I am finding it holds temp fine in 12v mode while traveling. At site, I've been switching over the AC. AC works better, as the temps drops on my gauges by a few degrees.

I'm going to save my Lp for boon docking stays and use the 12v when traveling.

I've got a 3-way in my Travato as well. I've only been able to get it to fire on propane once. When on 12V, I can't tell it's doing anything. I was coming to the conclusion it was totally broken, but it seems great on AC.

Will be taking it in for a bunch of other little issues next week, and will have them check it out.

We had a small DOMETIC fridge with 3-way. We used 12vdc for travel and meal stops, propane for overnite. Never a problem. Adding a 12vdc fan in the upper outlet it cooled WAY HUGE BETTER. Rarely made ice cubes before...

Mine has not been a problem. Another member has emailed me with their issue of having a missing burner shield. You may have the same issue, so have your dealer poke around in the service compartment. Here is a pic of what mine looks like inside, for comparison:

The 12 Volt system has a delay built in and the refrigerator starts after the key has been turned on or motor started for a few minutes. It also shuts off when you shut off the key/motor.

The fridge runs off the house 12v system and has nothing to do with position of the ignition switch.

As this diagram shows the ignition switch does control the 12 volt operation of the Refrigerator. This is right out of my Dometic Manual.Click image for larger version

Tdogking,
That is true for your refrigerator. But we have model RML8330 in the Travato and there is no mention of the ignition switch being on for the 12 volt to work.

Gotcha, well a quick look at your manual or a call to the Mfg would answer this question. To me it would seem all 3-way Refers would work this way, but I don't know.

Well, I for one, do not understand why you'd want ANY of the house systems keyed to the ignition. If you have a house battery, separate from the automotive battery, why would you want to turn off systems with the engine? Automatic switching to AC or LP on low voltage, yes please.

It's just a head scratcher to me as to why your refrigerator would work that way, and most people, I think, would not think to expect one to work that way.

It makes perfect sense if the 12v CONTROL circuits are on the house battery and the 12v HEATER circuit is switched by the ignition and powered by the chassis battery and alternator. As the manual stated, the 12v heater uses lots of amps and would quickly deplete the battery. Having it linked to ignition means you don't have to remember to switch it manually.
