The Service Mode screen lists four different touch panels; user interface test (membrane switch test), system check, diagnostic codes and exit service mode. Pressing any of the touch screens will activate a different screen dedicated to that function.

The diagnostic codes listed are the last four codes assigned by the dryer.

After 5 minutes of inactivity in Service Mode, the dryer will exit Service Mode and return to the state just prior to Service Mode. If a service test is being run, the control will remain in Service Mode until 5 minutes of inactivity has occurred at the end of this cycle.

This will check the touch screen. The service technician is prompted to “Touch the four corners and center of the touch screen in any order." When each area is pressed, the display will reverse image. If all areas are sensed, the control will display “Touch screen test passed." If any area(s) is not sensed within 5 seconds, the technician will be prompted to “Touch the area(s) not highlighted." If the area can still not be sensed within 5 seconds, the control will display “Touch screen test failed." In either case scenario, the screen will step to the next screen to check the membrane switches.
