Noisy Bathroom Fan

You might be on this page because your washroom fan is making a noise. Since bathroom fans are used for prolonged periods of time, they may become noisy. Mostly this is not a big issue but a simple fix. If a person is a little bit handy, the whole process can be done in under 10 minutes.

Here we will see two scenarios that can happen if your washroom fan is making a noise.

First One: Dust on the blades and fan housing

Just ask a simple question to yourself, when was the last time you had a look at your washroom Fan. Probably, if you moved to your home, a few years ago, then you will not have any idea when the fan housing was cleaned.

And the accumulation of dust is the main reason for fans to be noisy. You can save a good amount of money if you address this issue yourself. The simplest of the fan can cost you under $50 and can even go above $150, not to mention the bathroom fans with Bluetooth-enabled speakers which can be further up.

If you want to save money, just follow these simple tasks;

  1. Switch off the relevant circuit breaker.
  2. You will need a matching screw drive.
  3. Remove the fan cover. Juggle up the retainer clips and you will find it easy. Mostly you will have to press the 2 wires at two ends and take them out
  4.  Take out the single screw. Mostly fan is mounted on a metallic plat and is held with a single screw.
  5. Unplug the fan.
  6. Slide the plate assembly to one side and take it out.
  7.  Remove the excessive dust build-up. Clean the fan assembly with a brush, vacuum, or aerosol.

That’s it. Put back in the reverse order. It’s recommended to take as many pictures as you can take. This will facilitate and will help if you are stuck.

Give it a try, it should work.

Second One: Enlarged Diameter of the Wheel hole

Over the period of time, it can happen the plastic wheel might be worn out and has become loose. If so, it will wobble and touch the inside housing, and making noise. If so, continue with the above process and;

            1. Take out the push retainer clip or retainer washer sitting on the top of the shaft.
            2. Pull the plastic wheel out from the shaft.
            3. Replace it with the new one. Make sure that the flat portion of the shaft matches the wheel.

Once done, put back the fan assembly and you are good to go. If it’s not, buy a new kit or full assembly.

Tip: Before you start any project, always take as many pictures as you can. These can be very handy if stuck upon and will be helpful for sure.

Important: Before carrying out any electrical repairs, it’s always recommended to consult a qualified licensed electrician for best practices. This is merely information.
