Norcold fridge quit working on gas all of a sudden

[TMfor4ofus]

Fridge all of a sudden just started getting warmer after a day of working great. I checked the flame in the box and it looks good. Nice blue flame, the box and pipe coming out is hot. The pipe at the top of the heat tube is hot. The coil or whatever the radiator thing is looks good. I checked those things and restarted it no problem nice flame, the dial goes to green just doesn't cool? Were home now and plugged it i and it works on AC. I'm just starting to troubleshoot but dont know much if anything about the fridge. It's always worked great in any mode. Any ideas or places to start based on the symptoms I described??
