No model #. For electronic / dsi models.
Check your 12volts first. Use a good quality meter, measure across terminals on relay board. Should be greater than 12v, especially if converter is plugged in. Otherwise, erratic operation can result. If voltage good, contact dometic for potential service issues regarding controls wiring. There are 2 models so far off top od my head.

For models that are manual operation.
Your mode switch is on its way out or shaft has started to slip and handle / pointer does not line up with mode properly. Verify handle position, test mode switch. Both of these tests are in the manual.

Try looking on side of the chimney / flue for a rewritable thermal fuse. Will have two wires coming out of it, reset button between them. Press button to reset. If still inop, use a test light and probe across the wires. Clip onto one and probe the other. If the reset button was pressed, and test probe light is on, then you have a bad thermal fuse.

If the thermal fuse resets, take a hard look at why it may have tripped. Operating off level, operating in high temps, blocked ventilation, leaking cooling unit.

Look at the back of your fridge by temoving lower vent / avross panel on outdide. Find the 12v power wires that are likely coming up from floor of compartmentn. They should go to a small terminal block. Make sure they are tight here, on both sides of the block.

Look closely in this area for a fuse holder, probably valued at 25 amps. Check this fuse, replace as necessary. If blown, can be caused by dc heater failing or converter may have surged while running on the shoreline.

Find the AC outlet where fridge is plugged into. See if it has a reset button on it, otherwise check bath and kitxhen outlets for an ourlet that resets the ground fault / earth leakage function. If this is tripped, may have been a surge when operaring on shoreline or generarator or a wiring problem could be present.

You may also have a bad mode switch, especially if frisge is gerting both 12vdc and ac power to it. Its not unusual for propane to continue to be able to operate since that is the preferred mode for most rv / caravan refrigerators.

no ammonia in your fridge http://rvrefrigeratorrepair.com/wp-content/uploads/2016/07/Dometic-Service-AES.pdf and if their was you wouldn't have the tools or way to repair ammonia

If changing thermostat setting doesn’t help, replace thermostat

have it replaced

manual page 3&4 have some info may be other pages also. https://www.altestore.com/static/datafiles/Others/rge400.pdf

thermal coupler is probably bad, the igniter will spark and the gas will be there until you release the igniter button.

there is not one

Yes, I would check your venting. Shut it down and open the access to the back of the fridge. The venting should be apparent and clean of course. Propane has a high water vapor content and contains Carbon Monoxide and should not be burned unvented in small spaces. Good Luck

compressor thermo fuse resets it self

have another tech look at it because he would know would need a tap a line to do pressure readings and add freon --as to reverse polarity that would hurt vehicles or battery operated type equipment as to house hold it would be the the low out put voltage that would damage equipment

We do not have information to help you, but if you will contact an RV dealer, they should be able to help you. Also, type the problem into the "youtube" website. I am right now working on my Dometic with the same problem. My local dealer wants $ 1,600 to fix it. Do some shopping the search engine of your computer. I will be overhauling my fridge myself with the help of YouTube, God bless your efforts.

Check to see if the fan is running that's next to compressor. If not there is the issue.

You may have a peron/freon leak. or it might just be low

At what voltage? 12 v DC or 110 VAC? Have you checked the circuit breaker in the power distribution panel? Is the outlet the 110 volt cord connected to hot? Is the 12 volt converter producing voltage? The only thing that exists between those components is wire. Look for the not so obvious problems like a wire pulled out of the back of the plug the 110 v cord is connected to or inside the power distribution panel for wiring problems.

Usually the heater is not working. They don't hold very much ammonia and usually leak out in storage. We're you using gas or electricity to power it?
