left the door accidently open overnight. Alarm on. Emptied the freezer and pressed the super button , also set temp to -20C.
24 hours later the AL is still showing on the display panel. The temp taken with my laser is -4C.
How do I get the temperature to return to -18 or -20C?
Have lost the instruction manual bought the freezer new in November 2006
Thankyou.
