I have a DOMETIC RM183 3-WAY fridge in my trailer. It works on 120V A/C but not on propane. I have cleaned out all of the gas lines and can get the flame lit it just doesn't seem to produce enough heat for the refrigeration cycle to work. How do I clean the chimney/flue assembly and where can i get a new regulator/thermostat assembly

I had this same problem and here is the possible solution.

The older fridges used amonia and water for a refrigerant. If it sits for a time the two seperate. Remove your fridge and turn it upside down and back again... let it sit for a bit in both positions. Occasionally turn it on.. either with gas or electric if so equipped. The process of heating and mixing the amonia and water will sometimes do the trick. When you notice its starting to get cold let it run a while.

SOURCE: Dometic RM2193 Works on 120V, but not on gaz.

These fridges require that the control switches be in the correct position for the power source you want to use. If you try to operate the fridge on gas and have the electric 120V-AC switch on, all you'll get is the gas pilot light to stay lit. Also, when running on gas, the electric has to be off.

Here's a link to the manual for your unit. Print a copy and save an electronic one for future use, in case you lose your printout.

Hope having the manual helps you to get the fridge working on all the power sources you need! Best regards!

Hello,Depending on the age of the unit, it could have a compressor going bad on it, as the compressor gets hot the valves may not be seating correctly or may be burning out.
You may have also lost some refrigerant, but I am going to lean more to a bad compressor.
Thanks
