Subject: Dometic RM8501 refrigerator, my fix when on gas
Date Posted: 05 Sep 2017 at 8:50pm
We just got back from our trip to Oregon for the Pacific NW Roundup and I noticed on the way up when we ran the refrigerator on gas the refrigerator compartment temperature were higher. I had no problem when I ran the refrigerator on AC. Because everything worked on AC that told me the DC control board and temperature sensor inside the frig were good and the AC heating element were heating the Cooker Mantle so the Absorption System was working. So that meant it was a gas problem. I have suspected my propane regulator was not putting out a normal pressure. Over the last year I have noticed the flame on the stove would show bits of orange or yellow on the flame. Normal is a strong blue flame. I had no way to check the regulator pressure so I decided to by a new one. The one that came with the trailer was a single stage unit. The regulator I brought is a 2 stage for a single tank, JR Products 07-30385 Low Pressure Two-Stage LP Gas Regulator (Fairview GR-9959). You could see a slight difference on the stove and when it was turned to high you could hear a very slight roar, and a good flame, so some improvement. When I tested the frig temp again it was not much better. So I went thru and checked all the voltages to the gas system to make sure they were correct and they were good. That meant the only thing left was the burner assembly. I have never cleaned it in the time I’ve had the trailer, so I watched a Utube video on how to remove it. It was not quite the same as mine but it was close enough. It ended up being quite easy to remove.
There is a recent post by “spydie” describing the removal.

http://www.rpod-owners.com/forum_posts.asp?TID=10609 - Cleaning the Dometic Burner orifice

I did contact Dometic Technical Support to ask them a question about the gas valve and they confirmed that the gas is either on or it’s off. If the Cooker Mantle needs to be heated the flame comes on and once it gets to temperature the flame shuts off. I let the burner assembly soak in engine degreaser for a while them blew it out with CRC Lectra Clean and brushed any surface I could reach. I never removed the jet and I didn’t try to poke anything thru the orifice. The spray cleaner had a pretty good pressure. I put everything back together and checked for leaks, then turned it on. What a difference, the flame was the size it needed to be to heat up the ammonia and vaporize it. The old flame was to small and not putting out enough heat. I ran the refrigerator overnight and this morning when I checked it at 7:30 AM with 4 lights lite up on the temperature setting (5 is max) the outside air temp was 73F (22.7C) and the freezer compartment was 10F (-12.2C) and the main compartment was 36F (2.2C). At 2:30 PM the outside air temp was 91F (32.7C) and the freezer was 14F (-10C) and the main compartment was 38F (3.3C). At 3:30 pm the outside air temp was 93F (33.8C) and the freezer was 16F (-8.8) and the main compartment was 39 F (3.8C). This is what I consider normal for my trailer.

The other thing I have done to the back of the refrigerator is try to improve air flow where the heat plumbing is. I dressed all the wires out of the way so the air rising has good flow. I also filled in the gaps on the sides of the wood deflector with ensolite foam. I them covered the foam and wood as best I could with aluminum foil duct tape. This was all to give the air flow thru the back compartment the smoothest surface and least amount of turbulence. There is not much room to work back there.

Glad you were able to make it run so much better. Maybe I should try cleaning mine. I bought my 2015 pod used and have not been able to get the frig to run on propane. I runs on AC, but not propane.

Adding two computer fans really helps these refrigerators.  I put mine right on top of the cooling fins.  They don't draw much current at all.

I used to post photos with many of the mods I have done. They have changed how photos are posted and you have do it thru another photo sharing site. I do not want to sign up at amy of the third party photo sites so now when I post I just describe what I did. Here is a link to a post I did on the fans that came installed on my Dometic refrigerator in my Pod.

The Fans came with the refrigerator. The refrigerators that are installed in slide outs with the 2 vent panels on the side need the fans to vent the heat to the outside. You can see them if you stick a mirror in and look up or down. Mine is below the condenser tube. Some have a single fan and some like mine has 2 small fans.

