Noisy pressure regulator

Why after a month does my regulator vibrate and have a high pitched hum, increasing in volume as more gas is used? This is a normal outdoor gas grill with a 20 pound cylinder.

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.

    Not true. I have tried repeating the regulator, tried different days with different weather. Still have the hum.

Gas very slow to come after valve opened - grill connected to natural gas. After waiting up to 1 hour gas eventually comes and the grill will light. Wait time becomes increasingly longer with each use


Unhook the regulator, and open valve momentarily to see if gas is present under any pressure.
DON'T BE SMOKING. If gas hisses out, Replace the regulator with a new one.

Regulator uses springs and diaphrams. Either the spring is weak or the rubber diaphram is stiff or (oil contaminated) swollen and sticky. DON'T try to repair it. Not worth the risk!

Either way, the only thing between the gas supply and the grill is the regulator. Have it replaced.
DO NOT OPERATE WITHOUT A REGULATOR

Appears that connection vibrates and makes noise


When you say "connection" I am assuming you mean the hose and regulator and the regulator is humming. This happens under some very specific conditions, and is usually not a problem. You can replace the hose and regulator, easy to do and inexpensive, and see if it stops.

Regulator vibration


Hello,
If you are using a disposable propane bottle, make sure it is not horizontal when it's hooked up. It should be at a 45 degree angle or higher. You may be getting liquid out of the bottle (instead of vapor) at the angle you have it hooked up. Hope this helps. Douglas

How do you raise and lower the gas or tempreture?


Check to see if the gas regulator connected to your tank has a dial on it? Some have low med high settings. If it has no dial, the center of the regulator may have an adjustment screw, remove outer cap and turn screw clockwise in 1/4 intervals to increase pressure until desired flame is reached.

Barbeque is making a loud high-pitch noise. Can't


The diaphragm inside the regulator is vibrating; that is what is making the noise you are hearing. You could go out and buy a new regulator, but first I want you to try something. What I want you to do the next time you light the grill is to not open the tank valve all the way...only open it about 1 1/2 turns and light the grill. If the noise goes away (which, most likely, it will) then the easiest way to correct it is just to not open the valve all the way. Normally, all one needs to do is open the valve halfway and the grill will get plenty enough gas to give you a really hot cooking area.

Or, you can go get a new regulator.

There is a high pitch that people over approx age 30 cannot detect. My son and daughter complained of a high pitched noise coming from our gas grill, but I could hear nothing. I turned the gas tank off,...


What they are hearing is the regulator. There is a diaphragm in the regulator that is vibrating due to the rush of gas flowing through it. This is easily corrected. First, the next time you light the grill, turn the tank valve only one quarter to one half of a turn and light the grill, once the grill is lit, if you have trouble bringing the grill to the temperature you want, you can open the tank valve more and the noise shouldn't start. The reason the noise won't start then is because by that time, the regulator's diaphragm is at the temperature of the gas flowing through it and, subsequently, will not vibrate. If the noise starts again, you can go to just about any home improvement store and get a replacement regulator.

Regulator hums when in use and barbeque gets excessively hot


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.

High Pitched Humning Noise


It is the regulator trying to vent off with a restriction. As long as it is working it will be ok to use but I imagine its days are numbered.

Propane Regulator Adjustment


Remove the plastic cover on the center of the regulator. To increase pressure setting, turn the plastic disk beneath with a screw driver. 1 turn clockwise increases the pressure 1/2" water column.
