Yesterday I worked on a Follet mod# Ref5. The fridge just wasn't keeping temp (range set between 3-8 degrees Celsius). The condenser was clean and I inspected for any trace signs of oil. This machine has 0" needed for side clearances but I could not find out if there is any specific clearance needed for the back side. Basically I took the fridge away from the wall and within a half hour, the temp was right back in its acceptable range. I'm just wondering, am I on the right track.
