The grill we bought last year was recalled not long after we bought it. I didn't know about the recall untile recently when I went looking for a solution to a different problem that we're having with the grill.
I didn't find anything on the Internet about our problem - so here's my contibution. No - not a medical post, but perhaps this will help save someone's eyebrows.
Our problem was that the grill was leaking at the junction of the gas line to the valves. There's a little o-ring. that went bad on two of the three valves in only 1 year.
I looked at the company's (lame) website (the grills are made by Nexgrill, not Charmglow) and found no way to order a replacement part. The poor soul at Home Depot suggested I call the 800 number. The people at the 800 number offered to sell me a new valve assembly and didn't know about any o-ring.
Here's the problem:
You can see where the gas leaked and fire came out. Scary. The valves sit on the gas-line which has a hole in it. Each valve sits in/on the hole .. and the o-ring keeps the gas going to the right place.
I couldn't find anything @ Home Depot that would fit. Real o-rings are too skinny. Finally I found the solution. I bought 1 foot of 1/4" ID, 5/8" OD hose and cutr off tiny pieces of it to make my own o-rings.
Here's one in place of the o-ring:
