I just received a Sanyo dorm fridge from my son who is no longer using it as he moved to a rental house. While it is a Sanyo, it is a different model than the one your used and when I took the box apart, I found a slightly different mechanism in it. The main different was - no adjustment screw!
Putting it in service at the lowest level closest to the OFF setting produced an internal temperature of 48 degrees.
Since there is no internal screw, anyone have any ideas? Also, it has a small freezer compartment (for ice cubes, I assume) so I am worried about humidity levels as well. Anyone got any ideas - without buying a different controller?
Thanks!
