Dometic RM 3807 Rebuild

Has anyone taken on the challenge of re-building a Three way refrigerator?

I have Dometic RM 3807 with Ice maker in my new to me Classic MH.

I searched for replacements and after much research, I have concluded that either I buy a unit that is about five inches shorter or buy one that is about 1 1/2" taller, (cut cabinets to accomodate)

And......If I desire ice maker, shell out about 1500.00 +/- for the whole thing. Oh, and I would have to replace my beautiful oak door panels with either a black lexan or a fake wood grain panel at additional cost. (I have deluxe real oak panels on current fridge, Royale Designer series.)

Well after much research, I have found manufacturer of re-built cooling units. cost around 500 delivered to door with two year warranty.

I opted to give this a shot for reasons listed above, fit, Door panels, and ice maker. I would gladly pay 1500 if I could buy exact replacement.

So I have my unit removed and taken down to parade rest.

New cooling unit should be here next week.

I am photographing process and will keep you updated but I am wondering if anyone else has gone down this road and what were the results?

Rebuilt reefer cooling units, are a very good deal.

But it depends, as always, who rebuilt the colling unit.

Make sure you use the proper sealant when you change out the unit.

Vulkem or silaflex must not be used.

Thanks for the heads up Andy.
You have known me a while and probably noticed that I do my Homework.

I have talked at length with re-builder and he seems to be stand up kind of guy with attention to detail. No patches and quality work. His company does lots of QA prior to shipping and he offers free two year warranty.

He provides with the shipment a tube of Thermal Mastic and Silicone for installation.

I will say that he also is available 24/7 and has answered every call I have placed, even on Sunday. He answered all of my calls and concerns without any problems.

I feel good about this.

dometic rm 3807 user/ service manual

My refrigerator was working and now and then the check light would come on, and I would turn it off and on and it would work for a while. Now it won't work at all, it sound like it lights then goes off. Is there a service manual or advice of servicing it?


All who wander are not Lost

Be the change you wish to see

don't know about a service manual but when I bought my trailer the fridge gave me a lot of trouble. It would start and cool down and then shut off. If I turned it off and then back on it would start again.
Eventually I determined that the main circuit board(filled with epoxy) was at fault. Seems that they were defective but not recalled.
A transistor would overheat and then the circuit would open and shut down.
After turning off and cooling down everything was good to go again.
Very annoying.
I replaced it with a Dinosaur board and have had no troubles since.
There is a California based web site that gives good info about this.

Here is the website I refered to above.
Check out the page on fault diagnosis.
That Dinosaur board is really good.
I bought mine online from someone in Ohio or thereabouts.
Of course you are in California so I think that I would buy from them if their info is helpful for you.
