Repair Guide

How to Fix Error Er FF

1

Power cycle the appliance

Unplug for 5 minutes and plug back in. A temporary glitch may have triggered the error.
2

Listen for the fan

After plugging back in, listen near the fan location. If you hear grinding, clicking, or nothing at all, the motor or blades have an issue.
3

Check for ice buildup

Open the panel covering the fan (usually the back wall inside the compartment). If you see ice around the blades, defrost manually using a hair dryer on low.

Never use sharp objects to chip ice — you can puncture refrigerant lines.
4

Spin the fan by hand

With the appliance unplugged, try rotating the fan blade. It should spin freely with slight resistance. If it's stiff or locked, the motor bearings are seized.
5

Check wiring

Disconnect and firmly reseat the fan motor connector at both the motor and the control board ends.
6

Replace the fan motor

If the motor is confirmed bad, order a replacement for your model. Most fan motors are held by 2-4 screws and a single wire connector.