So, A great discussion on the fridge. My fridge is also running great on AC but not on propane. Strange thing though, my freezer works great on propane but not the refer part. A local ex RV worker told me that there is  most likely an air bubble in my system and the best way to deal with it is to remove the fridge and turn it upside down for a while and then put it all back together.  Has anyone heard of that before?
Things I have tried: thermoster is working, gas is lighting and burning well. Cycled the fridge twice on AC varying the temperature in the fridge.
What I can't assess due to the placement is the two circulating fans. I assume they are working.
This is a 2012 182 G model.  
Any thoughts?
Thanks
Ron

I have read on the internet about turning the refrigerator over, I have also read just as many post saying driving on a long bumpy twisty road will work just as well. From my testing if your freezer is getting to the correct temperature but the main compartment is too warm I would check your door gasket. I had the opposite problem the main compartment was cold but the freezer was warm. It turned out to be a cracked hinge.
http://www.rpod-owners.com/forum_posts.asp?TID=8031 - Freezer door hinge repair

Absorption refrigerator cool off very slowly and even a small air leak can be a big problem. When I was trying to measure the temp in the freezer and main compartment I had to open and close the doors quickly. This is the reason you turn your refrigerator on 24 hours before leaving because it cools down so slowly. Did you put a thermometer in your freezer compartment to see if it was getting cold enough? If everything is working great on AC but you are having issue with propane them yours may be like mine and the flame may not getting hot enough for the absorption cycle to work correctly. I saw a much better looking flame after I replaced the tank regulator and cleaned the burner assembly. Another item I discovered is my model of refrigerator has an inline ceramic filter located on the gas control valve. I have sent an email to Dometic asking about it. (Dometic Refrigerator Gas Valve Adapter Filter 2923191007)

OK, I have:
Checked door seal- good
Thermoster-good
Trailer is level
Propane tank is full
Cleaned the flue
Cleaned the burner assembly
Have a good flame.
I still cannot get the refer part to get cold when using propane. The freezer works though.
The whole unit works on AC and battery.
Any suggestion?

Propane run time 12 hours. This was after the fridge had been at proper temp on AC.  Outside air temp,was 80f. Elevation is 6000. Did not check actual temp in freezer but water was frozen, refer comp was 52f

All gas appliances have reduced efficiency at high altitude, at sea level air is 20.9% oxygen and at 6000 feet 16.6%. Was your refrigerator compartment full? I live at 25 feet so it does not compare to where you are at. When I was doing my test I had to put items in the main compartment so they would absorb the cold. If it’s empty only the air is cooled and the minute you open the door the temperature will drop. When I did my test I put bowls of water on the shelves and filled the door shelves with sodas. I put a bag of flour in the vegetable storage bin. Even then when I opened the door I would lose 1-2 degrees. In the freezer I put blue ice bags and a ½ pint of water to see how well it would freeze. I'll have to check mine the next time I am at 6000 feet. I have a remote temp sensor I keep in the refrigerator now, that way I can see how cold it is inside without opening the door

Great idea! Do you just switch them on when the outside is at a certain temp?

I switch them on when the outside temp is higher than about 85 or 90F. (above the ambient temp minus 45 degrees F).

Have any installation photos you'd like to share. I'd be very interested in seeing where you mounted the fans, switch and the tap you used for the power.

Have you checked out the fans that came installed from the manufacture on your refrigerator? Mine came with 2 small ones. I have heard some have a single fan. The fans I have move more than enough air when they turn on

AandR,

I've been having intermittent propane problems with my fridge over the last year. I would dissemble the burner, soak it in alcohol, blow it out and it would run fine for a while. Runs great on 120 or 12 volt. It has gotten much more frequent lately so I decided to work upstream. Last week, I had to clean it twice in a week and ended up running on 12 volt for trip home.

I removed the propane line from tank to regulator and from regulator to Pod. I noted quite a bit of oily gunk. Hmmm. I always suspected this might be the cause. I've now ordered a new regulator and will clean the lines as best I can with alcohol.

I'll report back when I install new regulator.

