2 Contro Board Troubeshooting Entering Service Diagnostics Mode To Enter Service Diagnostics Mode NOTE: Ensure that the refrigerator is not in a ockout mode prior to entering Service Diagnostics. Lockout modes incude: Showroom Mode, Cooing Off, and Sabbath Mode. 1. Press both FREEZER and OPTIONS keys simutaneousy for 3 seconds. 2. Reease both keys when you hear an audibe chime. The dispay wi show a 01 to indicate that the contro is at Step 01 of the diagnostics routine. Dispay upon entering Service Diagnostics Mode Exiting Service Diagnostics Mode To Exit Service Diagnostics Mode The preferred method of exiting Service Diagnostics Mode is to remove the grie of the unit and turn the power switch to the Off position for a minimum of 3 seconds. After 3 seconds, turn the switch back to the On position to start the unit again. If removing the grie is not feasibe, the aternative method is to press the ocation where Freezer and Options were ocated on the dispay for a minimum duration of 3 seconds. NOTES: This method may be difficut for some, as the ocations of these icons wi not be it. Waiting for the 20 minute time-out is advised. Service Diagnostics Mode wi time-out after 20 minutes. In the event this occurs, repeat steps to enter Service Diagnostics Mode to continue diagnostics steps. The LEDs within the unit automaticay power down after 10 minutes. To reactivate the LEDs, cosing and reopening the doors, or hoding the switches cosed for 5 seconds, wi turn On the LEDs.
