When Your Gas Grill Makes a Humming Sound

If your grill is making a low humming or whistling sound. Should you be concerned? Unless the sound is also accompanied by the smell of gas, the answer is no.


Humming noises aren’t uncommon with gas grills. Typically what’s causing the sound is the vibration of the rubber diaphragm inside the regulator. Any number of factors can be behind the vibration—outside air temperature, humidity, barometric pressure or even the gas level within the tank.


You may notice the humming sound comes and goes, depending on the weather. Although the sound may be alarming, it’s not dangerous.


So go ahead and let your grill hum. And if the mood strikes, sing along. We’ll never tell.