When I cleaned my burner assembly I soaked it in engine degreaser for about 10 minutes, I then used CRC Lectra Clean Electrical Parts Degreaser to blow it off and remove the engine degreaser. The Lectra Clean removes any of the engine degreaser still inside the burner assembly, it also blows out the orifice. I then put in the sun to bake off any thing left on or in it

You can hear the fans when they turn on. They are controlled by a thermal switch so they don't run all the time. They do a very good job of moving air over the condenser tube.

Well, I'm not sure if I can claim victory yet, but today I replaced the stock regulator with a https://www.amazon.com/gp/product/B0024E6TQY/ - Camco regulator  and the results are noticeable.

Last week in Acadia National Park we maintained 5 degrees freezer and 35-37 degrees while on shore power or 12 volt and four lights on the controls. I did give the burner assembly and jet a good soaking w/denatured alcohol and removed and cleaned the regulator-to-pod hose. I reassembled everything, checked for leaks, purged the system and fired up the fridge today.

As I said, not claiming victory yet, but after three hours the freezer is already @ 11 degrees and fridge @ 43. That's a whole lot faster cool down than I had been getting, even after a cleanup. I'm using an https://www.amazon.com/gp/product/B004QJVU78/ - Accurite Wireless Thermometer to monitor. 

I'm just gonna let it run a couple of days on propane and see if it might be fixed.

The one that came on my trailer was a Cavagna Group single regulator and I have seen them on the internet for around $9. It work good for almost 5 years.

I'm down to 4/31. Interesting. When I took the Cavagna Group regulator off, I flushed it with denatured alcohol just out of curiosity. I got a lot of cloudy/somewhat dirty stuff out. My suspicion still remains that I got an overfilled tank of propane that contaminated the system - or some other contaminants.

fred

P.S. I want to add again, my propane fridge problems only arose over the last year. Three years prior - no problem.

Yep, I printed this earlier and will use it to work on it. The regulator replacement will be next if cleaning doesn't work.

I forgot to add to what fwunder said about something coming out of the regulator. When I removed mine, I placed it on my tailgate of my truck and it was there while I installed the new regulator on the trailer. When I was finished and putting stuff away I noticed something had flowed out of the old regulator and coated a small area of the tailgate. My tailgate is black so I don't know the color of what ever it was that flowed out. I had to use alcohol to clean it off the tailgate. So something was in my regulator also.

Thanks!

I'll second the door seal issue. I glued magnets along my door to hold it more firmly against the seal. The latch allowed a lot of movement (in my opinion) and especially during travel where items shift. I've noticed quite an improvement in cool-down time as well as overall colder foods. I put my sodas on the bottom and they're a lot colder when I drink them now, which I love. 

BTW, I started with one magnet-pair, but added two more since the door isn't perfectly flush with the frame and the extra magnets hold it more evenly across the seal. I also made sure and tighten the hinge screws as they had come slightly loose, allowing for more wiggle.

So after reading up on the subject of "oil" contamination in propane lines I am still left puzzled.  I have read completely contradictory explanations and solutions.  

Best I can determine is that SOMETHING ends up in the propane tank.  It SHOULD stay in the tank because all that should be coming out of the tank is vaporized propane.  However, if the tank is contaminated AND relatively full AND is in use while driving, some of that contamination can end up in the lines and regulator as the liquid sloshes around.  It can then foul the regulator and/or the refer burner orifice.  

An open question is... if the burner orifice did get fouled like mine did, can I expect it to recur since whatever contamination got into the lines is still there and migrating towards the burner?  Is it possible that this NEVER happened to our 15 year old pop-up camper because we never ran the fridge while driving (it owuld not stay lit)?  

Fortunately, it is fairly easy to clean the refer burner orifice and the regulator can be checked by observing the stove burner flame height.  

Mostly curious.....

I believe my regulator got fouled and the contamination moved to fridge burner. Once it became apparent, I was frequently cleaning the burner and each time the fridge would return to normal for a while. Then I would have to repeat the process. When I finally decided to replace the regulator, I did find oily goop in the regulator and line from tank to front of pod.

