Noise / vibration from gas regulator

Several times, not always, after lighting the grill, the regulator begins to vibrate and make a loud humming noise. I'm concerned that its unsafe. Other times, it works normally. Actually don't know the model so selected a "valid" option. Its a small two-burner grill similar to the current Spirit model but a year older. Suggestions?

    We're having the same problem and are not sure if its the regulator or something else, but its always there no matter what the temperture is. I did a thorough cleaning and its still there. Ocasionially it will not be there upon startup but then the flame stays on very low and wont increase. Thanks for any help.

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.

Gril makes aumming noise when lited

The diaphragm inside the regulator is vibrating against the outwear housing. usually this simply means it has some humidity built up inside and nothing unsafe. tap it with the handle of a screwdriver and that usually stops it. Many customers will replace the regulator because the noise sounds dangerous but it is only annoying.

Why does my gas dryer make a loud vibration noise?

Hey friend, I appreciate your post!

I understand that your Electrolux gas dryer is making a loud vibration noise and is also loud while tumbling. There are several components in your dryer that could be causing this noise. Based off what you are describing it might be an issue with your suspension rollers, motor, or pulley. Since it could be any of these underlying issues I would suggest getting a technician out to diagnosis and repair your dryer. Hope this is helpful. - Matt

AC Clutch noise and vibration

An A/C clutch will not make this concern happen, more likely the A/C compressor is begining to go out. The belt on the A/C clutch Assy. free wheels (spins feree on the pulley) when clutch is not engaged. If concern is not present with A/C off this means the bearings in the puley assy. ok. Once the A/C clutch is engaged it locks the compressor against the spinning pulley and turn the compressor chaft and spins the A/C compressor internal shaft. If you hear a loud "screach" when you turn on the A/C it means the belt slipped for a second, if it continiues to screach it means either the belt is loose or that the compressor is internaly locking up. I wouild start by checking the belt tension (if not equipted with and auto tensioner). You can also remove the belt and turn on the A/C and attempt to turn the clutch/pulley by hand, it should turn with a little effect but should not bind or lock at times if that happens compressor is bad.

Loud hum from under the hood. heavy vibration fron air filter all the way to top of engine

I think the loud hum is coming from the exhurst. The exhurst either has a cut/hole or the rubber holding the exhurst has removed. This will make the exhurst begin to shake and vibrate.
Turn on the car, go under the car, then ask someone to press the throttle. This will reveal where the vibration is coming from.
Keep me posted.
Good luck.

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

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

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 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.
