9.6 Contact / Moisture
Sensor - FFLE3911QW and
FFLG4033QW
WARNING
When replacing the Contact / Moisture sensor, refer
to the code shown on the list of spare parts, related
to the appliance.

9.6.1 General Characteristics

"Moisture Sensor" or "Dryness Control" retards advancing
of the timer. The device uses an Electronic Control Board
in conjunction with the sensor strips inside the drum, which
comes into actual contact with the clothing as it tumbles.
Wiring Diagram - FFLG4033QW
When the contact
is made with wet
clothing, a short circuit
is created between
the two strips allowing
the power to flow to
the Electronic Control Board, which then acts upon that
information either by allowing the timer to advance or by
stopping it.
Moisture Sensor Control counts the number of times this
short circuit occurs over a given period and act upon that
information appropriately. More 'hits' would mean more wet
clothing in the dryer. In such cases, the control may delay in
advancing the timer for a longer period, to allow more time
for them to dry. Less 'hits' would mean fewer or less damp
clothing in the dryer, in which case advancing of the timer
may not be delayed that long.
NOTE
Contact / Moisture Sensor are not applicable for
Electrical Dryer Model FFLE3911QW.
