Question about Weber Genesis Silver B Grill

4 Answers

Low burners, low heat

My grill is about five years old with never a problem. Now it wont develop much heatg and if I turn on the second and third burners it has a tendency to blow out.  It was this way before I refilled the tank and is again this way with the tank refilled.
  I am afraid to fiddle with the flow limiter valve or whatever they call it on the tank unless it is safe to do so.  Seems like it is not a tank problem anyway if the problem persists after the tank was refilled and with the spare tank too.
  Thanks,
 Jane

    Full tank of gas and used two different full tanks but it refuses to heat beyond 300 degrees and the flame goes out if the two right burners are turned on. I've replaced the regulator once and that seemed to do the trick but after a year the problem is back. Are these regulators faulty?

    Never had a problem... now all three burners are on and the heat won't go over 350 after 45 minutes.

    Gas is not flowing adequately to the grille

    1. this grill was given to me about 10 years ago new and it has always had difficulty heating to 500+ degrees.I know this because my fathers grill which is the same model heats to 500+degrees in minutes where mine can take up to an hour or much more depending on outside temp.I have replaced the regulator,I've cleaned every componet on it.I've even purged the air out of the gas tanks and nothing works.Please advise

    We had almost exactly the same problem and tried a number of things, including cleaning insect screens, cleaning burners, refilling tank, etc. None of these suggested solutions solved the problem. Through a process of elimination I concluded the gas regulator had probably gone bad. A replacement regulator (different brand) at Home Depot cost just under $17 and the grill is now working perfectly again.

Hi! All
Check temperature with an infrared thermometer. Ask around, as a friend, co-worker or neighbor may have one of these touch free thermometers. If cleaning cob webs out of the gas burners does not increase the temperature, then replacing the gas regulator with a different brand sound reasonable. A pressure check using a proper gauge is the best solution.

My Weber Genesis Silver B is 7 years old. I experienced a similar problem this spring whereby the temperature would not go beyond 300 degrees even after 1/2 hour of pre-heat. One day after pre-heating I accidently dropped the lid from about 3 inches height and noticed the needle on the thermometer jump to over 500 degress. Turns out the problem is the thermometer, not the grill. Now I just give the lid a little smack from about 1 inch to unstick the thermometer.

I find I have the same problem in the winter, but not in the summer. Seems the cold air causes the gas to settle. Try taking the tank off, turn it upside down a few times, and hook it back up.

If you turn on the gas too fast with the newer tan systems, it can make the system think it has a leak and slows the gas flow down. Use proper start up procedures. Call Weber to walk you through them.

My 1100lp when burners are on low flame is to low and make squeeking noise and if a slight bit of wind will blow out flame. I cleaned burner tubes and replaced regulator with factory parts will heat up on...


turn off the LP Tank, disconnect the hose from the tank and wait 5 minutes. Reconnect the hose and turn the tanl valve on very, very slowly, until it's fully open. Light each burner and turn it to high. Wait for the burners to heat up and turn them down gradually to low. If flame height on low has returned to normal, the problem is solved.

If that didn't solve the problem, the air shutters on each burner may need adjusting. Consult the installation instructions that came with the new burners for the proper setting or consult your Owners Manual.

If it's real real cold outside, it's not unusual for the burners set on low to have a problem. The only solution to that is let the grill preheat well, before turning the burners down. Also, grill with the hood closed on low, if it's a windy day.

Hope this helps you and gets you back to grilling again.

My 3 burner built in has been a great, very hot, grill over the years. lately however it takes forever to heat up and the flame seems very low. ANY HELP OUT THERE


It could be a couple of things. First you could be low on propane or natural gas depending on what you use. The second thing is that over time the little holes in the burners clog. You can poke them clean with a toothpick. Or if they are rusted you will need new ones which you can find from an appliance parts dealer or manufacturers website.

Rear Burner is hotter than the front burner on my Weber Grill


Since the grill is 15 years old, it is probably time to rebuild it. Replace both burners and anything else that is not working properly

Very low flame, like very little gas is getting thru, tank is ful


Okay, what you are dealing with is called "vapor-lock". The way these grills need to be turned off is, close the tank valve first and after the burners go out, then turn the burners off. The way you are doing it is trapping the gas and you are getting a weak flame. Fortunately this is an easy fix. First, light the grill by turning the gas valve open, then turn the burners on to light the grill...as soon as that is done, close the gas valve on the tank then turn the burners off. Repeat this procedure until you get a good flame. If this procedure hasn't fixed the problem after the third time, you need a new regulator and regulators are easy to find in any home improvement store like Lowe's or Home Depot.

Low flame


Either ;
1 your valve is not opening on your tank,
2 your regulator is bad on your tank, or
3 your out of gas.

Unless your second burner is going fine then you have :
4 a bad burner valve control not opening or
5 Some cobwebs inside the burner blocking the gas flow.

If this helps you please rate me with as high a mark as you can. Thanks for using Fix ya and Good Luck

Flame low on grill however the flame is high on burner


Had the same problem. Belive it or not i basically follow the turn on instructions. Disconnet the regulator, let it stand for five minutes, the reconnect and turn it on 1/4 and turn the burner that is at the end of the line. (in my case the is the first one on the left).

Gas grill lights but doesn't get very hot


I had this same problem especially when the tank on my 5 burner 2 year-old Kenmore was about half full. The solution above fixed it. I was used to opening the gas fully, turning one burner to high and clicking the button. If I would have read the front of the grill I would have seen that this was incorrect. I turned off the grill completely, unhooked the regulator and reconnected it. With one burner on high I began clicking the button BEFORE I turned on the gas. I slowly turned the gas on one quarter turn and it lit up full flame. I slowly turned the gas another quarter turn and lit the second burner. I slowly opened the gas all the way and lit the third and so on. That did the trick!
