Check: Voltage should
be present between
terminals 85 and 86.
If no voltage is
present, check wiring
connections (see
Sec. 7.2), upper
circuit board (see Sec.
4.9), thermostat (see
Sec. 4.2) and circuit board (see
Sec. 4.10).
If voltage is present between 85 and 86, voltage should
be present between terminals 85 and 87. If no voltage is
present, the relay is defective.

NOTE: To do a continuity check, first be sure all power
to the refrigerator is disconnected or off. Second,
remove all wires from the switch assembly, then check
the switch. After the check, be sure the switch assembly
is wired properly per the wiring diagram.
When the switch arm is depressed, there should NOT
be continuity. When the switch arm is not depressed,
there SHOULD BE continuity. If any of these checks are
incorrect, replace the switch.
