Kitchen Gas Appliances - Gas range lights - then flames die out

I have a propane GE stove / oven. Recently, out of the blue (well, it may have been coincident with the cold weather, but I'm not sure) I would turn a burner on, it would light, and then the flame would lower (control still in the high position) and go out. Sometimes I can do this over and over again, sometimes I'll have to wait a minute or two until I can get it to light again.

This issue sometimes doesn't come up - after I light it a few times, I might be able to keep it going (like last night for three hours or this morning for eggs), but right now, I am not eating dinner because the oven wouldn't warm up. I played with the broiler on several occasions - once it lit and stayed roaring, but this evening all I could get is a flash of blue flame and then it quickly shrank and died out.

GE came and replaced a part - my wife says he said it was a pressure regulator. It worked great for 2 days, and then poof, same problem again.

I haven't had the gas company out yet - maybe there is an intermittent regulator issue there? Or a leak that has drained the tanks and made them pressure sensitive (running it for 3 hours last night would contradict that theory)?

However it works out, I am starting to get pretty frustrated with this new range.

This is a new install of the propane and appliance, and it worked fine for 3 months. I don't think we could have cooked through two 100lb tanks of propane - we barely use it.

I would call your propane supplier. If you think the problem coincides with the cold weather, then that is likely the problem.

What could be happening is the regulator at the tank likely has some moisture in it which in turn is freezing up. The propane supplier should add some methanol in the tank and possibly replace the regulator.

HankHill -

After reading your reply, I thought to myself, 'Hey, my wife makes eggs in the morning just fine - after the sun has been on the tank for a bit. Same thing when I fired it up in the afternoon'

Anyway, it's below freezing right now, and I checked the stove, and it would light and then go out. Then I came over here, read your post, and had a bright idea.

I soaked some towels in hot water, wrapped them around the regulator (it takes the input from the 2 100 lb tanks) and waited two minutes. Sure enough, all four burners came roaring to life and stayed roaring, no problem

Thanks for your help. Now we'll see if Amerigas listens.
