Component Description Test Procedures
Thermistor Temperature sensing device Check resistance across leads.
Temperature Resistance
77°F 10,000 ohms
36°F 29,500 ohms
0°F 86,300 ohms
Electric
damper control
Damper control balances the air delivery
between refrigerator and freezer
compartments providing temperature
control for refrigerator.
Electrical voltage activates damper
control and door closes restricting flow of
air from freezer compartment to
refrigerator compartment.
Check resistance across terminals.
If no resistance across terminals replace damper
control.
Water
Dispenser
Switch
Single pole, single throw switch
completes circuit for water solenoid when
button is depressed.
Check resistant across terminals.
Water button not depressed:
“NO” terminals are open
Water button depressed:
“NO” terminals are closed
