Sw itch,
icemaker
interlock, no Opens circuit to icemaker w hen freezer door is open to
prevent cycle w hile door is open. Check resistance across terminals w ith:
Sw itch arm depressed Closed
Sw itch arm not depressed Open
Sw itch, light nc Completes circuit to turn on light w hen refrigerator or
freezer door is opened.
Check resistance across terminals w ith
Sw itch arm depressed Open

Sw itch, pow er
DPST Shuts off all pow er to refrigerator w hen sw itch is off
(open). Refrigerator is shipped w ith sw itch on. Check resistance across terminals w ith:
Sw itch off (open) no continuity betw een 1 and 2, 4 and 5
Sw itch on (closed) continuity betw een 1 and 2, 4 and 5
Sw itch,
show room,
SPDT On position completes pow er to lights and display only.
Off position completes circuit for normal operation. Check resistance at test points:
Show room operation - E3, at high voltage board to pin 3 (blue/w hite w ire)
at high voltage w ire harness.
Unit run - E9, at high voltage board to pin 3 (blue/w hite w ire) at high
voltage w ire harness.
