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

More clearance is not necessarily better. In fact the owners manual for my Norcold unit specifically states to add baffles if needed to keep the rear clearance at 1", no more, no less, especially around the coils. Air needs to move through them and if the space is too large it will not move fast enough to create the convection currents.

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

Here's something I stole from another site...

Just to clarify a few things about the RV absorption refrigerator -

The heat source, meaning the propane flame or the electrical heating element, is used to "elevate" the amonia/water mixture to the top of the cooling unit. There after it is gravity and the PHYSICAL change of state of the chemicals that does the rest of the cooling work.

The air flow across the back of the refrigerator is also gravity controlled - hot air rises and flows out the roof vent. Cooler air is drawn in through the bottom or side vent to replace this rising air. This rising air collects heat from the evaporator fins as it passes by, thus removing heat from the cooling unit.

Any assistance, especially in HOT weather, will help with this heat dissipation. A fan to move the air need not be a large one to effect a higher efficiency. Also, the addition of sheet metal baffles to direct the moving air through the evaporator fins can be very effective.

Use a mirror to look up into the back of the refrigerator compartment. There should be a maximum of one inch clearance between the evaporator coils and the facing wall. If the clearance is more than this then your refrigerator will benefit by the addition of baffles. It may be necessary to remove the refrigerator to install the baffles, but that is not a hard task to do and may result in a very much improved cooling efficiency.

Yes, keeping it packed is very beneficial to the fridge. Those gel packs to the gills in the freezer, and as many of the available sq. inches in the lower box filled. Water jugs are good filler.
It helps maintain more even temps, which I believe helps the fridge work less, and if you should ever have it off line, the goods will keep the temp longer the more stuff is stuffed.

Glad you got the glitches worked out. Cheers!

Those propane fridges seem like a lot of hassle.

Not to mention the risks... do you realize how many recalls have been done for them because they start fires?

I won't have one ever again. They're expensive, temperamental, and dangerous. Of course, that's just my opinion...

I have one. It's not hooked up and I probably won't use it. I like the chest freezer conversion better. I think that is the route I am going to take.

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

Can you post some pics of your current install? I am curious as to how you have it vented. Also, I don't know if you already stated or not, but how old is this fridge and what did you get it out of?

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

Try not to get frustrated with this. These refridgerators are great once you get them up and running. The air intake should come from outside, through a vent in the side of the bus that is at the bottom of the fridge. The second vent at the top of the fridge should also vent to the outside. This will eliminate any problems with air circulation due to pressure differences between the inside and the outside of the bus (especially when in motion). You also don't want to vent the rear of the fridge to the inside of the living space due to the possibility of combustion exhaust getting into your living space (not a big risk, but still a risk). I will try to find a better picture of what I mean.

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

Here's some pics of how mine is installed...

The first pic shows the upper vent. I had to install the baffle to reduce the clearance to the top coils to about 1". The top edge of the baffle is inline with the top of the coil so the air has to go through the entire coil before it can get up and out.

The second pic shows my ugly mug poking through the bottom vent. It shows how big the vents really are.

The third pic shows the vent cover installed on the outside of the bus. I don't have a great pic of the top vent outside, but it is really just an aluminum louvered grill covering a hole.
