Electrical Shock Hazard

Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

COMPONENT TESTING

Before testing any of the components, perform
the following checks:

• Control failure can be the result of corrosion

on connectors. Therefore, disconnecting and
reconnecting wires will be necessary through-
out test procedures.

• All tests/checks should be made with a VOM

or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.

• Check all connections before replacing com-

ponents, looking for broken or loose wires,
failed  terminals,  or  wires  not  pressed  into
connectors far enough.

• Resistance checks must be made with power

cord unplugged from outlet, and with wiring
harness or connectors disconnected.

TOP COMPARTMENT THERMOSTAT
& FREEZER/REFRIGERATOR
SELECTOR SWITCH

Refer to page 3-2 for the procedure for servic-
ing the top compartment thermostat & freezer/
refrigerator selector switch.

1.

Unplug refrigerator or disconnect power.

2.

Set the ohmmeter to the R x 1 scale.

3.

Disconnect the wires from the thermostat
terminals.

4.

Clip the ohmmeter test leads to the ther-
mostat terminals and turn the knob/baffle.
The meter should switch between conti-
nuity (0 

Ω

) and an open circuit (infinite) at

the trip setting.

Thermostat
Terminals

Selector Switch
      Terminals

Knob/Baffle

5.

Disconnect  the  wires  from  the  freezer/
refrigerator selector switch terminals.

6.

Turn the knob/baffle until the button on the
freezer/refrigerator selector switch is out.

7.

Touch  the  ohmmeter  test  leads  to  the
COM and N.C. selector switch terminals.
The meter should indicate continuity (0 

Ω

).

8.

Turn the knob/baffle until the button on the
freezer/refrigerator  selector  switch  is  in.
The meter should indicate an open circuit
(infinite).

9.

Touch  the  ohmmeter  test  leads  to  the
COM and N.O. selector switch terminals.
With  the  button  pressed  in,  the  meter
should indicate continuity (0 

Ω

).

10. Turn the knob/baffle until the button on the

freezer/refrigerator selector switch is out.
The meter should indicate an open circuit
(infinite).
