Running the fridge for 2 days off level?

I can’t pull the rv Home to cool the fridge due to a neighbors waterline issue. At the storage lot my rv is sitting a full bubble off level, I was going to plug it in today and pick up the rv Friday morning to go camping. Can it is for a day and a half off level with the fridge on?

Ammonia fridges are installed because the technology needed to catch up and now it has. The ammonia fridge will become extinct at some point in the near future. Count on that. One less thing to worry about. Fine with me. I have other, more pressing issues.

The main concern with shutting it off it remembering to turn it back on. 🙂

Keep in mind that 3 degrees of slope is 1:19 or 5.24% so many areas that "aren't level" may be just fine. If you want to be really sure, set your level at that angle and then you'll know where the bubble sits for the danger zone for quick checking in the future. To do this, set the level on a board and raise it 1" high, 19" from the end. Remember too that the front to back direction (which is side to side for the way most fridges are in a TT) is 2x that or 1" in 9.5".


Exactly.....or buy into the RV forum banter of how you have to be 100% spot on level.....its your decision!


Of course simple answer is a duty cycle compressor fridge. Don't have to be concerned with a pressurized system. Can operate at peak efficient at up to 30 degrees out of level.

Why my ammonia fridge will be on Flea-Bay next spring, replaced with a duty cycle compressor fridge (winter time project). You'll see a gradual shift to duty cycle (Danfoss/Secop) comnpressor fridges in the future, they are already being installed in many units and... they are less expensive initially. Example, a complete unit (compact, less than 2.0 cubic foot Dometic C series is under 900 bucks, actually less than a rebuilt 'Amish' cooling unit.

No temperature swings and not impacted by high ambient termps either. You set it for say 40 in the box, it stays at 40. What a concept.

Yeah, go figure - ignorance is bliss. :S Despite all the rhetoric from those mocking the need to ensure a gas absorption fridge is reasonably level when sitting still & operating one fact can't be disputed - not one of these pundits will be there ready to ante up for a new replacement fridge when the OP's fridge has failed. :R That in itself should be enough to convince anyone that ensuring level operation each & every time is worth the effort. 🙂

It's hot, fresh, and delicious!

Too many geezers, self appointed moderators, experts, and disappearing posts for me. Enjoy. How many times can the same thing be rehashed over and over?

That's kind of a relief. It's much easier to make sure the trailer is spot on level front to back, which, with most refrigerators means side to side which according to Norcold is the most level sensitive position.

I find it a tad harder to dial in trailer levelness side to side, since we're talking about using either boards or the plastic blocks. Whereas, just a touch of the power tongue jack button will lift or lower the trailer very accurately.

You obviously don't understand what is really the concern and IMO should refrain from commenting on subjects that you are not sure of the accuracy of your information. When traveling the motion keeps the liquid moving and circulating so overheating and lack of liquid circulation is not an issue.

Again for overall best protection I recommend installing an ARP system since otherwise you could be "rolling the dice and hoping".

So what happens if I stop for lunch at a restaurant or truck stop and the lot is sloped, I’ve stopped at a few places with a large sloped lot. Does the fridge immediately start being damaged?


Best practice is to turn it off, but with ARP protection you are basically covered regardless. IMO very cheap insurance for such a finicky and expensive piece of equipment.

Moving helps the coolant circulate and is totally different than parked off level. Also, the vast majority of roads are less than the 5% maximum angle for the fridge.

Side of Fridge to side of Fridge is less critical than back of Fridge to front of Fridge.

Sidecarflip is correct... Look at the back of your fridge or one sitting out in a store and note the direction of the tubes in the back. Front to back is critical as even a minor off level set will trap the liquid{refrigerant} in a low spot and damage will quickly occur. Priced a new frig lately???

Being off side to side is less critical but I agree with the others here who point out that irreversible damage occurs quicker than you think. If parked for more than a couple of minutes just shut it off, as long as you do not open the door you will lose little if any cold. If you forget to turn it back on a few hours with the door closed will not make much difference.

That really depends on which way fridge is installed

On sidewall, rear wall, center wall, angled.

Check out some tests using ARP Real Time Monitoring System
It has actually shutdown fridge during transit while driving up a long steep incline due to boiler temps rising

Accumulative/permanent damage DOES occur from overheating conditions
Overheating is from lack of coolant flow.
Simple thermo dynamics

Perfect 100% spot on level NOT a requirement
Level enough to be comfortable is level enough
Is it time for your medication or mine?

That is what you should do.

20 minutes of off-level fridge operation begins causing damage which is accumulative and permanent


Fore to aft is way more critical than side to side because the cooling unit is thermo siphon. I run mine a full half bubble off side to side with no issues. Fore and aft...always level.

Won't be that way next year with the Danfoss/Secop being installed this winter.
