      Your Viking Refrigerator might not be operating due to a couple of reasons: * It may be unplugged. In this case, plug in the unit. * You might not have held the “ON/OFF” button on the display panel long enough. Try pressing and holding the “ON/OFF” button for five seconds.

      If the compressor, condenser fan, internal fan(s), heater, reverse gas solenoid, and alarms are not working but the display is functioning normally, it is likely that Show Room Mode is enabled. To exit Show Room Mode, press and hold the “ON/OFF” button while performing a “Power On Reset” (POR), meaning disconnect and reconnect the power supply to the unit.

    What does it mean if LED light flashing amber and no audible signal heard on Viking Refrigerator?
    • K
      Kristin ParsonsAug 28, 2025
      If the LED light is flashing amber and there is no audible signal, this indicates a Power Failure alarm. You can reset the audible and display alarms by pressing the “ON/OFF” button for approximately one second. Keep in mind that this alarm is normal upon initial installation because the unit was run at the factory to verify quality, and the alarm will resume if the alarm condition still exists.
