Summit S-640 NG Built-In Broken

[JakeSilvey]

Hi all, just bought a house with a Summit S-640 NG Built-in that does not work. The last owner used a stand alone grill which makes me think he couldn’t repair the Weber, and to be fair almost all of these parts have seen better days. The big question… where do I even start? The main gas line going out from the house is turned on but I don’t smell any gas when I turn on the burners.

Sadly those grills will send yo down a dark hole in a NY minute. Me? I'd look into something else. Odds are the firebox is rusted out in front for starters. Odds are there another valve you're missing. As even if you had insect clogs you would smell gas if you turn on a valve.
There are any number of better alternatives though than that generation of Summit

I have to agree with @LMichaels on this one. Very sorry to say, but I think the former owner saw a money pit and decided to let it go.
