Question about Weber Q Grill
Grill ignites - rather calmly - then back burner slowly ignites. Middle burner does not fully ignite. Gas flow safety regulator trips.
I have already replaced regulator.
Do I need to disassemble the gas line/burners to see if there is some type of blockage?
Shut off the gas at the tank and disconnect everything.
Unscrew the plastic cap on the regulator. Inside is a flat screw top that has a single slot or an X-shaped slot. This is the pressure adjustment. It controls the diaphragm that regulates gas flow.
Note where it's set. Use a Sharpie to mark the adjuster on its edge (place a dot there), and make a corresponding mark on the threads next to it.
Next, use a large screwdriver or a coin to spin the adjuster counterclockwise three or four times. Pay attention to the number of turns. Now, screw it back in (clockwise) the exact same number of turns, stopping at the index mark you made.
Next, turn the adjuster two turns clockwise, followed by two turns counterclockwise. The idea is to end up where it was originally set. This action unsticks the regulator's valve seat. Done.
Put the cap back on, hook it all up, open the tank valve, and make fire.

Bypass valve need reset. All grills made after 1996 have this valve.
