Door Switch; Moisture Sensor - GE DPVH880EJ Technical Service Manual

4. Remove the single Phillips-head screw and
the drum light receptacle from the drum slide
assembly.

Caution: Upon reassembly, ensure that the door
switch, drum light, and sensor wiring are retained
and routed properly to avoid contact with the drum.

Door Switch

The door switch is fastened to the front panel by 2
locking tabs (1 on each side). When using non-rack
dry cycles, when the dryer door is closed, the switch
will complete the drum motor circuit, allowing dryer
operation. When the door is open, the switch will
open the drum motor circuit, interrupting dryer
operation. Opening the dryer door will also cause
the door switch to close the drum light circuit,
allowing the drum light to be energized.
When using the rack dry cycle, the drum motor
circuit is not energized. The energized blower motor
circuit is not affected by opening or closing the door.
However, when using the rack dry cycle, opening
the door or selecting DRUM LIGHT on the control
panel will energize the rack dry interlock relay and
open the heat circuit.

Moisture Sensor

The moisture-sensing circuit consists of 2 sensor
rods. They are mounted beneath the lint fi lter on the
drum side of the air duct.
Note: The 2 sensor rods in the air duct assembly are
not replaceable. To replace the sensor rods, replace
the air duct assembly. (See
• The sensor rods are connected to the
main control board. The rods are spaced
approximately ½-in. apart, which creates an
open circuit to the control.
• The control board utilizes a low-voltage
capacitor that charges to approximately 5 VDC
when the circuit is open and discharges to less
than 1 VDC when the circuit is shorted.
• When wet clothes tumble across the two
rods, the clothes create a very low resistance
between the rods, which discharges the
capacitor.
• As the clothes become dry, their resistance
value increases and the charge across the
capacitor builds to approximately 5 VDC.
• 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 sensor
rods. This could produce a false dryness reading.
