Component Function and Testing
April 1998 23 RS1200001 Rev.1
Switch,
icemaker
interlock, no
Opens circuit to icemaker when freezer door is open to
prevent cycle while door is open.
Check resistance across terminals with:
Switch arm depressed Closed
Switch arm not depressed Open
Switch, light nc Completes circuit to turn on light when refrigerator or
freezer door is opened.
Check resistance across terminals with
Switch arm depressed Open
Switch arm not depressed Closed
Switch, power
DPST
Shuts off all power to refrigerator when switch is off
(open). Refrigerator is shipped with switch on.
Check resistance across terminals with:
Switch off (open) no continuity between 1 and 2, 4 and 5
Switch on (closed) continuity between 1 and 2, 4 and 5
Switch,
showroom,
SPDT
On position completes power to lights and display only.
Off position completes circuit for normal operation.
Check resistance at test points:
Showroom operation - E3, at high voltage board to pin 3 (blue/white wire)
at high voltage wire harness.
Unit run - E9, at high voltage board to pin 3 (blue/white wire) at high
voltage wire harness.
Switch, slide Check resistance across terminals
Switch up
Middle terminal to top terminal 0 Ohms
Middle terminal to lower terminal Infinite Ohms
Switch down
Middle terminal to top terminal Infinite Ohms
Middle terminal to lower terminal
Switch, light Completes light circuit when freezer door is open. Check resistance across terminals with:
Switch arm depressed Open
Switch arm not depressed Closed
Thermistor Senses temperatures within refrigerator and freezer
compartments
