Any ideas ! (i was wandering if its ‘Sensor Failure’ not allowing the thermometer to read the temp). July 31, 2012 at 10:47 am #378784 adminKeymaster Re: Whirlpool chest freezer SF in display. HI ” Super freeze ” ?,There doesn’t seem to be much info about this one.It does have a electronic module so it may be sensor failure.
