Component Testing; Moisture Sensor - Whirlpool Duet Sport WED8300SW 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
throughout 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.

MOISTURE SENSOR

Refer to page 4-6 for the procedure for ac-
cessing the moisture sensor.
1. Unplug dryer or disconnect power.
2. Turn off gas supply to dryer.

COMPONENT TESTING

Electrical Shock Hazard
• Check all connections before replacing
components, looking for broken or loose
wires, failed terminals, or wires not pressed
into connectors far enough.
• Resistance checks must be made with pow-
er cord unplugged from outlet, and with wir-
ing harness or connectors disconnected.
• Unless stated otherwise, make all resis-
tance checks by disconnecting the compo-
nent connectors either at the terminals, or at
the central control unit.
3. Disconnect the wires from the moisture
sensor.
4. Set the ohmmeter to the R X 1 scale.
5. Touch the ohmmeter test leads to the
sensor connector pins. The meter should
indicate an open circuit (infinite).
6. Bridge the two sensor strips with a wet
cloth. The meter should indicate continuity.
