Tumble Dryer Error Codes

Tumble Dryer
Display	Description	Cause/Corrective Action
AF (flashing)	Bouncing Airflow Switch	Airflow switch opened/closed 5 or more times during cycle. Check airflow switch. Replace if inoperative.
AF (solid)	Airflow Switch Closed When Resuming Cycle	Allow up to 20 seconds for this condition to clear. Check if airflow switch opens at end of cycle. Replace if inoperative.

AF-2	Airflow Switch Failed to Close After Cycle Started	Airflow switch failed to close after cycle started. Check airflow switch. Replace if inoperative.
Airflow Switch Bounces During A Running Cycle	Airflow Switch Bounces During A Running Cycle	If airflow switch is open for at least one second, heat will be turned off and will remain off until switch is observed closed for at least 5 seconds. If there are 5 airflow switch bounces within 5 minutes control will go to Cool Down portion of cycle, display error message and sound audio signal. When Cool Down portion of cycle ends, control will continue displaying error message until power is cycled or BACK keypad is pressed.
Airflow Switch Does Not Close After Cycle Started	Airflow Switch Does Not Close After Cycle Started	If airflow switch does not close within 5 seconds of start/ re-start of a cycle, control will go to Cool Down portion of cycle, display error message and sound audio alarm. Once Cool Down portion of cycle ends, control will continue to display error message until power is cycled to machine or BACK keypad is pressed.
Airflow Switch Sensed Closed While Not In Run Mode	Airflow Switch Sensed Closed While Not In Run Mode	If airflow switch is sensed closed 30 seconds after entering Idle Mode, or End of Cycle Mode, control will display error message until power is cycled or error clears. Cycle will not start and all user inputs will be ignored. If error does clear, control will go back to previous mode of operation.
Alrn	Break-in Alarm Error	Service door or coin vault switches.

Tumble Dryer
Display	Description	Cause/Corrective Action
Auto Ignition Retry (Gas Models Only)	Auto Ignition Retry	If Ignition Control Module (ICM) fails to ignite gas valve ICM will send an ICM Lockout Alarm to the control.If ICM needs to be manually reset, when control receives ICM Lockout Alarm it will display Cycle Stopped Menu with text prompting user to press START/ENTER keypad. If ICM fails to ignite gas on last attempt of auto retry, control will start Cool Down portion of cycle, display heat error message and sound audio signal. When Cool Down portion of cycle ends control will continue to display error message until power is cycled to machine or a user presses BACK keypad.
DIP Switch/Harness Index Mismatch Error	DIP Switch/Harness Index Mismatch Error	On power up control reads Temperature Index Harness value and compares that with the value of switch 1, switch 2 and switch 3 on DIP switch configuration. If the result is an invalid setup control will not enter Idle mode and instead enter Error Mode. Control will ignore all user inputs and display error message. Machine must be powered down and correct temperature index harness must be installed and/or DIP switch configuration must be corrected.

E FnCS	Fan Motor Centrifugal Switch Error	Clean vents on the fan motor. Inspect wires to the fan motor centrifugal switch. If problem persists, replace fan motor.
E Heat	Machine Did Not Reach Expected Temperature	The ignition control has power, but a flame was not sensed after the programmed amount of retries. Be sure that gas is turned on. If problem persists, troubleshoot the ignition circuit. (Igniter, Cable, Ignition Control Module.)
E Ht	Machine Did Not Reach Expected Temperature	Check heating connections, cycle power to machine. NOTE: To avoid error code "E Ht" on steam-heated tumblers, the Auto Ignite Retry (AIg) must be reset from the factory default of 3 to disabled (0).

Tumble Dryer
Display	Description	Cause/Corrective Action
Rotation Sensor Error	Rotation Sensor Error	If machine is equipped, control will constantly monitor input and calculate cylinder’s rpm. If rpm drops to zero while cylinder is supposed to be spinning, control will go to Cool Down portion of cycle. Once Cool Down portion ends, control will continue to display error message until power is cycled to machine or correct keypad is pressed.
SH	Shorted Thermistor Error	Check wiring diagram between control and thermistor. Check thermistor and replace if inoperative. Check control and replace if inoperative.
Shorted Thermistor Error	Shorted Thermistor Error	When control senses temperature greater than 210 + 4 °F during an active cycle, control will enter Cool Down portion of cycle, display error message, and turn on audio signal. Error message will continue until any keypads are pressed, Cool Down cycle has ended, and temperature reading is less than 210 °F. Once all three occur, control will return to Idle Mode.
Stove and Cabinet Limit Errors	Stove and Cabinet Limit Errors	While heat relay is on, if stove temperature or cabinet temperature reaches high temperature for particular limit thermostat, heater will turn off automatically and control will continue cycle with no heat until limit thermostat resets. Once control reaches End of Cycle it will display appropriate error message, and sound audio signal. Control will continue displaying error message until it returns to Idle mode. On models where stove and cabinet limit thermostats need to be manually reset, thermostat(s) must be reset prior to cycling power or control will return back to Error Mode.
UEn	Airflow Switch	Airflow switch is in open position or is faulty.
