My fridge recently appears to be keeping a temp much colder then it was; I believe this began at or shortly after our home briefly lost power. It is set to 39 F, I'm not sure if this was what it was set at before, but we have food now getting much colder then this (i.e. ice forming).
Could the power outage have faulted something? What's a common failure that would be the cause of this?
It is a Whirpool Fridge from 2013. Model number is WSF26C2EXB01.
