This feature is only available on some models.
The high temperature alarm is a function that warns when the temperature of the freezer increases enough to be a problem. The freezer temperature display LED flashes and the alarm sounds.
This alarm sounds in the following cases:
When the appliance is turned on for the first time (therefore the freezer temperature is high).
When the freezer door is open for a long time or opens very frequently.
When the power goes out for a long period of time.
When larger amounts of hot food are placed into the freezer.
Press the Freezer button until the alarm stops ringing.
The LED stops flashing when the freezer compartment sufficiently cools down.
