RV Cooling Unit Warehouse

I recall, some time ago, someone asking here on the forum if anyone had used one of these units. Unfortunately, I now have the opportunity to report in. About 6 weeks ago I brought the AS home a couple of weeks before our trip to do cleaning and waxing and such. I turned on the fridge and all was good. Went on a 3 day business trip and upon my return, I had a hot fridge and the dreaded yellow stuff ALL over the outside compartment. A new fridge is $1400!!!!! So I decided to try a new cooling unit.
rvcoolingunit.com is the site.

They claim, (I called and talked to them too) that the Amish have developed, or refined, the chemistry as well as, on my unit, changed the routing of some of the piping. In addition, it appears the paint is better. The OEMs use what looks like primer on the coils, which is a moisture attractant. Both of the units I have had fail in my lifetime have rusted under the chimney insulation. These units have a clear coat. Better? Dunno, and hope to not have that answer for many years!

What I can tell you is this unit works better than any I have ever had! Cooled down to below freezing in 90* heat, in the sun, in 3 hours. I had to move from my normal #4 setting to #3 to keep from freezing items in the fridge. I can load a 6 pack of warm beverage on a hot day and see no appreciable rise in temp. It actually cycles on and off on hot days!
They provide a tube of thermal mastic to promote heat transfer from the fridge to the cooling unit. There was NONE on the OEM install.

Price was $495 and a $100 core credit was promptly paid upon return of the old unit (freight prepaid!).

So far I am impressed.

Sounds great! Is this the cooling core on the back of the Fridge? Did you do the installation? I have researched the replacement process...seems like an easy but time consuming job.

PS....First time I ever heard of an Amish chemist.

Yes I did the work. Replacement is very easy....getting the fridge out of it's cabinet was tricky and getting it back in was a struggle for one person. Very tight clearances. Probably took me about 3 hours.

Allegedly the Amish (some of them) can't use electricity, but can use propane. They have been using gas absorption fridges in their homes for decades, and had the same problems we RVers have. So they began experimenting with the mixture. And there we have it (according to the vendor website) RV Cooling Warehouse is the distributor for the Northern Indiana Amish rebuilders.

Hello dznf0g
Did a search for RV Cooling Unit Warehouse this evening and your comments came up about RV Cooling Unit Warehouse and your purchase of a cooling unit.
Our fridge just went down in our '74 International 31' so I need to do something.
I take it you were pleased with this company?
Any advice you can give would be appreciated
Bob

If you saw no thermal mastic on your removed cooling unit but rather a foil backing, the mastic was under the foil. I don't know why Dometic chooses to do this, but your fridge would NOT have worked at all without the mastic present in some form.

It's been too long now, Lew. I sorta remember a depressed area where the cooling unit fit into up in the freezer part. Can't recall a foil backing or not. But the unit still works very well.
