This is a Self Defrosting Freezer with an LED information panel on the outside of the door. Recently, when the door is opened the Red LED indicator light turn on and the number 8 is display (normally 4). Also the interior light either turns on, stays off, or blinks. When the door is closed the indicator lights turn off and the display shows 4. What service, if any, is required when this 8 indicator is displayed?
