Moisture Sensor - Whirlpool LEW0050PQ Job Aid And Service Manual

AIRFLOW
Primary air is introduced into the dryer through
the slots in the air intake cover.
Some air is used to cool the fan and main
motors. The fan motor pulls air from the drum,
and creates a low pressure area. This pulls air
across the heating elements, through the scroll
in the rear panel, and into the drum to dry the
clothes.

DRUM MOTION
The main drive motor is reversible. It starts in
one direction, stops, then reverses direction. It
continues this throughout the drying cycle.

MOISTURE SENSOR

A moisture sensor circuit is created through the
drum baffles and the brushes on the outside of
the drum. As wet clothes pass between the
drum baffle and the stainless steel drum, the
moisture creates a circuit that is read by the
electronic control. The drum baffle contact is
separated from the drum by an insulator, lo-
cated under the contact strip.
