2011 TT with a Norcold refrigerator. Always worked great on both 110v and propane. Now suddenly still works great on electric, but won't cool at all on propane. I did my best to troubleshoot the problem, and ended up replacing the propane regulator and the propane burner, which includes the orifice. I have a nice blue flame, but, no mas, it still doesn't cool on propane, only on 110v. I'm looking for advice as to what might be the problem and/or what to investigate next. Thanks in advance for any tips!

Have you cleaned the stack? You can do a partial cleaning from the bottom with a flairly stiff wire like a metal coat hanger. There is a baffle a few inches up in the stack that makes the heat circulate in the stack. make sure you rattle the baffle!

I did tap many times on the stack to try to get any soot, etc to fall down, but that's all I've done in that regard. So I guess to get further into the stack, I will need to take it apart as much as I in the small area of the refrigerator that is accessible from the back panel. Are you suggesting that I should try cleaning up into the stack, well beyond the small accessible area?

Yes! Sometimes rust and carbon will fall onto the baffle causing a blockage. Only need t get 4-6 inches up into the 3/4 inch pipe to knock it loose.Model of refer would help.

So is the 3/4" pipe you speak of inside that round sheet metal enclosure?

Yes, the 3/4 inch pipe should be directly above the flame.
