What Does Error Code ER FF Mean on a Kenmore Refrigerator?

Freezer evaporator fan motor fault.

ER FF indicates the control board isn't reading the freezer evaporator fan turning at its commanded speed. These fans feed back rotation via a Hall/tachometer signal; when actual RPM stays below target or drops to zero, the board flags FF. The most frequent cause is frost from a defrost problem physically stalling the blade, but a failed motor, broken door/cabinet wiring, or a bad fan driver can trigger it too. Unlike ER IF (icemaker fan) or ER RF (refrigerator fan), FF is specific to the freezer evaporator fan.

Models affected: LG-built Kenmore and Kenmore Elite refrigerators, including the 795 Series
What owners report: Owners commonly report ER FF showing up after both compartments start warming, often traced to ice packed around the fan blade. Many find a long unplugged thaw or forced-defrost cycle temporarily clears it, but if frost keeps returning the underlying defrost system usually needs attention.

Frequently Asked Questions

Can I keep using my Kenmore Refrigerator when error ER FF appears? +
It is not advisable. The refrigerator may still power on, but running it while ER FF is active can worsen the fan fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes ER FF on a Kenmore Refrigerator? +
Across reported Kenmore refrigerator repairs, the most frequent is ice buildup blocking the fan blade (45% of cases), failed evaporator fan motor (35%), then broken wiring through the door/cabinet (15%). Check them in that order before replacing any parts.
ER FF keeps coming back after a reset — what should I check next? +
A reset only clears the stored ER FF fault; if it returns, the fan problem is still present. Move on to the physical checks — force defrost / manual thaw, then inspect the fan — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Kenmore Refrigerator error ER FF? +
A DIY repair typically runs $0–$90 in parts, versus $180–$350 for a professional service call, so handling it yourself saves around $180. Expect the work to take roughly 30–60 minutes.
Which Kenmore Refrigerator models show error ER FF? +
ER FF is documented on LG-built Kenmore and Kenmore Elite refrigerators, including the 795 Series. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
