Whirlpool Duet Dryer Problem

According to the service manual an E1 code means an open thermistor or wire harness...
THERMISTOR
Refer to page 4-7 for the procedure for servic-
ing the thermistor.
The thermistor monitors the exhaust temper-
ature and cycles the high-limit thermostat on
and off to maintain the desired temperature.
1. Turn the dryer off but keep the electrical
supply connected.
2. Make sure that the dryer is empty and that
the lint screen is clean.
3. Close the dryer door.
4. Select Heavy Duty, Timed Dry, More Time
or Less Time, End of Cycle Signal (Louder)
and Start.
5. If error codes E1 or E2 flash on the dis-
play after 1 minute and the dryer turns off,
the thermistor, or the wire harness, is ei-
ther shorted or open. Check the wire con-
nections at the thermistor or the machine
control electronics board. If wiring checks
okay, replace the thermistor.
6. If the dryer seems to operate normally, re-
move the exhaust vent and start the dryer.
7. Select the desired temperature cycle to be
tested, and select 20 minutes of Timed Dry
heat using the More Time or Less Time
pushbuttons.
8. Hold a glass bulb thermometer capable of
reading from 32�C to 82�C (90� to 180�F)
in the center of the exhaust outlet. Mea-
sure the exhaust temperatures with the
heater on and off. The correct exhaust tem-
peratures for the various settings are
shown in the following chart.
9. If the exhaust temperature is not within the
specified limits, check the resistance of the
thermistor, as shown in the following chart.
If the resistance is okay, replace the ma-
chine control electronics board.

Checkrate/Likes Same dryer I have. Mine is electric. I've heard of thermistors going bad on these before. I wish my inside drum was still that white. The inside still looks brand new on that one.
