Regulator vibration The regulator on my Weber Baby Q is vibrating - loudly enough to hear a light humming sound. It (reg) is also very cold to the touch. The flame was still burning, gas supply is adequate, however I turned it off. I suspect the regulator needs replacement, but is it more than that?

The noise my be do to vibration. Is there any spot on the dishwasher where you can put your hand to temporary stop the noise do to vibration? I’ll continue my answer after your feedback.

I had the same problem with my volvo. I changed both axels as the should be both changed at the same time. No more vibration.

check the alternator , power steering belts

It probably is your radiator cooling fan. It will run until the car temperature drops to near level temperature The line vibrating is more than likely just vibration of the which is nothing unusual.Hope this helps;

You have the bottle valve opened all the way, the gas is rushing through the regulator making the diaphragm vibrate which is the humming noise you are hearing. With the gas flowing like that, you are basically preventing the ability to control temperature so the grill gets way hot. The best thing to do is to open the valve one full turn only and then light the grill...if you can't get it hot enough after that, then open the valve another full turn...you should never have to open that valve all the way...if you start having to do that then the bottle is almost empty and needs to refilled.

Sounds like tires.

there is a bad bearing inside that has worn out and causes vibration and excess heat, when it frees up it will spin quiet for a little then bind and vibrate again. need to replace bearing.

It is the color wheel. Impossible to do this yourself.

This is on the Weber site, under support. I have been experiencing the same problem and have not used it because of it.

Humming or whistling from the regulator: Outside temperature, humidity, barometric pressure, and the gas level within the tank may cause the rubber diaphragm inside the regulator to vibrate, making a humming or whistling sound. Although this sound may be alarming, this is NOT dangerous as long as it is not accompanied by the smell of gas. If the humming sound persists, a change in atmospheric conditions will eventually stop the vibration.
