I have an AcuRite 00986 Refrigerator/Freezer Wireless Digital Thermometer and it is showing that the fridge is maintained between 38-42° while the freezer has a much larger range -10° to 5° or so (control set to 3).
If I set the control to 4, I've seen the temperature get down to -19°! (fridge stays okay). With the auto defrost I guess a little more range is normal but should it ever be getting that cold?? I ran diags on the jazz control board and no faults were shown.
I've also had 2 freezer coil ice ups in the past 6 months but deicing and checking drain resolved those.

Am I concerned about nothing?? :)

Thanks!
