Cycle Count Test Mode
How to Enter:
Press Temp + Signal Keys for 3 sec during Power On State.
Press Signal for 3 seconds (until beep)
Note: Test mode subject to change without notice
Temperature Test Diagnostic Mode
How to Enter:
Press Adjust Time Up + Down Keys for 3 sec during Power On State.
Press Adjust Time Up and it will display the temperature in Celsius.
Compare vent temp to drum temp to see air flow.
This can be with just power on or dryer running.

Dryer continues to run after cycle completed
Wrinkle Prevent option provides approximately 90 minutes (20 continuous and 70 intermittent) of tumbling in unheated air at the end of the cycle to reduce wrinkling. Press the Wrinkle Prevent button to activate or deactivate this feature. The indicator light above the pad will illuminate when Wrinkle Prevent is selected. Chasing lights appear in the display when the Wrinkle Prevent option is selected. The load is dry, and can be removed at any time during the Wrinkle Prevent cycle.

Testing Electric Heater circuit
Disconnect Blue wire from RY6, turn power on, start dryer read voltage between RY6 Blue wire and CN6 Green wire.
Reading of 120VAC means a proper operating heater circuit. 0VAC means open in circuit.
To test thermostats use ohm meter on lowest scale, any resistance replace component

Testing Main PCB power
output to Heating & Motor circuit.
With motor running in the heating mode, read AC voltage across RY6 and RY5. Any voltage reading means Main PCB is defective.
With motor running in the heating mode, read AC voltage across RY6 and RY5. Any voltage reading means Main PCB is defective.
Testing Motor circuit
With power off read resistance between RY5 Brown and CN7 Blue.
Resistance reading of good motor circuit is about 1.9Ohm. To test thermostat and switch use ohm meter on lowest scale, any resistance replace component.
