Question about Dometic RM2193 Compact Refrigerator With Ice Box

1 Answer

I use a Dometic RM2193 in my pop-up camper. Can anyone tell me what temperature differential I should be able to acheive on 120VAC, propane and 12VDC? On 120VAC I was getting about a 40 degree fairenheit delta (outside temperature 90 degrees, inside temp. 50 degrees). On gas I was only able to achieve about a 20 degree delta. On 12VDC running down the road for 10 hours, the delta was about 10-15 degrees. Any recommendations on how to improve this or is this the limit for this system? Thanks, Phil Johnson, Greenville, SC

Usually from the Bottom of the refrigerator you should have minimum of 43f or colder than ambient. Should work very close to same on both gas and 110, on Dc it may not cool as good. From your description you may have an issue with ventilation. Cold air needs to flow in through the lower vent and out through the upper, if it cant, cooling efficiency is lost. Adding a fan kit can help on hot days. On gas you may have particles that fell down in the burner. Just take the cover off, take the burner screw out and blow down into burner to clean out. compressor or canned air works fine. If cleaning the burner doesn't improve it enough on gas to match electric you have to make sure your regulator on your rv has enough pressure... the fridges require 11 inches of water column.

SOURCE: Our Dometic RM2193 cools on gas but does not work on electric

It could be as simple as a blown fuse at the fridge. Also check to make sure you have turned on the electric switch that allows the fridge to run on AC. Note, you can only operate the fridge on EITHER gas OR electric, but not both sources at the same time, thus, you have to turn off the gas switch before you can run on electric.

When this unit is running on electricity, it has to have the thermostat set for it to run.

Here's a link to the Dometic manual for your model.

Just follow the steps for running on electric and you should be OK.
Hope this helps.

Do you mean it runs OK on gas ?
If so you probably need an element.
If not , you need a new sealed system

SOURCE: no cooling on gas, works great on elect.

I had a similar problem. The flue would get hot and the cooling tubes would get "warm". The refrig would get a LITTLE cool but nothing to be of any help.

I solved it though...it turns out there is a "flue baffle" (twisty little metal thing) that is supposed to hang in the inside of the baffle. It hangs from a screw found on top of the baffle and it is supposed to hang down.

The screw that held mine was corroded and flue baffle had fallen into the baffle and landed on top of the burner.

I ended up fishing the flue baffle out of the top of the baffle with a coat hanger, then rehanging it using a new screw. That solved my problem.

Not sure if this will work for you or not but good luck.

By the way, you can find an owner's manual with a diagram showing the flue, the flue baffle, and the piece of metal holding it here:

http://www.fourwheelcampers.com/DometicRefrigerator.pdf

Look on p.9, figure 9. Item C is the flue baffle and the wire holding it. Item B is the screw that was corroded on mine, and ended up dropping the baffle down to the bottom of the flue.

Below is a link to some generic directions on solving fridge-related problems. I found it to be VERY useful.

Ammonia is what some manufactures use for the refrigerant. You may have a leak in the copper tubing. It may cost more than a new one to have repaired, unless it is under warranty. Sorry.

One of the first things I advise a new owner of any RV is to have the propane system checked by a certified RV technician. I have seen brand new units from factory with propane lines left unattached to appliances, as well as past owners of used units who have decided to try a few things of their own that were extremely dangerous. This unit apparently has sat for approx. 2 yrs, and spiders etc can build nests, bees can build nests that will block ventilation etc, which all can create a situation for a fire or worse. PLEASE, spend the $60, let them clean and inspect the system to give you piece of mind and know that it is safe for your family and friends as well as you. My guess is that it is not a serious problem, and good chance still covered on 3 yr. warranty.

Hi Brian,

You don't want to use a screen that is made to fit. The original part was designed for a specific flame. That being said, colaws rv salvage may have a replacement burner in stock, and you can also try calling up a company that rebuilds cooling units for rv fridges.

Not working on propane


Shut it off, (propane) and used compressed air to try and blow up that stack and clean out any rust that may be in there, as well as check for baffle hooked at top of stack, and hangs down inside the tube.

Dometic fridge inop on A.C. power


There is a fuse at the back of the fridge located near the compressor. You've done quite a bit of checking, so rathe than try to get into stuff, here's some quick info and a link to the manual for your fridge, which should help.

The control switches have to be set a specific way depending on what source is being used and the thermostat turned on when using AC power. Check item #3 Operating Instructions on Page 6 and the control panel switches on Page 9.

Here's the manual for your model, save a copy and print it out and take some time to review the section #3 Operating Instructions on page 6.

http://www.alcovr.com/DATA/MANUEL/DometicRefrigeratorModelsRM2191&RM2193.pdf
Possibly the installation instructions will assist in determining how it was installed in your RV, but usually the installers build around stuff, so you might have to remove some trim in order to get the fridge out, etc.

Hope you find this helpful and will you resolve your issue.

Won't get cold anymore


Good thinking... you need to hire a service technician (a good one!). Too many jackasses think they know these systems. Obviously, there's something wrong with the system.. if so, you need someone who knows what they're working on/with.
