Side Burner Gas Grill

Gas Grill is just a couple of months and the gas is not flowing well?

Fairly new gas grill. It stopped working one day, but just now stay on. Replaced the old gas bottle with a new, but this did not help. To all gas burners are just a flame coming out of them. The burner rotisserie and side burner does not light at all.

check to make sure hoses are not crimped, and the connections are tight. Not really should listen to much of a hissing sound.
