How To Fix A Gas Fireplace Making Rattling Noise When Off

1. Shut Off The Gas Supply

If a gas fireplace is making a vibrating noise, it’s time to shut off the gas supply.

To do this, you are going to have to remove the front grille and access the valve. This can be turned off by putting the gas valve in the off position.

If you wish, you can also turn off the gas from the main unit.

This depends on the property and how the gas supply is set up.

It is important to note, any work being done on a gas fireplace has to start only after the gas supply is shut off.

This is essential for your safety.

2. Access Fireplace Blower

If there is a noise from the fireplace, it is often associated with the fireplace’s blower fan.

The blower fan is what manages the airflow and ensures everything functions properly. When this starts to break down or becomes dirty, you are going to start hearing all sorts of noises.

This can include a fireplace that starts making clicking noises.

When learning how to get rid of a gas fireplace’s rattling noise, it’s important to pay attention to the blower fan. This is likely the root cause of the issue.

You will want to keep the grille off and get to the blower fan.

3. Clean Using a Vacuum

Once you see the blower fan, it’s time to take you a vacuum.

There is dust that can start to build up on the surface of the fan. This will lead to blockages that restrict airflow.

You have to make sure it is cleared out with the help of a strong vacuum.

Also, take the time to wipe the surface down and remove any excess debris that is found on the fan. This is a must.

If you don’t do this thoroughly, the problem will persist. This is why the rattling is happening.

4. Check for Wear and Tear

It is also smart to look for any wear and tear on the blower fan.

Sometimes, an aging blower fan will also start making noises because it is losing its structural integrity. This can cause it to sway inside the gas fireplace or start falling.

When this happens, the blower fan will move and rattle.

As a result, you end up hearing the rattling noise from a gas fireplace. This is why it’s important to look at the structural quality of the blower fan during your inspection.

If it’s broken, it’s time to replace the fireplace blower fan before putting everything back. This is a must to get things to work again.

5. Re-Test Fireplace

The last thing to do is to re-test the fireplace.

Put everything back together, turn on the gas supply, and see if the rattling noise is still coming. This is how you stop the rattling noise from a gas fireplace.

It’s a simple process and your eye has to be on the blower fan.

Final Thoughts

These are the things to look into when you have a gas fireplace making rattling noise when off.

If a gas fireplace is making a rattling noise when off, the most likely culprit is the blower fan. It’s common for the blower fan to break down, become loose, and/or need cleaning. To fix the issue, turn off the gas supply, remove the front grille, and clean the blower fan using a vacuum. Also, take the time to tighten the blower fan and check if it needs to be replaced.

This is a must if you want to get rid of the rattling noise.
