Fridge not cooling on lp

home now. cleaned the stack with compressed air. Blew out burner area too. Cleaned out the fridge of food and defrosted freezer. Started back up on gas 2 hours ago and put it on the "one snowflake" level which is supposed to be the warmest setting. It's down to 50 after 2 hours. turned it to 3 snowflakes and will check again in a couple hours. I feel like maybe something was plugged in the burner assembly because the flame seems bigger and it sounds Louder. When we were camping, I could barely hear the flame but now it's easy to hear even a foot from the camper. So I'm hoping something was clogging the burner assembly and that it's not something intermittent.
