I have read various things on this, but will damage result to a Dometic two door refrigerator by being run a few hours not level? I looked this up, and read from everything from a couple minutes non level can cause crystallization of the rust inhibitor to modern absorption refers can be run within 30 degrees without issue.

I RTFM-ed and the manual said something like (and this isn't a direct quote) "if you can comfortably walk in the RV and not worry, it is level enough". That, and no warnings about damage if not level. Just a note about lack of cooling.

This is a head scratcher for me. I know that older models needed three degrees one way, and six the other way, but the modern ones don't seem to have a definite tolerance printed.

I think I killed the cooling unit in my 10-year old 2-door Dometic NDR1292 by parking in a steep driveway. Replaced the cooling unit and all is well now.

But, yes, you could damage your fridge. Dometic does not specify the max incline.

1. It will NOT ruin the CU. But damage will happen. CU's can be ruined by running overnight on an extreme unlevel area. But if it is more than 3 to 5 degrees and for a few hours, you will have some damage. The Ammonia will start a very small crystalization at the upper tube area when running off level. It is very small, but over the years, if you continue those short time unlevel running it will build up and cause a cooling problem. IF you are parking unlevel for ANY given time, just turn the refer OFF while you park for this short time. That will stop any potential problem. Then just turn it back ON when leaving. Doug

Mine runs fine hooked to the truck at night wally docking.And some nights it's even hard to walk straight with the slope in the lot.It will survive a few hours or a night unlevel.


Other half is camping with the angels,Riding alone for now.

Dometic Installation Manuals/Refrigerators Caravan-Motorhomes-RV
INSTRUCTIONS FOR USE


HOW TO START THE REFRIGERATOR Leveling
In the boiler, ammonia vapor is distilled from an ammonia-water mixture and carried to the finned con¬denser, where it liquifies. The liquid flows to the evaporator, where it creates cold by evaporating into a circulating flow of hydrogen gas. If the evaporator coil is not level the liquid readily accumulates, forming pockets which can impair the gas curculation or even block it, in which case, of course, the cooling will stop. When the recreational vehicle is stationary it must be leveled to be comfortable to live in. If the refrigerator is properly installed, the freezer shelf parallel to the floor, the refrigerator will then also perform properly. A bubble level should be placed on the freezer shelf. When the vehicle is in tow, the continuous rolling and pitching movement will not affect the refrigerator as long as the movement passes either side of level, but when the trailer is temporarily parked this sensitivity of the refrigerator should be remembered. So once more, before you start the refrigerator make sure the recreational vehicle is leveled to be comfortable to live in.

ng2951 - you can run them way out of level while driving down the road because the movement and vibration keeps them happy.
A few hours is the same as a few days when it comes to being off level though. According to a big local rebuilder, damage begins after 15 minutes of being out of level. Remember too that the damage is cumulative in that running it a short time off level here and there will add up as the tubing gets blocked. You may not notice the damage until you try to use it in 104 degree heat and find it wont keep up anymore.

I would have to say that they are tolerant of quite a bit of slop otherwise the manufacturer would tell you not to run them on the road.

For comparison, if the refer is installed in the middle of a 20ft camper a 6° tilt would be a vertical difference of 12.6in between the refer and the end of the box. Side to side, 3° amounts to a 4.8in difference between port and starboard sides.

Something tells me you would notice that...
