Melted control knobs on genesis silver b

[CharliefromLI]

Grabbed a free genesis and the control knobs and igniter wires are all melted. It looks like there was a fire under the control panel. Anyone else ever see this issue? I googled it and saw two posts: one claimed clogged burner(s), the other claims there was a loose screw on the spider screen which caused a leak and flame under control panel.

If anyone has any experience with this issue, let me know.

Yes I had an old Genesis gold do that. That's what led me to get two kettles. Anyway...
 Burner tubes crowded over the years and loosened up just enough to allow the end where they go into the manifold to slip away just enough to allow gas to leak out and catch fire. I lit it up to preheat so I can clean the grates before cooking. About 10 minutes later went out to check on it and two of the three knobs were just a puddle of plastic and on fire.
That grill was pretty old and so I retired it. LOL

I know now that I could have replaced the burner tubes, manifold assembly and knobs and still be using it. But there were other problems with corrosion and rust that it just wasn't worth it to me.

@joetee that makes sense. It looks like the center burner knob was the worst of it. I've done a few burner replacements, I can see how the manifold could slip out or a gap get left. I will take everything apart and search for leaks. Thanks

Your welcome.
If was kind of scary walking out the door and seeing all the fire that close to the gas tank you know.

I can imagine. I might look into an extension hose while I test everything.

Just barely open you gas tank valve just enough to get enough gas out to cook with. This way if there is a problem it won't be too bad hopefully to close it down fast.

Yeah. I will spread soapy water first and see if there is any bubbling anywhere.

Replace the regulator.  I had the same thing.

could you tell if the spider guards were in place?

Ive gotten gassers where they were missing - they usually get brittle and crack by the time the first burner replacement comes around. I use a zip tie sometimes.

So I replaced the regulator as suggested by @glend123 and it did the trick. Thanks!!!
