I recently had a Kenmore Pro 79993 refrigerator installed. While my floor i level, the fridge itself appears not to be (the front is a little over 1/4 inch higher than the back). There are leveling legs in the front, but they can only raise it further.
According to the manual page 10 (emphasis mine):
To avoid noise and vibration, the unit must be leveled and installed on a solidly constructed floor. [...] The front should be slightly higher than the rear to aid in door closing.
However, there is no indication of how much higher than front should be. I've done a bit more research with mixed results - some people (including friends) have mentioned that all fridges should be completely level otherwise the hinges might get messed up. Others have said that anywhere between 1/4" - 1/2" difference between front and back is acceptable.
It also seems like the only way to raise the back is with shims, making it seem like the manufacturer did intend for the front to be higher.
I'm just trying to make sure that the fridge has been installed correctly and that it won't be damaged due to being off level.
