My question is off-topic to your original post, but I want to get your thoughts on winterizing that refrigerator/freezer. I know it's early to start thinking of this, but I don't see an easy way to do it. I always use the compressed air method and never have had a problem. Most of the residential refrigerators have a water station that can be used to blow out the 1/4 water line but this one doesn't. I've searched the web and see that some are making "pink ice cubes" but I'd rather not use that since it would take time to work the anti-freeze to the ice maker. (I'm assuming) Have you given this any thought?

BTW, on your issue, 10 deg /hour temp rise sounds excessive, but what is the inside temperature of the trailer? The inside temperature is going to have an effect on the operation of the refrigerator. I know yours is off, but the same applies. This is the reason that refrigerator manufactures void the warranty if used in a non-temperature controlled environment like a garage. Keystone would expect the heat or a/c to be on while the refrigerator is on. I'm assuming that Samsung also assumes that the refrigerator will be in a normal household temperature when in operation. I haven't looked, but I'm sure in the specs there is something that states the operating environment for that model.

Anyway, if you have any ideas on the winterizing, or if anybody else out there has found a quick way, let me know. Thanks.

I thought my dealer told me of a low point drain for the ice maker water line. I looked and did not find one but did find a splice on the water line at the rear of the slide. So I would open it up and let the water drain out to winterize.

There is a "reset" button on the back of the ice maker that dumps the tray and allows more water to come in. It can be used to more rapidly purge water (pink stuff) into the ice maker system.

Your last paragraph starting "BTW" is accurate for a home unit but not applicable for an RV. When I go down the road I do not have power to run the AC so the inside temperature will get up to 90 or 100 and higher in the south west on a hot day. The fridge has to maintain cold with good insulation if no power is applied or as current told by Keystone I have to keep power on it at all times. So the concern of operating in a garage is even worse in an RV.

At this point I can not and will not recommend Commercial Refrigerator for an RV.

Thanks for your reply.
