I disagree.  Yes there is some danger because if the flame goes out the gas doesn't.  But the heaters for the boiler run until the inside is cool enough and on a hot day the inside never gets cool enough.  Sorry Brett but these things aren't that complicated, and on my Dometic I can use the thermo-couple to hold the solenoid on, so if the fire goes out so does the gas.

I agree, IF the thermo-couple is still in the circuit, that would cover a gas leak/no flame.

BUT, my concern with a heat source is more related to a failed cooling unit.  A failed cooling unit and continued boiler heating can lead to severe overheating or even a fire.

  if it doesn't and the unit is in solid condition ,, then I might just toss in the Amish cooling unit and see how it goes...
Thanks everyone for the great help!
I've learned much.

I bought a U225 with a known bad refrigerator, but it's a Dometic RM4804 with a compressor cooled ice maker so I get to keep one foot in each world.  I installed this cooling unit in February 2019 with hand tools and the supplied materials.

I've had a replacement cooling unit since 2014.  Seems to still be working great although I'm starting to think about a compressor upgrade.

If you put in a new cooling unit, that's the time to add some fans to the back and inside and a ARP safety unit.

While I had my fridge on the floor installing the jc refrigeration unit I did line the compartment with concrete board and was pleased with the way it "cleaned up" the space. Looked pretty shabby the way FT left it. I also added a heat exaust fan I bought from JC.. The fan is thermostat controlled BUT once it comes on it NEVER shuts off for the duration the fridge is on even in cold weather. I don't care for that because it would shorten fan life plus if boondocking I have the battery draw from the fan. Not a big issue as I am not full time but I would feel better if the fan shut off once the coil temp cooled to the adequate level. Not sure what if anything I did wrong there  and don't know if I will remove the refrigerator to try and remedy it because it's no small chore removing the unit. May remain a wonderment.

Dub,

If the fan is installed up high, you can access it from the roof vent without pulling the refrigerator.

I wired mine to a switch next to the galley light switch so I could decide when it should/should not run (no thermostat).

It"s mounted towards the top of the cooling unit Bret and my hope is I can reach it from the vent. Not sure of the culprit that causes it to run continuous after thermostat kicks it on.. Jc thinks I wired around the thermostat but I don't believe I did .

Before you replace anything do this easy trick to see if the coils are still good.

Access the fridge from the outside vent. Follow the wires back from the heater to the controller. Remove the controller cover and pull the heater wires. Take an extension cord and cut it in half. With the plugin side add some cramp on spades to the bare wires. Plug the spades into the heater wires. The heaters are AC so polarity doesn't matter. Now plug in the cord to 120v and leave plugged in for 24 hours. This just bypasses the controller and heaters are always on. If after 24 hours your fridge isn't cold your coils are shot. If it is cold you probably have a controller problem.

Be sure to monitor temps on the coils with an IR gun.

Ken thanks for the tip ! I will try your method and see what happens after our coming snow . In no hurry as yet and still mulling over what option I might want to pull the trigger on if I have to replace the coil.
You have all been a great help...
Thanks Much!!!
