Question about Weber Genesis Silver B Grill

1 Answer

I can smell the gas coming through. The igniter, ignites a small flame at the right end, but that is all. The flame does not light the burners. I did look at the burners, they look fine. Could there be a problem in the igniter itself? Thank You... Nancy

It's either the flame sensor or the gas valve.

The sensor senses flame and sends signal to the valve, the valve then sends gas through the burner/s.

If it's a thermocouple (looks like thisbefore installed) http://furnaceparts.com/eshop/products/thermocouple.jpg
then replace the thermocouple.
It sits right in the flame pattern and they usually cost less than ten bucks.

Why won't the burners light even when I smell gas and hear igniter clicking?


Bill, two things possibly going on here that are common with an aging grill. First you need to turn off the fuel tank and set it aside. you mention that a clicking can be heard when pushing the igniter button which usually indicates good battery but if you have never changed it you may want to just as a good measure. Unscrew the bottom and you should find AA or AAA battery behind it. Now with battery good and the igniter generating a fast load clicking sound you want to get down and follow the wire that runs from the the back side of the igniter push button down inside and usually under the burner tubes ending out at one end of each burner. What happens when you press the igniter switch is, an electrical current is sent down the wire and when it reaches the end the current jumps to the closest metal it can find creating a spark.so you need to insure that the end of the wire is close to where the flame is generated but not so close that that you cant see a spark. Make sure the end of the wire is bare and clean as is the area on the burner where it arcs Now do this to all for burners. Turn all the knobs on the grill off and connect the tank. Make sure the lid is open now, and slowly open the valve on the tank. I say slowly like a ten count from close to full open. what can happen if you crank the tank valve open too quickly or with the grills valves open a vapor-lock effect can be created greatly reducing the flow of fuel from the tank. Iv'e seen many of the uninformed return 1/2 full tanks due to this problem. If you notice week flame or no flame but smell gas ALWAYS SHUT OFF VALVE ON TANK IMMEDIATELY KEEP LID OPEN AND LET THE AREA VENT BEFORE TRYING AGAIN lest you be the one being barbecued. Good Luck

Brinkman second burner not lighting


Sometimes by the igniter there's a small deflector that directs 1 jet over to the gas outlet holes on the second burner. You can always get a butane extendo lighter and do it manually (or a match on hemostats)

A small wire from under the grill became unattached. I can't see where it reattaches and obviously the grill will not light. However you can hear the gas go on when I open the gas value.


If the wire is attached to the igniter behind the front panel, the other end has most likely come loose from the electrode that provides the spark to light the burner. You most likely will have to remove the cooking grates, flame tamers/briquette grates to get tho the electrode.

Rotisserie burner won't light


It could be a dirty or inop spark electrode. Also could be weak batteries in the spark igniter.

Before you start you should make sure that the ignition system has fresh batteries. The batteries are usually located within the igniter button but not always. Some BBQs will have a battery pack located somewhere on the BBQ and others you can remove the igniter button by turning it left to reveal the battery.

First verify that the rotisserie burner can be lit manually. Take a BBQ lighter or long stick match and then put the flame right at the base of the burner where the electrode is and then slowly turn on the burner valve. It should light within four seconds. If it does not then shut the burner off and check for any restrictions in the gas line for the burner.

If it does light with a match then the spark electrode could be dirty, out of position or simply the wire for the ignition system is loose. Press the igniter button and watch the electrode for a good bright spark at the burner. If you do not see any spark you can verify that the igniter wire has not come loose and also gently adjust the position of the electrode end a little bit closer to the burner using a pair of needle nose pliers(It should not be touching the burner). It does not need to touch the burner but have a really small gap.You can use a small wire brush to gently clean the electrode of any debris that might be causing a weak or no spark

If you are unable to remedy the non-spark issue all is not lost. You can still use the manual lighting procedure I described to light the burner. And remember to be careful when trying these procedures. I do not want you to get injured from delayed gas ignition. Be careful and have a safe holiday.

I have a charbroil commercial gas grill that won't ignite. I have a full tank of propane.....


