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.

Replace your water filter
A clogged or overdue water filter is a common cause of low water and ice flow on Whirlpool refrigerators — they are meant to be changed about every 6 months. The OEM-style filter that fits most Whirlpool refrigerators is the EDR1RXD1 ($40-50 OEM, $15-25 compatible).
