tighten the loose parts of the system of the blades.

A Tip: Screws of some blades can be of size #3 Phillips screwdriver tip. Normally the standard size is #2, and you can easily identify #3 screws by a square space in the center of the screw tip, with a flat area on its head. If you try using the #2 screwdriver with #3 screws, you will strip them. 

5. Loose Blade Brackets Of The Fan

It is where fan brackets mount to the rotating part of the fan’s motor assembly. The brackets are normally attached to the fan’s motor with screws or bolts. So, it would be best if you got them tight with the help of a proper screwdriver or a wrench. The blade brackets themselves can also be loosened, so your ceiling fan makes a scraping noise.

6. Poorly Settled Motor Cover

If your ceiling fan makes a scraping noise, it might be due to poorly positioned motor covers. It can be because blade brackets are dragging on the fan shroud or motor cover. If this is the scene, you can handle the situation by losing the cover’s screws, carefully adjusting the position of the cover, tightening the screws back, and ensuring that the blade brackets are tight enough and not rubbing against the cover.

So, do not use any tools for these screws, as these can be over-tightened in this way, and chances are there to crack the glass of globes, etc. Now even if the tightening of these fixture parts with their screws is making them snug, the thing you can do is to add a rubber cover around the neck of the shade or globe. Now reinstall it with its screws and check. The fan makers also have sets of rubber silencer bands or coverings included in the package for the user to avoid these types of issues without any professional help.

The mounting screws that join the fan to the electrical box may also loosen over time and become a reason why ceiling fans make a scraping noise.

As you would be working with metal tools around the wiring, it’s not enough to turn off the wall switches. Now loosen the canopy cover screws and put the cover aside.
