Dryer not drying all the way

Dryer Repair

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
Doug:confused:

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.
  7. Measure the resistance across the pins of
    the mating connector. If a small resistance is
    measured here, replace this harness (Digital
    Wire Harness).
  8. 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).
  9. 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.
