dometic rm8501 help

Looks like my cooling unit assembly is blocked which will condemn the fridge.  otherwise it works perfectly and still cools but not enough.  An annoyance since it is only a 2019 172 with light use.  What are we replacing it with?  Looks like the RM8501 is not really supported anymore.  As an aside, removing the fridge and inspecting the cavity reinforced my opinion that there is no one at the factory that has any skill or desire to do a good job assembling these trailers!  they did manage to insulate 1 of the 3 sides before they ran out of material and just shoved the fridge in at least!  

Thanks- Yes my comment stated "the Factory".  Bad ethos all around from management to line.  There doesn't appear to be any parts or complete refers available anymore...  

thanks Stephen. Ill check it out...

Curious as to the Dometic alternative that StephenH made.  I have neither generator or solar and am curious as to how much battery this unit sucks up.  I have a pair of 12v batteries: a 12+ year old Interstate group size 24, deep cycle and a 3 year old Trojan (85 lbs) T-1275 that gives 165 AH.  We usually boondock so not having the propane option may be a deal breaker when it comes time to replacing this one (our first one lasted 10 years), the current one will be 3 years old next month.

so I think I dodged a bullet...  Since I didn't want to part with the cash to replace the fridge, I set about learning how these things work.  I also put baffles around the rear of the fridge to direct the air to the heat exchange fins since FR does such a piss poor job.  I noticed I couldn't hear the flame at all though it appeared blue and solid.  I removed the gas orifice and cleaned with carb cleaner, reinstall and now the flame is audible.  Frigde now cooling below freezing overnight and 7 degrees celsius in the heat of the day which right now is 29 degrees celsius and the fridge side of the trailer is full sun.  I put an ice cube in the freezer and it is still frozen after 2 days.   Now there is a light coating of frost on the fridge fins where they were not hardly cool before.  we are headed to the desert next week and will see how it goes.
