Component Testing; Top Compartment Thermostat & Freezer/Refrigerator Selector Switch - Gladiator Garage Works Freezerator GAFZ21XXMK Series Service Manual

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

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.

• 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.
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).
