User Interface Problem (stuck (UI) button) Indicates a stuck button (depressed for over 20 seconds) or UI mismatch. This fault code will ONLY appear when in the service diagnostic mode.. See TEST #6: Buttons and Indicators, page 21. Exhaust Thermistor Indicates that the exhaust thermistor is open. Temperature drops Open below 18° F (> 50k ohms). See TEST #4a: Thermistors, page 17. Exhaust Thermistor Indicates that the exhaust thermistor has shorted. Temperature Shorted above 250° F (< 500 ohms). See TEST #4a: Thermistors, page 17. Inlet Thermistor Open Indicates that the Inlet Thermistor is open. Temperature drops below 18° F (>245k ohms). See TEST #4a: Thermistors, page 17. Inlet Thermistor Shorted Indicates that the Inlet Thermistor is shorted. Temperature above 391° F (< 328 ohms). See TEST #4a: Thermistors, page 17. Inlet and Exhaust Indicates that the Inlet and Exhaust Thermistors are open. Thermistor Open Will occur if the P14 connector is not plugged into the CCU. Moisture Sensor Open Indicates the moisture sensor strip is open. This fault code will only appear when in the service diagnostic mode. S.ee TEST #5: Moisture Sensor, page 20.

Heater Relay or Connector Problem Indicates no voltage detected at the heater relay. This fault code appears ONLY when in the Diagnostic Test Mode. • Unplug dryer or disconnect power and check that the wires are plugged into the heater element(s) and the relay(s) on the CCU. Restricted Air Flow L2 Line Voltage Error Indicates low air flow that may affect dryer performance. • Confirm that airflow system is not blocked, check lint screen, exhaust duct, exhaust fan. Indicates low L2 voltage (less th.an 50 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. • Unplug dryer or disconnect power and check the relay connections on the CCU. • Gas Models Only: Unplug dryer or disconnect power and check the P14 connection on the CCU. (Harness loopback on Pins 4 & 5) Communication between the CCU and UI has not been detected. • Unplug dryer or disconnect power. Communication Error • Check the harness continuity and connections between the CCU UI to CCU and UI. . Communication Error • Check AC and DC supplies. See TEST #1: CCU Power Check, CCU to UI page 11. • Replace the User Interface. • Replace the CCU. DO NOT REMOVE OR DESTROY PAGE 9
