Fault/Error Code Chart
The fault codes below may be indicated under various conditions and can be accessed through Service Diagnostic Mode.
CODE DESCRIPTION
EXPLANATION AND RECOMMENDED PROCEDURE
Indicates that a power failure occurred while the dryer was running. Press START to continue the
cycle, or press POWER to clear the display.
Indicates low air flow that may affect dryer performance.
Confirm that airflow system is not blocked. Check lint screen, exhaust duct, exhaust fan.
• Refer to Fault/Error Code “F4E3” below for recommended procedure.
Indicates low L2 voltage (less than 30 V) is detected at the CCU.
• Refer to Fault/Error Code “F4E4” below for recommended procedure.
F1E1
Cycle Control Unit (CCU) Problem
Indicates a CCU problem.
• Verify all connections to and from the CCU.
• See TEST #1: CCU Power Check, page 9.
F2E1
User Interface (UI) Problem (stuck button)
Indicates a stuck button (depressed for over 20 seconds) or UI mismatch. This fault code
will ONLY appear in the service diagnostic mode. See TEST #6: Buttons and Indicators, page 19.
F2E2
User Interface Software Error 1
Appears if UI cannot read EEPROM software from UI.
• Verify all connections between CCU and UI.
• Replace the UI.
F2E3
User Interface Software Error 2
Appears if main control EEPROM is not programmed correctly.
• Replace the UI.
F3E1
Exhaust Thermistor Open
See TEST #4a: Thermistors, page 16.
Indicates that the exhaust thermistor is open. Temperature drops below 18° F (> 50k ohms).
F3E2
Exhaust Thermistor Shorted
Indicates that the exhaust thermistor has shorted. Temperature above 250° F (< 500 ohms).
See TEST #4a: Thermistors, page 16.
F3E3
Inlet Thermistor Open
Indicates that the Inlet Thermistor is open. Temperature drops below 18° F (>245k ohms).
See TEST #4a: Thermistors, page 16.
F3E4
Inlet Thermistor Shorted
Indicates that the Inlet Thermistor is shorted. Temperature above 391° F (< 328 ohms).
See TEST #4a: Thermistors, page 16.
F3E5
Inlet and Exhaust Thermistor Open
Indicates that the Inlet and Exhaust Thermistor are open. Will occur if the P14 connector is not
plugged into the CCU.
F3E6
Moisture Sensor Open
Indicates that the moisture sensor strip is open. This fault code will ONLY appear in the service
diagnostic mode. See TEST #5: Moisture Sensor, page 18.
F3E7
Moisture Sensor Shorted
Indicates that the moisture sensor strip has shorted. This fault code will ONLY appear in the service
diagnostic mode. See TEST #5: Moisture Sensor, page 18.
F4E1
Heater Relay or Connector Problem
Indicates no voltage detected at the heater relay. This fault code will ONLY appear in the service
diagnostic mode.
• Unplug dryer or disconnect power and check that the wires are plugged into the heater element(s)
F4E3
Restricted Air Flow
Indicates low air flow that may affect dryer performance.
• Confirm that airflow system is not blocked, check lint screen, exhaust duct, exhaust fan.
• See TEST #4a: Thermistors, page 16.
F4E4
L2 Line Voltage Error
L2 indicates low L2 voltage (less than 30 V) is detected at the CCU.
• 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.
• Check the relay connections on the CCU.
• Gas Models Only: Check the P14 connection on the CCU. (Harness Loopback on pins 4 & 5)
F6E1
F6E2
Communication Error UI to CCU
Communication Error CCU to UI
Communication between the CCU and UI has not been detected.
• Check the harnres continuity and connections between the CCU and UI.
• Check AC and DC supplies. See TEST #1: CCU Power Check, page 9.
• Replace the User Interface.
• Replace the CCU.
