I ordered our 2014 Lifestyle with the Norcold 4 door fridge. Turned out to be a waste of money. Yanked it out and replaced it with a Samsung residential fridge. Tons more room and cools down to the proper temps in 3 hours or less.
I know this does not help you fix your current issue. RV refrigerators can do the job but seem so fickle. I know many will disagree and say that they are great and do a good job.
However, in every RV I've owned (8) the fridge has been an issue at one point or another. In the very least, cooling consistency an issue.
You can buy 3 or 4 residential fridges for the cost of one new Norcold 4 door unit. I'm done!
If you can't find a satisfactorily resolution for yours, seriously consider gong residential. You have the room. The width of the Samsung and others fit perfectly into the space your Norcold takes up.
Again, sorry I don't have a resolution for the issue at hand but just giving you food for thought. Good luck, Phillip
