Need Gas Grill Help...

Well thats usually how it works. We can do the complicated things, but stupid things like grills, changing high light bulbs, and putting gas in cars is why men are useful.

The tank is really new.

How does a burner get clogged and how do you check this?

Obviously I will wait until the grill cools.  Actually, I'll have to wait for daylight.

How did I know the fireman would reply when I said I was playing with fire?

slight hijack... my hubby forgot to turn it off one night and the neighbor came over banging on our door, "Your house is on fire!!"  flames were shooting up and damn near missed the attic, we'd be screwed.   Bless that neighbor. 

yep, it could be clogged with grease.  check the connections and the tubes...

That's what I'm thinking.

Um...where's the control valve?

The funny thing is, I assembled the grill myself...from all it's little pieces, so you'd THINK I'd know the answer to this...but no.

Okay, Max (Lara's hubby) talked me through taking the burners off.  They didn't LOOK clogged up but I banged some rusty buildup off of them (c'mon, the grill hadn't been cleaned in the YEAR I'd been here) and now all three burners light nicely.  So sometime this week I'm going to thoroughly clean the grill and reassemble...

Whew...glad it was simple.  SO weird that it went from FINE one day to all clogged up the next...

Hey Jen,

You might have a stuck high flow regulator.  Here are some instructions from the Weber Gas Grill site an how to reset the high flow regulator.

My LP gas grill won't get hotter than 250 to 300 F, even with all burners on high. Why?

Since 1995, all regulators (the part that attaches to the gas tank to regulate the flow of gas) have included a safety device that restricts the gas flow in the event of a gas leak. But, you can inadvertently activate the safety device without having a gas leak. This typically occurs if you open the LP tank valve rapidly, or if one or more of the burner control knobs is in an open position when opening the LP tank valve. If you do activate the gas regulator safety device, the grill will only reach temperatures between 250 and 300F even with all burners on the high setting. To reset the gas regulator safety device:

Close the LP tank valve.
Turn all burner control knobs to the OFF position.
Disconnect the regulator from the LP tank.
Open the lid of the grill.
Turn burner control knobs to HIGH.
Wait at least 1 minute.
Turn burner control knobs OFF.
Wait at least five minutes if the barbecue has been lit.
Re-connect the regulator to the LP tank.
SLOWLY turn the LP tank valve all the way open.
With the lid open, turn the front burner control knob to the HIGH position (for Summit gas grills, turn on the left burner in the selected Heat Zone).
Ignite the grill by pushing the crossover ignition button several times.
After the front burner is lit, turn the middle burner control knob (if your barbecue has three burners) and then the rear burner control knob to the HIGH position. (For Summit gas grills, turn on the right burner)
Close the barbecue lid.

The barbecue should reach 500 to 550 degrees in 10 - 15 minutes.

To keep the regulator flow valve from tripping again, when you are done grilling always:
Turn all burner control knobs to the OFF position
Turn off the LP tank valve last

This happens to me ALL the time.  And I've got a brand-stankin new spensive grill, not under heavy use, so the grease clog and rot theories are out.  New tank of propane, so that theory is out.  All I can guess is that either something (like condensation) gets in the line, and takes a minute to work itself out once lit, or something weird with the pressure from the tank...in either case... 

I usually end up lighting my grill, letting it burn at lower temp for a minute, turning it off, then re-lighting.  It fires up nicely the 2nd time, full heat.  Dunno why, but that seems to work.

Wow...didn't know the cause, but the solution i was using wasn't far off.  Thanks TG...
