I have a six year old Duet GEW9200L electric dryer. Even after putting a average load on heavy duty/high, it will not dry completely- it has some dampness.
I checked the vent and it seems to be flowing clear.
I ran the daignostic test for the moisture sensor. The manaul indicates that during diagnostic mode, I should open the door and touch the moisture sensor- the result SHOULD be a Beep and "03"
When I did it, I got a Beep and "9"; when I removed my finger, the display then went to "6E"
Thoughts?

Thanks

Hello. The number is the control program. here is the instructions from the manufacture. It sounds like the blower wheel may be bad or the thermistor. Here is the moisture bar test procedures. TEST #4 Moisture Sensor Test
NOTE: This test is started with the machine
completely assembled.
This test is performed when an automatic cycle
stops too soon, or runs much longer than
expected.
NOTE: Dryer will shut down automatically after
2½ hours.
The following items are part of this system:
– Harness/connection
– Metal sensor strips
– Machine control electronics
1. Enter the Diagnostic Test mode. See
procedure on page 1.
2. Open the dryer door. If a beep tone is heard
and a software revision number is displayed
on the console as soon as the door is
opened, a short circuit exists in the moisture
sensor system.
➔ If this doesn't happen, go to step 3.
➔ Otherwise, go to step 4.
NOTE: Over drying may be caused by a
short circuit in the sensor system.
3. Locate the two metal sensor strips on the
face of the lint screen housing. Bridge these
strips with a wet cloth or finger.
➔ If a beep tone is heard and a software
revision number is displayed on the
console, the sensor passes the test. Go to
step 4.
➔ If not, unplug dryer or disconnect power.
Access the moisture sensor wires by
removing the toe panel (page 7, figure 11)
and disconnecting the sensor wires from
the harness (figure 9). Go to step 8.
4. Unplug dryer or disconnect power.
5. Access the machine control electronics.
Remove the connector P2 from the circuit board. Measure the resistance across
terminals 1 (yellow/red wire) and 2 (black
wire).
➔ If the ohmmeter does not indicate (infinity)
open circuit, go to step 6.
➔ Otherwise, measure the resistance
across between pins 1 and 2 of connector
P2 on the machine control board. If a
resistance less than 1 MΩ is measured
(with analog or digital ohmmeter), inspect
the control board for any debris bridging
these pins. If no debris, replace the
machine control electronics.
6. Access the moisture sensor by removing the
toe panel (see Removing the toe panel, page
7). Disconnect the sensor from the wire
harness. See figure 9. 7. Measure the resistance
across the outermost
contacts of the cable that
includes the two red MOVs.
➔ If a small resistance is measured, replace
this component (Wire Harness, Moisture
Sensor).
➔ Otherwise go to step 8.
8. Measure the resistance across the pins of
the mating connector. If a small resistance is
measured here, replace this harness (Digital
Wire Harness).
9. Measure the resistance
across each of the outermost
contacts and the center
terminal (ground connection).
➔ If a resistance less than infinity is
measured, replace this component
(Wire Harness, Moisture Sensor).
10. If moisture sensor diagnostic test passes,
check the thermistor: Perform TEST #3a
(Thermistor Test), page 4.
➔ If the problem persists after replacing the
moisture sensor and thermistor, replace
the machine control electronics.
