Hi Kevin, why did you replace your old fridge?
After replacing it, have you noticed any difference in the efficiency of the fridge?
I ask because I would like to know if the old ones are as efficient as the new, or if the manufacturers are now using better insulation or whatever.
When I got the trailer 3 years ago, it had the original Dometic RM360 in it. This was a 3 way unit. In really hot weather, it was having a really hard time keeping up. I read all the threads on this forum, I took the fridge out, rolled it on the ground, did all the tricks, I brushed and cleaned out the heating tube, getting rid of the rust on the tube to improve thermal transfer. I put the fridge back in, went on a trip.....a tiny bit better. I then spent $200 by taking it to an RV place for peace of mind. They tested it out and said that the old guy was just holding it's own....on the warmer side of temperature specs for the inside of the box, but still within specs. I did all the nifty tricks, like putting in 2 computer muffin fans to push more air through the radiator. The fridge was just surviving. The one problem going against a fridge in our 1700 boler
, however is the boler
shape. The curved walls do not allow alot of "chimney draft" to draw air from the bottom to the top. This is because the fridge sits above the wheel well in ours, and the top vent is a bit too close to the radiator of the fridge to provide really superior draft.....anyway I am rambling....there is a really good article on proper fridge installation in an RV that shows you all of this......The Boler is the love of our life (after the dog and our daughters, of course), so we decided to invest in a new fridge (an RM2410). We were tired of worrying about the old one.
I even looked into refurbished fridges. A company in Edmonton refurbishes them. They wanted $200 less than I paid for a new one. They replace the ammonia refrigerant, repaint the tubing with ordinary gray paint
The new fridge also gave us an extra cubic foot of space. I could only get it in a 2 way, it is completely manual, which is fine by me. It does not have fancy electronics which could potentially get damaged by the antiquated noisy half-wave rectifier 12V power supply that comes with it.
So I spent the darned spring cutting the cupboards, lowering shelves, moving ouside vents to fit a cubic foot more beer. The new fridge is better. I studied the "new construction". I wouldn't necessarily say it has more insulation. The entire evaporation tubing system looks almost identical to the old one from the RM360. It looks like Dometic put a few more dents in the tubing of the new one to let the ammonia gurgle over the radiator more....maybe to make it more efficient. Bottom line, it was virtually identical in design from the 1970's. I guess good designs never change. So I upgraded for more beer space, more peace of mind, and what appears to be more thermal efficiency....how much more, just a bit more.
Oh, and one more thing.....always to remember that if you buy a different sized fridge than the original, make sure you measure the #$$[at][at]#$# door of your trailer to see if the new one will fit through.
Anyone want to buy a dometic RM360 for real cheap?
