I have a 2015 X17z. The Norcold N512 refrigerator is not cooling on propane. AC power works perfect. When I switch to propane, it warms up and eventually, the "n" code shows on the panel (manual states "the cooling unit has stopped cooling"). The propane flame looks good (nice and blue) and I've also tried a new regulator on the propane tanks, so the pressure at the tank into the system should be fine. I'm at a loss here. Perhaps it's part of the propane system/tubing on the fridge that is getting restricted so it isn't heating up enough? Even though the flame looks good, maybe it's actually not strong enough? I don't have a clue how to adjust it.
Any thoughts or advice would be appreciated. Thanks!
