Suggest you take the tank and trade it in for a new one with one of the propane companies like blue rhino. it's about $15 to $20 and you get a brand new full tank.

Hi, my model 4651330 worked great the first time i used it. Now I can't get the grill to completely light. It seems like the gas is not being pushed through.

Turn the gas cylinder OFF and disconnect it from the valve. Wait 5 minutes and reinsert and screw the tank valve in. Once it's completely seated, turn the valve ON VERY, VERY, SLOWLY (Slow motion, slow). One the valve is fully open, light the burner. Have the burner flames returned to normal? If so, you just solved the problem. If it didn't, turn the tank OFF and remove it. Then remove the cooking grates and lava rock, if you're using lava rock. Inspect the burner closely, as it may be clogged. It may even require removing the burner from the grill to clean it properly. Also, check the venturi valve. That's the thing on the side of the grill tht's part of the burner. It mixes air to the gas, so that there will be complete combustion. The venturi valve may have been moved by accident or it's clogged. The correct position of the fan like opening is 3/4's of the way open.

I have assumed you have made sure there's still gas in the cylinder.

Hope this helps you to troubleshoot and solve the problem.

When I turn on the gas and ignite, some of the burners are huming. Why?

Are they humming ot does it sound like a jet engine? If it sounds like a jet engine, the venturi valves on those burners my be clogged and need cleaning. You will have to remove the burners to do this. The Venturi Valves are on each side of the burner on the open end of the burner. They will look like slots.

If in fact they are humming. Turn all the burners OFF and the turn the tank valve OFF. Disconnect the hose from the tank and wait 5 minutes. Reconnect the hose to the tank an open the tnk valve VERY, VERY SLOWLY (Slow Motion, slow). Once the valve is fully open, light the burner farthest from the tank first and tunr it to high. Does the flame height look normal. If so, light the remaining burners the same way. Do all the flame heights look normal and has the humming stopped? If so, you solved the "humming" problem. If not, you will need to replace the grill's hose/regulator assembly. They are not expensive and you can find one at any home center or hardware store that sells gas grills and accessories. Take you old one with you for comparison purposes. Afte you replace the hose/regulator assembly, open the tank valve as I described above.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks & Happy Grilling!!

Can a gas grill freeze and lose its gas

No the grill can't freeze and lose it's gas. But the regulator could and stop the gas. If that's the case, take a bath towel soak it in hot water, ring it out and quickly wrap it around the regulator. If i was frozen, this should thaw it out and the gas should start flowing in several minutes. If the tank valve was turned OFF in the winter and you just turned it on. Turn the tank valve OFF and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Now, turn the tank valve on VERY, VERY SLOWLY (slow motion, slow). Once the valve is fully open, light the burner farthest from the grill and turn it to the highest setting. Does the flame height now appear to be normal? If so, light the remaining burner(s) following the same procedure. If all burners have returned to normal, you solved the problem. Just remember to always turn the tank valve ON very, very slowly.

Hope this helped you solve the problem. Please let me know. Thanks and Happy Grilling!

Burners run cool when set on high, when all but one burner is off, the single burner opporates correctly. Grill worked fine before.

There have been issues lately with the way regulators are not drawing gas out of the cylinders properly, and how some of the newer grills are not heating properly.

The issue with them not heating properly goes back (usually, from just what I have observed) to the position of the gas knobs at the time the cylinder valve is opened. On some grills, if the gas knobs are open when the cylinder valve is opened, the burners will not get the maximum amount of gas to all burners, but the performance of one burner is enhanced if the others are turned off, and this sounds like what's got you.

Turn the gas cylinder valve to the off position, and bleed the gas pressure down at the burners. Close the burner valves. Slowly crack open the tank valve, and work it slowly to full open. With the grill lid open, select and light one burner. If it operates properly, light the other burners. If the first burner does not operate properly, repeat the procedure. If you cannot operate your grill like it is supposed to, the issue may fall to the regulator. If the regulator is an older style, it may not actually be fully compatible with some newer cylinders. This seems to be a newer phenomenon, and seems to be found with the type of cylinders that are swapped for a refill. If this is your case, you will need to upgrade to the newer regulator.

Best regards, --W/D--

Grill will not light

If there is no gas check the tank, If the tank is fine look at the regulator. It has to be flat, because of a valve inside. This is a safety device incase of tipover.

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.

Humming noise

1st. Are the humming evident when the flame ain't burning? Listen carefully. The control(knob) consists of a valve that regulate the supply of gas to the burner. Check each knob(valve) individually for noise. If noise is evident on the knob(valve) contact your dealer for service or replacement of valve.
2nd. Check the gas regulator. That will be the unit that is exiting the gas bottle. Noise might be evident from the regulator due to the gas being controlled. If excessive noise is evident. Service or replacement of the unit might be necessary.

Noise / vibration from gas regulator

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.

Frozen valve

I had this problem recently. Try turning the valve the other way (seems odd, i know). This worked for me. Also, if this doesn't work do not do anything too drastic on it because it can explode.
