Temperature Encoder
The temperature encoder (knob version)
receives switched DC voltage from the main
control board. There are two possible failure
modes - both are open circuits.
An open circuit from the supply side results in
the refrigerator defaulting to midpoint. The
supply side consists of pins 1 and 2.
An open circuit from the return side results in
inconsistent run mode. The return side consists
of pins 3 and 6.
Failure of the fresh-food-only side results in the
fresh food defaulting to midpoint.
Failure of the freezer side results in the freezer
defaulting to midpoint.
