Re: Oh no. Dometic RM-2410 fridge flatlines...

Well that sucks. So the fridge has to be perfectly level to work? The world was flat 500 years ago, but that's not the case today. What happens when you are driving in the mountains? Does it turn from fridge to oven?

Re: Oh no. Dometic RM-2410 fridge flatlines...

I have an old dinosaur of a Dometic RM 77, and while it's a solid and dependable fridge, it's pretty finicky. Like you discovered, in order to operate, it's got to be level. That's the downside to absorption- type fridges. They really only work when you're stopped and set up to stay somewhere for awhile.
And for those that may not know- it's never safe to run your fridges off of gas while mobile, and it's not permitted to run/burn gas while filling up at a gas station.

Re: Oh no. Dometic RM-2410 fridge flatlines...

cinci- on the 110/ 12v operation, it can take quite awhile. If it's been setting inoperable for a while, it can take even longer, as the ammonia separates out of solution. An old trick, but which is hard to do if the fridge is mounted, is to tip it from side to side, and then front to back. This can help mix the chemicals.
Also, operation on gas should give you quicker results.

But... if you're hearing rather loud gurgling from it, then that's a bad sign that the cooling unit is shot- very costly to replace. Often times if it's a good fridge, it's cheaper to repair than to replace, like by half in some instances. Also, are you sure it's level front to back, side to side? Good luck.

Re: Oh no. Dometic RM-2410 fridge flatlines...

My RV has a Norcold fridge. The owner's manual says it must be with 3 deg. of level when operating it parked. I asked a local RV dealer about use in transit and they said that the motions of travel compensate for not being level, but that it should be run on DC while underway for safety. Like you I found that it did not work properly unless level. Works fine otherwise. Trying to operate it out of level when parked can actually do costly damage to your fridge.

Re: Oh no. Dometic RM-2410 fridge flatlines...

I have a propane electric fridge, but I think I want to do the chest freezer refer conversion for the Man Cave. Do you think that has to be perfectly level also?

My gas filler is on the opposite end of the vehicle as the propane anyway.
It's just a safety precaution. A wreck or blowout can turn nasty quick if a gas line's ruptured. 8 p.p.m. of propane to air is all that's needed to ignite it. People do it,though, with the main reason being to operate the fridge and gas heat/water heater, but it's not advisable.
Personally, with how my bus handles (it's no cadillac!), I'd rather not take the risk, even with the extra care taken to stabilize the gas lines and all that. I can easily picture a leak developing, and while I have a gas detector, I still would rather not risk it, a main reason being that it's usually just me and my kiddo that are in the thing.
As far as gas stations go- yeah, they kind of take the safety thing to extremes, and while you can put a cigarette out in gasoline, I still won't smoke around the pumps. I'd rather err on the side of caution as well.

crazycal- I don't think it's as critical to a compressor type fridge/freezer, but it's still wise to keep them as level as possible.

Many people run with the reefer on propane...it's fine.

Re: Oh no. Dometic RM-2410 fridge flatlines...

RV refridgerators require specific clearances to ensure proper convection currents to cool the coils. Usually they are 0" clearance on the sides and bottom, 1" clearance on the back. The bottom of the lower vent is usually even with the bottom of the refridgerator, and the top vent is usually above the upper coil assembly either through the wall or out the top. These are very general guidelines and you should try to find out the specs for your specific refridgerator unit, but I do know that if not vented properly, they tend to overheat and not work well.