Hello, here is my check list for your most common gas grill lighting problems:

1) Check your tank. Is it empty or nearly empty? The tare weight (T.W.) of your cylinder is stamped on the collar. This is the weight of your empty cylinder, usually around 18 lbs. Weigh it on your bathroom scale2_bing.gif. Propane weighs 4.25 lbs/gal. If it weighs around 20 lbs or less - Refill it. If not, go to #2.

2) Make sure you didn't turn the gas tank valve on too fast. Some gas hoses have a built-in excess flow valve that stops the flow of gas to a trickle if opened too fast. Close the tank valve, disconnect it and reconnect it. Turn the tank valve back on very slowly and then try lighting it again. Make sure all your grill gas knobs are turned to off when you turn on the tank valve and that you only light 1 burner at a time. If it doesn't help, go to #3.

3) Is the igniter sparking? Some are battery2_bing.gif powered-check the battery or replace it. If you have a standard push button piezzo igniter or a rotary style2_bing.gif igniter, check for spark. Can you hear or see the spark? It's hard to see the spark in bright daylight. It's easier to view the spark at dusk or dawn. It should spark an "arc" at the burner. If not, adjust it if necessary. The igniter wire may have a short, causing the spark to arc somewhere else along the wire and not at the burner. Replace igniter wire. It's also possible the igniter tip where it sparks has a cracked or broken porcelain portion of the igniter, causing the spark to not arc at the tip where it's supposed to. Replace the igniter piece. If not, go to #4.

4) You may have a rusted, clogged or damaged burner or venturi tube. With a flashlight, check for spider webs, wasp nests or dirt (mud) dauber nests in the opening of the venturi tube where it connects at each gas valve orifice. Clean it out manually or blow it out with air compressor. Make sure the air adjustment opening (on the end of the burner's venturi tube) has not been changed. If it's closed too much, it will be difficult to light and cause lazy yellow flames. If it's not clogged, the burner may just be old and rusted and the burner holes are not allowing very much gas through anymore. It's also possible the burner has rusted so bad, the burner holes have been enlarged, it is falling apart or has cracks along the burner seams. If so, replace the burner(s) immediately. It is unsafe to use. Your local propane co can usually order the parts you need and some will even do the work, if you are uncomfortable doing it yourself. Bring with you the Make, Model and Serial number of the grill, so they can order the correct parts for your specific grill. Also specify whether it's natural gas2_bing.gif or propane.

5) If none of these resolve the issues you are having, it is also possible you have a faulty or defective regulator, which may mean replacement. If the pressure still seems too low and none of the above has helped, and you have a silver/gray regulator; many have an adjustment screw on the top center of the diaphragm. Remove the outer cap and turn the inside screw clockwise in 1/4 turns to increase the pressure until the desired flame size is accomplished. Flames should be as blue as possible, but will burn orange if there is food or drippings on it. Yellow flames are not good, and will soot up everything and not cook as hot as blue flames do. Yellow flames could mean you do not have the right air shutter adjustment, clogged burners, or possibly defective burners, as mentioned above in #4.

6) Also make sure you have the hose connection tightened snugly to the propane tank valve to ensure the inner valve seat is fully depressed allowing gas to exit fully without any restriction. The black plastic female fitting should be hand tightened only. Older versions that use a left-hand male brass POL valve, requires a 7/8 open end wrench or adjustable wrench to tighten.

Hope this helps! Good luck in your trouble shooting! Douglas

The gas is coming through, but does not light.


I have the same grill,and sometimes the same problem.First,with the gas off or completely disconnected,remove the grill grates and the flavor bars from the grill.Now you can see the heating element.A small wire brush will do the trick.Gently clean all the little holes in the element where the gas comes out.Then,with compressed air or even canned air(like what you use to clean a computer with)blow out the holes you just cleaned.Reassemble the grill and light.Should work fine after that.

Lighting Problem/2 year-Old Ducane Grill


Do you have enough gas pressure coming out of the regulator and gas valve? You'll need a pressure guage for this.

If yes, try taking out the burners and cleaning them with a wire brush, especially the flame spreading sections.
