Ammonia Fridges, read an interesting piece a while ago

My Norcold 2118S was working flawlessly. Then 2 months ago, the temps climbed to 60 in the fridge and 28 in the freezer. I set up a visit with a NORCOLD CERTIFIED technician recommended by NORCOLD. The technician stated it was a bad cooling unit. Norcold has since recommended that the technician come back out for minor things before they will send their own technician a cooling unit to install. Each visit is $175 out of my own pocket due to the mobile tech charge. The reason the mobile charge is that high is they are the closest to my at 2 1/2 hours away. Norcold units may be good but their customer service UNDER WARRANTY sucks. I have decided to scrap their crappy fridge and change to a residential. Norcold can go to #$%^!!!

Note that my RV and fridge are under warranty and are only 6 months old.
