I'm pretty sure the problem is NOT with the lid, but with the regulator. I got a new regulator a month ago and fired up the g2gice and cooked a burger with the lid down for about 20 minutes on a windy day, and the fire did not go out. This was the first cook with the new regulator. My guess is that starting with the 3rd or 4th cook, the fire will start going out. Will know more by next week.
I also spoke with one of their experts (Luke) who said he had not heard of the problem either.
when the fire goes out, propane is still flowing, you can hear it and smell it. Better not light a match or a cigarette... boom. big safety problem.
I think the regulator fails, fire goes out, and then regulator starts working again
