    Whirlpool Duet
    I have Whirlpool Duet and it shuts off after one minute, and reads E1. What could I do to fix it?

    E1 code
    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-
    There 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.
