Question about Refrigerators

1 Answer

Help! In 2006 I purchased a used RV with a dometic model 2408 refrigerator that did not work. After reading up on Absorption refrigerators and repair facilities I had it rebuilt by RV Mobile in Everett, Washington. I re-installed the unit in our RV and turned it on (we use the gas side). I checked it the next day and both the freezer compartment and the refrigerator portion were working well. The next day we arrived for a three week trip and with food for the unit and found it not working. The high voltage transformer was shot. I found and installed a new transformer and once again turned the unit on. We dumped the food and departed. The next day the refrigerator was working well. It worked well during the balance of 2006 and all of 2007. In 2008, on several trips we noticed numerous erratic temperature operations of the refrigerator portion only (the freezer continued to maintain temperature) and on the last week or so of a long trip in October of 2008 the refrigerator portion refused to cool at all but the freezer still remained frozen. After a long hiatus, in July, 2009 I worked with the bottom of the flue, beating on it and vacuuming it. I did get several semi-round rust pieces and much other rust out of the flue. I also removed and cleaned the gas burner as well as the thermocouple and the arc electrode. It still did not allow the refrigerator to operate. We made a 4000 mile trip using bag ice in the refrigerator to provide some semblance of cooling; the refrigerator portion reached a temperature as high as 78 degrees while at the same time the freezer reached as low as 14 degrees. The first of September I removed the refrigerator from its space and working with the top of the flue I removed the flue spiral baffle, used a flue brush on the flue, and then vacuumed and blew out the flue, then replaced the flue spiral baffle. I then returned the refrigerator to its space, fastened it down, reconnected the DC, AC, and gas and re-started the refrigerator. The next day I checked the refrigerator and found the freezer compartment at 14 degrees and the refrigerator compartment at 26 degrees. This made me happy. The following day we again made ready for a trip and when we arrived at the RV with the food for the refrigerator and freezer we found the freezer portion freezing, and once again, the refrigerator portion not working at all. I bought five pounds of dry ice and a cooler and we proceeded with our trip leaving the Dometic operating for the freezer portion. After three days the refrigerator portion began showing signs of life, but never got below 45 ? 50 degrees. I have heard ?urban legends? of removing the refrigerator and turning it upside down or on its side for 12 hours, etc. Each of these sounds to be a bit far-fetched. Is there any truth to these odd stories? Is there any method to get this recently rebuilt refrigerator to provide refrigerator service? And, if so, will it be reliable, or will I have to always worry the refrigerator is going to spoil food at the drop of a hat. We have always kept the unit level. Thanks Gary Engard

The evaporator coil is usually located in the freezer compartment, and there are ducts with dampers that send cool air to the refrigerator. It sounds to me like that may be your problem. It seems that if you move the appliance around a little, (cleaning it and the like), then for a short period you start to get a semblance of cooling. Hope this helps

How do I get a operating and trouble shooting manual for a dometic royale rv refrigerator?

Contact the manufacturer, Absorption refrigeration is an infrequently used alternative to compression refrigeration. Absorption refrigerators use a solution of ammonia and water as refrigerant fluid. A gas flame heats the ammonia and provides the energy that drives the cooling process. These models are generally very simple and have few moving parts. This is a very straightforward process. There are three main principles behind proper operation of an absorption refrigerator. Place the refrigerator on a level surface. Make sure that it is adequately ventilated. Check that the correct heat is being applied in the boiler. As long as there are no leaks, this should be enough for the refrigerator to work properly.

I have a french door Dometic in my 2006 Tiffin RV. It is not working and service tech says it is rusty. Can it be repaired?

An '06? Really? Call an RV service center to see if parts are available. NOT the same place that repair person came from.
You will need a model and serial number B-4 you call them.

I have a 2852 model doesn't seem to be cold enough

RV refrigerators will not always get as cold as your home refrigerator because they operate on a heat absorption principle rather than cold induction. The first thing you need to do is determine the temperature. Place a thermometer in a glass of tap water and set the glass inside the refrigerator and allow it to set for 24 hours without opening the refrigerator. Check it after 24 hours to determine the temp. It should be around 33-38 degrees. Let me know what the results are.

I have a Dometic RM3801 rv fridge that was working fine on 120v and then stopped cooling. All the lights come on but the compressor won't run. It is level and the cooling fins are clean. I checked power at...

your refrigerator is an ammonia absorption system it does not have a compressor only a series of closed pipes and small tanks located behind the styrofoam box so; to operate yout refrigerator you need: a propane flame or, a 12 volt heating coil or an AC transformer to heat the system depending on if you have a 1,2,or, 3 way system.
also; these refrigerators will only work if you are on level ground
so check your fuses, transformer and, or, your gas thermocouple:
the thermocouple is a rod that sits in the burner flame to control the gas valve if you see some yellow dust around the back of the refrigerator you have a leak of the sealed system don't buy a new refrigerator just replace the system and, be sure that you remove the twisted metal riser in the top of the refrigerator vent pipe to use in your new system or, nothing will work the ammonia absorption sealed systems can be bought on ebay etc.
