Mayo Gas Info

I have a natural gas furnace and noticed that on an intermittent basis it makes a buzzing sound. At first the buzzing sound didn’t happen that often, but now it is happening more frequently.

The furnace will buzz for several seconds and then stop. Then at some random point it will buzz again for another few seconds. This only happens with the furnace is actually running.

The furnace is still producing heat. In fact, apart from the buzzing sound, it is working normally.

Well you got all the smart answers, now I’ll try to actually held you.

Your gas furnace has a blower motor. There usually is a metal access panel over the internal parts of the furnace. Next time you hear the buzz, go to the furnace and put your hand on the panel, I’ll bet it is vibrating when the blower motor is working. If it is not that panel, try a different panel.

When you find the buzz panel, you’ll have to secure it so it doesn’t vibrate. If this doesn’t fix your buzz noise, you may be forced to call a repair man to do more investigating, but it’s usually some that gets lose when it gets warm. I would be surprised if it were not just a lose panel cover.
