Interesting to read this just before I have to go look at the large residential next door as it is not cooling. I also have had a little experience with the 10CF refrigerators & would not ever rely on one other than as a bar reefer. The ones I have worked on do not use the same controls as the larger reefers and are not what I wold consider to be reliable. Last night another friend was telling me he just replaced his 6 year old large residential which had failed.
I don't do this for a living and have very limited experience but find it laughable when I read stories about the reliability of residentials. The new residentials are not the same critter of the past that lasted for 30 years.
