Received an old mini-fridge, the Sanyo SR1286-1, and it is missing the knob that I believe is used to control temperature. It is on the upper right corner just below the freezer door. Nothing is missing except that knob. If anyone has any information on where I can get one of these parts, that would be very helpful. Also, if anyone has a manual on this mini fridge, that would also be very helpful as I cannot find one online.

Thank you for your help.
