To restore Factory Default settings for the dryer controls, complete the following sequence within one (1) minute.

Step 1 From the Normal Program State, press the Signal (+) button and Time Adjust • to enter the Diagnostic State from the upper or lower dryer keypad.

Step 2 Scroll to the “rS” display on the menu and press Signal (+). The number “004” appears on the display to indicate the number of remaining steps needed to complete the reset sequence.

Step 3 Open and leave open the Lower Dryer Door. The remaining step count decrements to “003” on the display.

Step 4 Press the Time Adjust • and Time Adjust ‚ at the same time. The remaining step count decrements to “002” on the display.

Step 5 Press the Temperature • and Time Adjust ‚ at the same time. The remaining step count decrements to “001” on the display.

Step 6 Close the Lower Dryer Door. The remaining step count decrements to “000” once the Factory Default settings have been restored. The "Power On Reset" sequence then executes.

The remaining step count resets to four and the invalid selection chime sounds when any of the following conditions occur:

∙A reset step is performed out of sequence.

∙An unexpected key combination is entered. The time window expires.

Opening the door to complete the first step marks the beginning of the time window.

This function does not clear either of the upper or lower dryer cycle counters. All other parameters stored in non- volatile memory are returned to the Factory Default values.

The Reset Utility functions the same regardless of which half of the keypad it is initiated from. Once the utility is initiated, all key combinations must be made from the same half of the keypad used to initiate the utility.

The Signal (-)key exits the Reset Utility and returns to the “rS” display on the main menu. Pressing the Signal (-)key any time prior to completion of the reset sequence cancels the sequence and then returns to the main menu.
