Webber Q 100

The safety "flow" check valve in the propane tank has tripped.

Open the valve on the propane tank very slowly. This usually prevents the safety valve from tripping.

When mine does this I turn off the grill close the propane tank then reopen it slowly and relight the grill usually works every time.

If that doesn't work turn off grill close propane tank valve disconnet hose from tank. Turn on grill but do not light let the propane bleed off. Close grill valve reconnect hose, open tank valve slowly, open grill valve and light. Should work.

Thank you so much
I will try this tomorrow :)))

I just open the valve on mine when I get to the campground and close it a couple of minutes before the last meal is done. As long as you open it a half hour or so before cooking there should be no problem. There's usually enough propane in the hose after closing the valve to burn for a bit.

Actually, the excessive flow device is located in the Acme fitting/Hose assembly and not the tank.

I wonder if it's because the hose dia. is too small? We've had that problem with our Coleman Roadtrip grill which we run directly off the low pressure line under our TT (removed regulator at the grill) when we had a 20' 1/4" hose. I changed out the hose for a 3/8" hose of the same length and it works better.

I used to notice that when I first started the grill with 2 burners running at full heat, the flame was blue and strong. Then the flames gradually slowed and turned yellow on the tips. I'm no expert on propane but I'm guessing that the 1/4" hose was charged to the full low pressure level at first, then couldn't keep delivering that pressure at max. flow to the grill.

I don't know. At first, I was hoping to run the grill directly from the 5th wheel where the hose runs in the back for a grill that came with the 5th wheel but after reading posts on low pressure and having to take the regulator out, I opted to keep it simple (I guess simple would be to keep using the green canisters) and get a 5 lbs propane tank and the hose that can be used on the webber.
Going to try these ideas now.
Thanks, I'll report back with results

Run mine off a 20lbs cylinder all the time without issue. Certainly sounds like the safety check valve has turned on.

Try another tank, even a 20/30lb and see if it repeats.

Forgot all about this. Seems like I need to review before going camping. Took nearly an hour to cook pork chops! lol
Now I remember, turn tank very slowly. IF that doesn't work, disconnect, let propane run out from the line in the bbq and reconnect. Works!!

when mine does that i turn it off. turn the tank upside down, wait a few seconds turn the valve back on slowly.

What does turning the tank upside down do?
