Troubleshooting Attic fan noise

Below are some tips that you can initiate to see your home cooler work again;

1. Diagnose the exact problem with your Attic fan by disconnecting it from the power outlet

This should be the first thing to attempt before touching anything. Your safety matters are a lot more than the fan itself. I don’t know the exact type of Attic fan you are using, but make sure the unit is powered off. Under this step, you should try to diagnose whatever is eating your fan.

However, sometimes you may be forced to power the device on and observe the problematic part. Turn it off when you want to tackle anything that you think is interfering with the normal performance of your fan.

2. Substituting ball-bearing

This could be another action that you can take to reduce annoying noise from your Attic fan. However, we have some folks’ Attic fans that don’t feature ball-bearing. Therefore, if you have, then your device should be working smoothly.

Things will start to go wrong immediately after this component breaks or are worn out; the noise issue is the common symptom. For an amateur, this complication can be a bit challenging to fix. If you don’t wish to encounter hassles, my advice to you is to purchase a new fan ball-bearing; but remember to get a compatible model.

3. Inspect the Attic fan blades

After powering the fan off and it has settled, it’s now time to inspect its blades. Wait until the blade rotations are over; to avoid minor injuries. Check if there’s any bent blade; it may be the one hitting other parts. The only precaution you should be keen about under this step is to ensure the blades are not turning around.

Count yourself lucky if you meet unbalanced or bent blades; the fix will be straightforward. Just twist and balance them to the right position. These fans come with their balancing kit, if there’s one, don’t hesitate to use it. Alternatively, you can install several metal washers to correct the blade(s). Take a tape and securely hold the blades in the correct position with the help of the washers.

However, if the condition of the blade seems to be extremely bad, it’s time to change it. Failure to do so will worsen the situation, transmitting the same problem to the neighboring blade.

4. Tighten the mount of the fan and other loose parts

You may realize that loose parts are the ones making your fan produce annoying noise. This tends to be the most common culprit for noisy Attic fans. Solving the challenge is straightforward as you only need to ensure parts like the mount are tight. The fan mount can get loose, mostly when it is mounted from the roof.

On the other hand, we have some parts that could be producing vibrations and wobbles; these are unbearable noises that you should do away with. One of the tools that you will require here is the screwdriver to properly tighten the mount screws and loose parts. Confirm whether this was the real culprit for the noisy Attic fan by powering the unit on and paying close attention.

5. Swapping the motor can be another reliable way to minimize Attic fan noise

After lubricating the motor and there’s nothing positive from it, then the remaining thing will be to dispose of it. Nothing is permanent in this world, and therefore it is advisable to opt for a compatible fan motor. The model of the new motor should match that of your Attic fan.

However, attempting to replace the motor on your own can be a bit complicated for some people. Replacing blades is a bit easy compared to the motor. Besides, a fan motor can be a bit expensive since it acts as the heart of the machine. I have seen some folks going for a new fan instead of replacing the motor; if you are deeply in love with your Attic fan, ten I am sure this statement isn’t making any sense.

6. Lubrication is necessary for some corroded parts

Here is another way that you can use to ensure your Attic fan incredibly works again. Like any other machine, this fan has rotating parts that I am sure sometimes can get rusty. Under this section, the fan motor becomes the most affected component that should be checked.

In such a scenario, you are advised to detach all the blades from the unit and run it solely. Pay much attention to observing if the fans were problematic or the noise is emanating from the motor. If the naked fan still produces noise, then automatically the motor is problematic.

The main causative for a noisy motor can be aging. When did you lubricate the item? If it has served you for some years then you should opt for a replacement, but consider lubricating it first. Let throwing it be the last idea in your mind. Lubricant spray can be the best product to consider if your Attic fan works properly.

 Lubrication is necessary for any machine appliance and the Attic fan is included. Doing so comes with a lot of benefits like extending its lifespan.

7. Purchase a quieter Attic fan

There are different options of fans from the Attic brand that can still work for you if the current one isn’t quieter enough for you. Don’t struggle with a machine that is outdated while your friends are upgrading to a recently produced fan. Therefore, if you realize that a certain fan has served you for more than four years, prepare to purchase a quiet one like living ILG8SF10V.
