Our Dometic three-way fridge is now a one-way: propane only. I've checked the fuse, power gets as far as I can reach. Part of the problem is someone siliconed the whole thing into it's compartment--not easy to get at the back of the unit; can't pull it out, easily. No 12V or 120V action.
Anyone want to guess at the most likely failure? Heating element?
Here is what you do. Identify the a/c heating element it will be towards the bottom of the chimney do not confuse it with other potentially present element or sensors of any kind.
When your sure you have it Take the 2 wire end terminals off the element. Take an extension cord and cut the end off. Attatch the corrisponding end terminal connectors that will attatch it to your heating element. hook itto the element and plug it in an outlet.
That is how any r/v tech would test that problem. That bypasses everything electronic and is a simple test that answers questions.
If it works its either power or the board. If it doesnt its the element.
Do not attempt to opporate the fridge in this configuration for any prolonged period of time it will potentially eventually freeze the contents depending on preformance and ambient temps.

Good advice, joecamper, just what I would do, but access is tough. I can't get at the "switch" part. Even if I figure out what's wrong, I'm going to have a very hard time making the repair. Un-siliconing, for starters....
