Kenmore Refrigerator Er FF Code: Freezer Fan Troubleshooting
Quick Answer
The Er FF code signals that your freezer fan motor is stuck or defective. Usually, this is caused by ice buildup around the fan blades or a motor that has burnt out after years of use.
Er FF shows up constantly on Kenmore Elite units, and honestly it's one of those codes that can scare you into thinking the fridge is done when sometimes it just needs a good manual defrost. Ignore it and your food safety goes out the window fast because the fridge section won't cool at all. I've shown up to calls where the homeowner waited three days and everything was sitting at 50 degrees. Don't wait on this one.

What Does the Er FF Code Mean?
OK so basically the control board is screaming that it can't tell if the fan is doing anything. That fan moves cold air from the freezer coils into the fridge section, so when it dies, you've got a really expensive box. This is one of the more common codes I see on Kenmore Elite side-by-sides and French doors, probably because LG makes the guts of most of these and the fan motor design has a known weakness with moisture over time.

Control Board or Wiring Issues10%
Symptoms You May Notice
Your fridge section creeps up to 50 or 60 degrees while the freezer itself still feels partially cold.
A grinding or chirping noise from the back wall of the freezer, usually worse at night when the house is quiet.
Er FF flashing on the display, sometimes alternating with the temperature reading.
Ice cream gone soft and soupy even though the freezer doesn't feel obviously warm yet.
You open the crisper drawer and a wave of warm air hits you from the back of the fresh food section.
Can you reset a Kenmore refrigerator to clear the Er FF code?
Unplug the refrigerator from the wall. Wait at least 60 seconds, though 10 minutes is better on these Kenmore boards. Plug it back in and listen for the fan to start within 30 seconds. If the code doesn't come back and you can feel cold air moving in the fridge section after 15 minutes, you're good. If it comes right back, the board's still detecting a real problem and a reset alone won't fix it.

Frequently Asked Questions
Can I just defrost the fridge to fix Er FF?
Yeah, sometimes. If the code came from ice jamming the blades, a full manual defrost clears it right up. Unplug the whole unit and let it thaw for 24 hours with the doors open and towels on the floor. But here's the thing, if your defrost heater or defrost thermostat is bad, that ice is coming back in about a week and you'll be staring at Er FF again. So defrost it, check the door seals, and watch it closely. If frost comes back fast, you've got a defrost system failure on top of the fan issue.
Is Er FF the same as Er IF on a Kenmore?
Nope, totally different fans. Er FF is the main freezer evaporator fan, which keeps both the freezer and fridge sections cold. When that one goes, your food's in real trouble. Er IF or Er 1F is the ice room fan, which just circulates air around the ice maker. Way less critical. Er FF is the one that'll have you throwing out a hundred bucks worth of groceries if you sit on it.
Where exactly is the freezer fan located?
It's mounted behind the back interior wall of the freezer, directly above the evaporator coils. You can't see it without pulling the panel off. Empty everything out, remove the shelves and drawers, and you'll find a plastic panel with screws on the back wall. The fan is right there behind it. On most Kenmore Elite models it's in the upper-center area of that back panel.
How much does a replacement fan motor cost?
The part itself runs $50 to $100. Common LG-platform motor part numbers used in Kenmore units include EAU61524002 and EAU36326507, but pull your model number before ordering. If you're paying a tech, figure $200 to $300 total with labor. It's an hour's work or less once you know what you're doing. If your fridge is already 10+ years old and the compressor sounds rough, it's worth having the repair vs. replace conversation before you spend the money.
Why does my Kenmore keep getting ice around the fan?
Almost always one of three things. Bad door gasket letting warm humid air in constantly. Clogged defrost drain so the meltwater from defrost cycles has nowhere to go and just refreezes right there. Or a failed defrost heater or thermostat that's not running defrost cycles at all. I clear the drain with hot water and a turkey baster on basically every one of these calls. It's a 10-minute fix that most people never think about. Check your door seal by closing the door on a dollar bill. If you can pull it out easily, that seal's shot.
How long does this repair take if I'm doing it myself?
If you've got the right tools and you're comfortable with basic appliance work, plan on 1.5 to 2 hours. Half of that is just waiting for frost to melt if there's ice buildup. The actual motor swap is maybe 20 minutes once you've got the panel off. Getting that back panel off and back on without cracking the plastic clips is honestly the hardest part. Go slow on those clips, they're brittle on older units.
