8)The Display cycles “n=x:xx”, then “db = On” with a short across the dryness bars or “db = OFF” with an open circuit between the dryness bars.
9)The dryer may be operated as normal with the Read Sensor Display active. The “n=x:xx” portion of the alternating display is the normal time remaining value for the dryer display.
10)The display shows “db = On” when damp clothing makes contact with the sensor bars.

Codes Visible To The Consumer.
The following help codes could appear on the display and may need further investigation.
1)“PF” A power failure occurred during an active or paused cycle. Consumer may push the "Start/Pause" key to resume the interrupted cycle or push the "Off" key to cancel the interrupted cycle and start over with a new cycle.
2)“HP” The thermistor reading is out of range and the dryer cycle is interrupted. Consumer may push the "Off" Key and attempt to run the cycle again. If the condition persists, a service technician should check for a thermistor malfunction or a wiring problem with the thermistor circuit. Service Technician view the Diagnostic Codes and look for code 1 or 2. See Diagnostic Codes chart.
3)“h1” A temperature increase has not been detected on the lower dryer and the dryer advances to Cool- down. Consumer may check for a blocked vent. Service Technician check for heater not functioning, blocked vent, cool air leaking into drum, poor seal between drum and blower, bad connection on igniter sense signal to control board, thermistor malfunction.
4)“h11” A shaker assembly neutral fault has been detected. Shaker relay is
circuit to the shaker assembly.
“Wrinkle Prevent” This is not a fault code but a normal operation signal. During the Wrinkle Prevent phase of the cycle, the output animation shows 1 segment moving around the perimeter of the display. During the continuous tumble portion of Wrinkle Prevent, the animation is constant. After 20 minutes of continuous tumble, the Wrinkle Prevent intermittent phase begins where the dryer tumbles for 10 seconds out of every 5- minute interval. During this phase the display shows the segment moving, and stopping momentarily. This pattern continues until the Wrinkle Prevent phase ends.