I'm really not sure when or where the contamination came from. Not even sure if any contamination is considered "normal". When I did replace the regulator I flushed the rubber hoses with denatured alcohol. For grins, I flushed the old regulator and noted some pretty cloudy looking stuff coming out. Perhaps I got an overfilled tank somewhere that allowed liquid propane into lines? Perhaps I just got a contaminated tank somewhere? Dunno. I do know that (as of this writing) my fridge seems to be working fine now after a couple of weeks.

I wouldn't be surprised if the problem recurs because I did not flush or replace all lines to fridge, but for now it's definitely better than it was. Just as a point of reference, I have been turning the fridge on (at home) every two or three days (mid 70's ambient) - four lights. Temperature drops quickly and within 4-5 hours freezer is 6-10 degrees and fridge 34-36.

I tried flushing my regulator with denatured alcohol also and like you, got some nasty looking crud out of it. I took the lines loose from the regulator and refrigerator also and used my compressor to blow out the line from the refrigerator end. There was a puddle of some sort of oily looking liquid on my driveway when I looked. Since I get propane from various sources, I do not know where the liquid came from. After reconnecting all lines (and leak testing), I turned the refrigerator on. After it lit, I noticed that the flame sounds stronger although I can't really see much of a difference. I'll see how it goes.

We are planning a short trip to Holly Point campground at Falls Lake next week. I'll be able to see how it performs to a certain extent, but the weather is expected to be cool. I won't be able to tell how it will be in hot weather until next summer.

I recycled the two pancake fans from the old Dometic that I replaced with a Norcold.  We tried it out in some 95+ temps and it worked very well with everything staying nice and cold in the fridge.  I didn't measure the temperature but using the bottled water test, drinking some, it was just as cold on gas as AC.  The Norcold comes with a single fan.  I mounted the two old fans above, pushing the air out the upper vent.  So far, knock on plastic, it's working very nicely.

I am thinking of adding an exhaust fan or two at the upper vent before next summer. I think it will be helpful. It is likely that the screens to deter the mud daubers restrict the airflow enough to exacerbate the problem. If so, the fan(s) should help overcome it.
When we bought the R-Pod, it did have a mud-dauber nest in the flue of the refrigerator. We found that out on the first night out of our first cross-country trip a week after we brought it home in December. The dealer initially said it could have happened in our driveway. I said that was impossible because we only had it a week and that was after a couple of hard freezes and the wasps were not active. They ended up repairing the refrigerator after our first cross-country trip since they had to order parts. They cleared out the nest and replaced the igniter and thermocouple since the flames had shot backward from the burner and had burned the insulation on the wires. After that trip, I put screens on the refrigerator, furnace, and water heater openings. I have not had any further mud-dauber problems.

On the Rpods, the way the louvers are oriented produces a convoluted path for exhaust air and probably impedes passive air circulation.  

I figured that since most of the places we camp have shore power, a small 120VAC fan plugged into the outlet in the refer enclosure should help.  However, I tried several mounting methods for a Whisper Fan (120VAC low velocity / very quiet muffin fan) and discovered that unless I fabricated some sort of soft mount, the "growl" from the fan motor could easily be heard inside the trailer and was rather annoying.  YMMV.  

I wonder if simply directing the flue exhaust outside the enclosure (as opposed to just dumping it inside) would help, especially when running on gas?

I appreciate the suggestions. I have also thought that extending the flue outlet to dump the heat outside would be helpful. I'll have to see what it would take to make it work.

I made a simple bracket out of a left over piece of flat galvanized steel with holes that I had purchased from Home Depot.  I bent the ends to give me a mounting base on the top of the fridge area, attached the pancake fans and wired them up, attached the fan assembly to the top of the space with some 3M mounting tape and coarse threaded screws and away I went.  The fans are quiet and really add to the air circulation.  Total cost $0.  Labor, about 30 minutes including all the wiring work.  The result, a nice cold refer in hot weather with barely audible pancake fans.  

If anyone wants a picture of what I did, PM me and we can make arrangements to send one.

Are the fans as originally installed supposed to run full time or are they on a thermostat?

They are operated with a temperature switch on the heat exchange fins.  I just added two more fans to the existing fan circuit.  Seems to work fine.  The fridge runs nice and cold, even in the +100 temps of Lee's Ferry, AZ.
