SOURCE: Burner won't light

Clean everything up with a wire brush. The tiniest bit of debris in the ignitor area will prevent a spark.

SOURCE: 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

SOURCE: my weber genesis wont stay lit. i can light the

The new style2_bing.gif OPD valves have a small brass ring located in the female fitting on the LP tank. Over time this ring can work loose and then it does not allow the male fitting to fully depress the OPD valve thus reducing your gas flow
Using a small flat bladed screw driver tighten the small brass ring This should solve your problem
IF not you might want to remove the cap (white) on your regulator and try slowly adjusting the regulator, make small adjustments and try the BBQ My Weber if I set the front and back burners to MED I get right at 350 degrees in 60 degree outdoor temps. Adjusting the regulator will take some time to get it right but If it is not your tank it is most likely your regulator out of adjustment

Had trouble lighting weber Q, replaced regulator still will not light with igniter button, had plenty of spark . It will light manually with grill lighter but will have a small back blow of flames. Tired...

Are you using the valve-regulator or a conversion hose to a 20lb cylinder? a gas problem is different from an ignition problem. If an ignition issue the piezo module on that model has to have a good ground connection because cast aluminum will not ground at the electrode. make sure wires are tight and secure. Also check the "gap" at the tip of the electrode and adjust for strong blue spark. Most barbecues need the electrode gap adjusted when first installed. if an older model dirt and grease will interrupt the spark so make sure the tip of the electrode and area around it is clean -- burner and collector.

Rattling noise coming from gas injector. Tendency to flash back towards the gas injector when on full.

check burners are not blocked, also air gas mix could be wrong you should be able to adjust the mix on the burner , and see if burner is not split this can also cause flash back .

Q 220 Burner tube is not initially igniting all the way around and then some ports are going out. New gas tank so plenty of gas

The ports are probably blocked with grease. This happened to me - I removed the burner tube and used a steel bristle brush to clean the holes - the clue is to use the brush from front to back/back to front, not from side to side - side to side just moves the grease from one hole to the next. Worked like a charm, thought I would have to buy new burners.

My grill is a Genesis Silver B. The front burner ignites but the middle and back burner will not. I took off the tubes and can't see where anything is plugged or restricted. I can hear gas through the...

I believe your model Weber has a Cross Over Tube Burner , on the left side of the interior of the grill, just above the middle and back burner. If that's clogged or needs replacing, that's more than likely the culprit. As, it won't carry gas to those two burners. It is easily replaceable, if necessary.

In case you have misplaced your Owners Manual, I have included a link to it. You can download and print it for future reference.
