Dometic rm 3800

I have a Dometic Royal RM3800 3-way refrigerator. The refrigerator runs great when connected to electric power and when the generator is running but when in LP mode will light and run for a few hours then shut down. When re-started it will light and operate for a few more hours but the indicator light stays red each time it is re-started and is running. I have cleaned the rust out of the burner tube, cleaned the flume and installed a new volt relay (the old one showed signs of over heating).

SOURCE: Dometic rv fridge runs fine on elec, lights on gas

It is key that all control switches are in the correct position, depending on what power source you are using, gas, electric, etc. If the switches are not in the proper setting, the unit will not operate.

Here's the manual for your fridge that should be printed out for your use and reference (and reading enjoyment). It has all the info needed to operate and troubleshoot it.

Typically, when using any gas appliance with a pilot light, the sensor has to first be hot enough to trigger it to allow the safety gas shutoff to open and allow the gas to flow to the pilot/burner. Follow the instructions and you should be all set.

Yes, you can operate the fridge on propane while driving, instead of running the generator for electric operation. However, you should have a dual tank setup to prevent running out of propane.

Propane tanks with OPD valves aren't holding a true 20 lbs of LP, but rather only hold 17-18 lbs of LP. However, if you're swapping/exchanging your tanks instead of having them refilled, you're only getting 15 lbs of LP in the tanks these days, (check the label at the bottom of the tank to confirm). Hence the reason to have a dual tank setup on your RV to get longer run times.

I thought you might want to have a tech manual for your fridge, so here's a link to the Dometic site, you just need to select yours based on the manufacture date, etc.

Dometic 3way fridge model RM2350R. the fridge works ok, but when i run it on gas the flame lights first time, but the flame indicater does not work,the thermocuple has the right ajustment,is clean,wh


The flame indicator works on very low voltages from electricity generated via the thermocouple. Check the connections and if OK, I would say you are correct in assuming the indicator has failed. These are very sensitive and a bit of a knock can damage them. Try Dometic or Electrolux for a replacement indicator.

Generator was running fine and then the electrical output quit while the engine was running.


Sounds like you did overload the capacity of the generator. What has happened is that the generator was happily running away producing the electricity required for approximately an hour and then an appliance such as an air conditioner, furnace, refrigerator, water heater, or similar large amperage draw fixture decided it was time to kick on for its cycle, or perhaps two or three of them kicked on at the same time, thereby raising the amperage requirement beyond the capability of the generator. All heavy duty appliances run at a given amperage but when they kick on for a cycle they draw almost 50 percent or more amps. Generators rated at 6000 amps or less will not power an entire home or business. When using this size of generator, disable some of your electrical items in the home by unplugging or switching off, and only connect the most important items needed for emergency use. A 3500 watt generator will only run a few lights and a television, plus only one appliance. This means that you could plug in the refrigerator and run it until it has gotten cold enough, then unplug it & connect the furnace or air conditioner or water heater so that they can do there job. Eventually you will be able to rotate through each appliance in turn, and hope the power will return soon. Your generator will likely have blown a capacitor, resistor or some similar repairable item. Some good quality generators will have an overload breaker installed, that trips before doing any damage and all that is needed is to find it and reset it, in order to continue using the generator.

I HAVE DOMETIC DUO-THERM PENGUIN ROOF AIR CONDITIONING ON RV. THE UNIT WILL RUN WHEN PLUGGED INTO ELECTRICITY BUT WHEN GENERATOR POWERED THE AC UNIT KILLS THE GENERATOR ENGINE. WHAT COULD IT BE?


What size & type generator? On start up the AC unit can draw as much as 17-18 amps in some cases, and if your generator is not designed for a quick draw like that it will die.

The refrigerator does not switch to AC power when in the auto mode and the generator is running. It is working fine on LP


If it makes the switch when plugged into AC ok and just not on the generator then there is something coming from the generator interfering with the control. If it will not switch over even on regular AC then the relay board is malfunctioning. You can try tapping on the relay to see if it is stuck. Eric

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.

Dometic Rv Refrigerator cools on gas not electric. Checked electrical connections. It is 30 years old. But has seen great care.


The problem is cavitaion, to fix it, turn it upside down, I know they say never do this but trust me it will work, leave it bottom side up for about an hour then turn it upright for 24hrs, this will relieve the system cavitation and it will run normally when restarted.
