Need help identifying RM model fridge
Hi all,
I finally took possession of my 1971 Overlander Intl 27ft this past weekend, after a year of waiting. It was a gift, so I'm not complainin' ;-)
The fridge is not working, and so far I've only been able to determine that it is a Dometic RM model, 2-door, frost-free, made in Sweden.
The plate at the bottom which shows the model/product numbers is very hard to read from dirt and wear. Can anyone advise how I can determine the exact model number, eg, is it derived from the product number?
Thanks!
Barb

Barb,
The model # should be on the bottom right side inside the fridge. I think there is a plate or maybe sticker with the info. At least there is in mine. If you post a photo someone may be able to help out further. Since I have a '72 it maybe the same model as mine. Does it have separate freezer/fridge doors?

Hi Mary,
Thanks for your speedy reply!
There is indeed a plate in the bottom right of the fridge with the model/product/serial numbers, etc. The model section shows the letters, "RM" and then there are some other digits in the model section far to the right. The product number appears to be a long series of numbers (very hard to read, so don't think a photo would help...).
I'm assuming that the model number should be more than just "RM", right?

Here's a link to a replacement chart showing the old models, their dimensions, and lists of what new models will replace them: http://www.dometic.com/71390b03-95e5...405775ef.fodoc

Yes there's more than the RM. Does your model have 2 doors? I will check mine for you.

Mine is RM 75a. The 75a is in the same silver box as the RM but a little further to the right side. Looks kind of like this:
RM __________ 75a

I think we probably have the same one. If you take a photo of yours inside and out, then the outside overall measurements I can verify if mine is the same.

Yay, Mary...that's it! It's the same as yours, RM75a.
Now to figure out whether it's worth getting it fixed, or just buying a replacement. I shudder to think of the work involved in removing the thing... :-o

After the first 6 times, it gets easier... If you get a replacement, get a new one. Your food and your sanity will thank you.

Did you say "6 times"??
Guess I'll have to hire me some muscle to help. Or just buy a bar fridge and procrastinate removing the original fridge!

Barb,
Terry is saying that because he had a really bad string of "fridge follies", where he was taking out and putting in his fridge more times than a sane person could handle within a short period of time. Good thing he's not sane . I can say this because I know him as a personal friend. A friendship where a bit of insanity is required and encouraged.
Back to taking out the fridge....I believe it is usually at least a 2 person job. Terry has super powers so he did it by himself .

I replaced the RM 75 in both my Overlander and Sovereign with an RM 2820. The new ones are really nice and include an inside light.
I would not even think of trying to salvage the original unless it was in pristine condition.
Replacement is not difficult but you must remove the partition to the right of the unit to reveal the hold down plates (one on floor, one on outer wall) to remove the old one.

I first went with a rebuilt cooling unit, then a refurbished used fridge with a rebuilt cooling unit, then three more replacement rebuilt cooling units (because the tubes became clogged inside the cooling unit), and finally a brand-new fridge direct from Airstream. By the time I got done replacing them, it was taking 90 minutes for every removal and re installation. Too bad Nascar doesn't have fridge swapping...
Now you know why I suggested bypassing everything in between, and going with new.
You will have to run a 12 volt power wire to the new fridge, as the RM70+xx series doesn't have a piezoelectric igniter, but a flint wheel for ignition. Other than that, it's not a tough swap.

Hmmm...notes to self: Terry has super powers. Mary knows Terry. Mary thinks Terry is insane. That means Mary is... ...or maybe by association
Since I don't have superpowers (at least not fridge-removing-super-powers), I think I'll learn from Terry's experience and probably go with just swapping it out rather than trying to repair it...

If they did, you would win hands-down
Thanks for the tips...I think I'll be going the swap route!

Thanks, Ron. Based on everyone's feedback on this topic, it looks like a swap out is the way to go.
I figured the partition might have to be removed, so it's good to have that confirmed...
