Test 4 Moisture Sensor - Kenmore 796.8002*.900 Service Manual

Test 4
Moisture sensor
Disconnect the NA6 connector
from the main PCB. Measure
the resistance between the
NA6-6 (GN) pin and a chassis
ground screw. Is the resistance
<1 Ω ?
Put a jumper between NA6-2
(OR) and NA6-4 (BL) to create
a circuit connection for the
continuity test in the next step.
Measure the resistance
between the two moisture
sensor bars on the in the lint
filter housing inside the drum.
Is the resistance <1 Ω?
Check all connections and
wires between the NA6
terminal at the main PCB and
the sensor bars. Check the
resistance is 0Ω.
•Measure the resistance of all wires.
Resistance should be < 1 Ω.
•Check all sensor harness connectors for
corrosion, loose/bent pins, broken wires,
etc.
•Check all harness wires between the main
PCB and the sensor for cuts, or broken
wires.
