The sensor rods consist of two sensors attached
to a plastic housing on the inside of the drum
support.
The sensors are connected to the main control
board. The sensors are spaced approximately
1/2-inch apart, creating an open circuit to the
control.
• When wet clothes tumble across the two
sensors, the clothes create a very low
resistance between the sensors.
• As the clothes become dry, their resistance
value increases.
• Operation of the touch sensors can be
checked by using the service mode test (see
Service Mode Tests
in the
Diagnostics and
Service Information
section of this service
guide).
• Proper leveling of the dryer is vital for
accurate sensor drying. If the front of the
dryer is raised too high, clothes will tumble
toward the rear of the drum, preventing
contact with the sensors. This could produce
a false dryness reading.
Drum/Tub Lamp
The drum lamp assembly consists of a LED that
comes with its own harness attached. It has a
built-in light shield.
Drum Lamp Diagnosing
With an active display and the door open, check
for approximately 5 VDC at the J303 connector
on the main board. If voltage is present, check
for voltage at the inline connector. If voltage is
there, replace the drum lamp assembly.
Drum/Tub Lamp Assembly Removal
1. Remove the control panel, top cover, control
panel front bracket and front panel (see those
sections of this service guide).
2. Disconnect the inline connector for the tub
light from the main harness.
3. Pinch the tabs on the tub light and push to the
inside of the drum.
