IF — Whirlpool Refrigerator "IF" — Unofficial Ice-System Symptom

"IF" is widely reported on Whirlpool refrigerators as an ice-maker fan / ice-system symptom, but it does not appear in Whirlpool's official refrigerator fault-code table, so treat the meaning as unofficial. If you see "IF" with poor ice production, have the ice-maker compartment fan and airflow checked and confirm against your model's service information.
