Switched to Samsung about 2 months ago. Best thing I have done to the coach yet. The hardest part for me was getting the old Norcold out. Took about a day to get the new Samsung in.

Scott,

In our installation, the outside vent was sealed off but the roof vent was left open.
As the condenser fan in the lower rear of the unit generates heat, the heat rises up between the space between the ref and the outside wall and out the roof vent.
Replacement air is drawn in from the coach in the internal space between the lower ref mechanism and it's floor and drawing air thru an opening in the lower front edge below the freezer bin door.
This seems to work fine since there is plenty of air leakage around the coach to keep the flow going.

Charlie - Thanks. I have another question. Our bus is pretty tight as far as air leaks go. We run our exhaust fan in the kitchen to remove fumes. Any concerns about pulling air through the top vent down behind the frig and into the living space? Just curious.

Just wanted to pass along that I've found a recycler for the 1200 cooling units, I think getting them to the right people after we've pulled them out is better then putting them to the landfill.....

Scott,

No, not really, replacement air for the exhaust fan has to find its way into the coach anyway.
When running the exhaust fan it would seem wise to open a window to get good circulation.
Drawing air down from the roof vent and under the coach should be no problem.
Actually the amount of heat generated by this ref is quite small about 120 watts and it has typically around a 50% duty cycle so that should not be a heat load issue.

I had the same experience. I could get a refrigerator for half the price the shop's were quoting but they would not allow me to have the refrigerator drop shipped to their shop.

Then you should find a better shop.
I can get the samsung RF197ACRS for our customers for $1400 or cheaper. The or cheaper is because it's all about the sales, Samsung allows/gives the smaller Appliance dealers the price match ability. So the day I order from my supplier we search the "local"? big box stores (has to be a local competitor that is within your area) and the cheapest price is what will be matched. A copy of the sales add goes with the invoice back to samsung and the dealer gets reimbursed the difference - set mark-up. So I've been buying these refers when the price is best, I can still make a couple bucks, my customer gets a good price & I get the labor to install.
But I always suggest to my customers to go see if you can find a better deal, if so, here's my card, have if delivered here, let me know and I'll see you then.

FYI - extended warranty on the Samsung.....

Note from my supplier....

We have been told by the warranty company, Warrentech, that they will not honor an extended warranty for a product that has been installed into a motor coach or a vessel. The warranty is only valid when installed in a residence.

Just a quick followup to bring this to closure.....

I removed the NDR1292 and replaced the cooling unit using an Amish cooling unit. I am glad I decided to do the job myself. The removal gave me a chance to seriously look at what failed on the old cooling unit and what improvements I could make.

The refrigerator came out rather easy. Although heavy, help was available to remove doors and lay the unit face down on some supports I had fabricated. I quickly discoverd the charred backing material that got too hot under and near the top of the heat stack. The foil coated backing material Dometic uses is nothing but some kind of paper board about the thickness of poster board. It had burned through and about
1-2" into the foam material. That was the first improvement....a better
heat shield.

We removed the old cooling unit and I examined it for the failure point and it was in the goiler area at a failed weld joint. It was very evident from all the yellow staining and power from the leak. Again the unit is 12 years old, so did not expect it to last forever.
Ice maker line was next improvement. Replaced the failed plastic tubing with copper tube and replaced water control valve.

Control board was next. Replaced it with a Dinosaur control board.
No water damage to wood ecking....yet. Insatlled a sheet of laminate material to the wooden deck of the refrigerator cabinet and sealed with chaulking to protect wood from any future leaks.

Used some additional thermal mastic to ensure the cooling line and plates were completely encased for best possible thermal conduction.

Now I have ice again and the wife's ice cream stays hard.
