Nothing is more irritating than a section of your burner not working when you go to grill.
Well – not having any gas in the cannister maybe ranks a little higher in the irritation ladder. 
But if your burner is not fully lighting, you are not going to be able to cook a good steak or burger. Too many hot spots and cold spots.
Sometimes you need to replace the burner but many times a simple cleaning is all that is needed. Clean it and then use a toothpick or something that size (thin but heavy wire is nice) and poke thru each hole in the burner. Take a little time here – it will be worth it.
Yep – I just went thru that and that’s why I decided to drop a post.
Hope you’re having a great holiday week!
