Got to my appointment with National Refrigeration in Shipshewana, Indiana, about 6:50 a.m. for my 7 a.m. appointment. They had the new fridge sitting out and they got busy right away. 90 minutes later my brand new Norcold was in and cooling. Cost $1008.00 and that includes everything including removal and disposal of my old Dometic.
Glen told me the RMD 8555 I had in there was a helium system that Dometic tried. It didn't work very well and especially if it got really hot outside, it just couldn't cool well enough. The Norcold 4150 fit right in the same slot.
They are great people to work with and do A/C as well. They replace cooling units on the fridges as well, if you don't need the entire fridge. But mine was dead and that fridge has a bad track record. Glen said they changed out 8 or 9 last year.
Done with buying ice every day! Did it for 2 weeks!
