"And just to make you happy LM, replacement parts not available ........ "
Why on earth do you think this makes me happy?! I was simply asking a question and the insult was uncalled for. There was none intended on my part so I see no reason one should be hurled against me!
		
		
	 
No insult was intended. It was actually a recognition/compliment that you are the person who 'maintains the rage' in regards to Weber sometimes failing to keep parts available, such as the cookbox for your Summit inside the warranty period. 
When you think about it the Flame Check is a safety device on what was then their top of the range 5000 grill. It is probably made up of standard industry parts. They fail, and unless you then bypass the safety device, the grill does not work. So yes, this is a part I think Weber should keep available.
Your Summit was also a 'Top of the Range' grill, and promoted for it's quality of build. Not doing the base of the firebox in cast or SS (I wonder if they did the Vielux cookbox in all SS?) but enamelled steel led particularly to the panel where the burners enter the cookbox rotting out well before they should have. Should not have happened or at the least replacment parts should be available. I did ponder on this so much that I actually dismantled a Summit cookbox. At first glance they appear to be bolted together- not so- to my surprise they are actually glued together, the bolts I think are to locate the parts while the glue 'sets'. So this i think is the reason why they could not just supply a replacment enamelled steel panel- the glue bond is not easy to get apart, so it would have to be an entire cookbox replacement, as they do with later Summits.
I suspect they ran out of entire cookboxes, and the accounts department stopped any more.
Especially if I had paid full retail price for a 20 year top of the range warranted grill, which has a known flaw, replacment parts should have been available. In SS.
Happy was placed in italics, to signify irony.
LM please check my previous posts in regards to ones you have made. You quite correctly, much to my scepticism, pointed out, that with converting gassers from LP to NG that it is not just swapping the jets, often the valves need to be changed as well. You continue to advise people of this fact, thankfully, as not changing the valves can be quite dangerous.
So, hand on my heart, no insult was intended.Quite the opposite.
LMichaels, long may you 'maintain the rage'.
