WC pressure was at 12 inches, so I turned it down to 11. I will monitor it now and see if I continue to get carbon build up on the flame meter probe.
Thanks.

WC is set at 11.5. Doug
PS, the correct way to check is to connect the Manometer AT the refer and see what the pressure is at the refer when running.

Thank you that was a great article with illustrations on an RV fridge. Illustration looks quite similar to my norcold burner/flu setup. Still getting a buildup on the flame meter probe even after correcting the WC pressure to 11. Next step was to try addressing any blockage in the flue tube. Was unable to get the cap off the flue tube. Ended up rapping on the tube at the top and bottom to try and free up any buildup. Then blew a little compressed air down the top of the flue pipe with the burner vents covered. Really didn't seem to get any residue out of there. When I get to permanent shore power and am running on electric again, I will wrestle with getting that flue tube cap off and figure out how to remove that baffle. Not much clearance in that workspace
as it is down below eye level unfortunately. Will report back on what I found. Thanks. -Ken

Update on norcold refrigerator flame probe vcarbon buildup. I replaced the rubber hose from the regulator to the propane bottle as it had some cracks in it. I removed the baffle from the chimney. It was clean. Water column pressure was checked and set to 11. Flame is blue and not Yellow on burner. Still getting carbon buildup on flame meter probe? When carbon buildup is removed from flame probe then refrigerator cools better.Not sure what else I can check. Cooling unit works very well on electricity. Any recommendations would be appreciated. Thanks, Ken
