EXPLANATION AND RECOMMENDED PROCEDURE
Indicates an ACU problem.
• Replace the ACU.
Verify that the part numbers of the ACU and the User Interface are
correct for the dryer model displaying the fault/error code. Replace
the ACU and/or UI that does not match.
ACU parameter file missing; replace the ACU.
Indicates a stuck button (depressed for over 20 seconds).
This fault code will ONLY appear when in the service diagnostic
mode. See TEST #6: Buttons and Indicators, page 22.
Replace the User Interface.
Replace the User Interface.
Indicates that the exhaust thermistor is open or shorted. If the
temperature drops below 18° F (> 50k ohms), the exhaust
thermistor is open. If the temperature is above 250° F (< 500
ohms), the exhaust thermistor has shorted. May occur if the
P14 connector is not plugged into the ACU. See TEST #4a:
Thermistors, page 18.
Indicates the moisture sensor strip is open or shorted.
This fault code will only appear when in the service diagnostic
mode. See TEST #5: Moisture Sensor, page 21.
Indicates that the inlet thermistor is open or shorted. If the
temperature drops below 18° F (> 245k ohms), the inlet
thermistor is open. If the temperature is above 391° F (< 328
ohms), the inlet thermistor has shorted. See TEST #4a:
Thermistors, page 18.
Indicates no voltage detected at the heater relay.
• Unplug dryer or disconnect power and check that the wires
are plugged into the heater element(s) and the relay(s) on
the ACU.
Indicates no voltage detected at the heater relay.
• Unplug dryer or disconnect power and check that the wires
are plugged into the heater element(s) and the relay(s) on
the ACU.
Indicates low airflow that may affect dryer performance.
• Confirm that airflow system is not blocked; check lint screen,
exhaust duct, exhaust fan.
Indicates low L2 voltage (less than 50 V) is detected at the ACU.
• Check to see if a household fuse has blown or a circuit breaker
has tripped.
• Confirm the power cord is properly installed and plugged
into the power outlet.
• Unplug dryer or disconnect power and check the relay
connections on the ACU.
• Gas Models Only: Unplug dryer or disconnect power and check
the P14 connection on the ACU (harness loopback on pins 4 & 5).
• Unplug dryer or disconnect power.
