I have a Kenmore Elite Upright Freezer -- Model Number 253.26072100. We recently moved and when I plugged in the freezer, the alarm light has been continuously lit and the alarm sound trips about every 8 hours. I have to push the digital button to turn off the alarm. The freezer temperature digital display flashes between 6 and 7 degrees F. How to I reset the alarm where the light will go out and set the freezer temperature?
