Have you changed your Lava Rocks?
There are no lava rocks. It's a propane grill.
You cant make heat without rocks
gas or not
you need LAVA rocks
the rocks keep the heat
thats why you cant make the temp you want
There are NO rocks with this grill. It always heated to 800 degrees before. Forget it. I will have someone else come over and look at it. Thanks for trying.
