What E FF means on a Kenmore refrigerator

The E FF error code on a Kenmore refrigerator indicates a freezer evaporator fan motor fault. The freezer evaporator fan is responsible for circulating cold air over the evaporator coils and distributing it throughout the freezer and fresh food compartments. When the control board detects that the fan motor is not operating within expected parameters, it triggers the E FF code and may reduce cooling efficiency or shut down the compressor cycle to protect the system.

Diagnosing this error begins with a reset of the unit, followed by entering Test Mode 1 by pressing the test button one time. In this mode, the technician should check for proper airflow at the fan location and measure voltage at CON7 pins 10 and 12 on the wiring harness. If voltage is present at those pins but the fan is not spinning, the motor itself is likely failed. If voltage is absent, the fault points upstream toward the wiring, connectors, or the main control board.

Common root causes include a seized or burned-out fan motor, ice buildup around the fan blade preventing rotation, damaged wiring between the control board and the motor, or a failed main control board that is not supplying proper voltage to the fan circuit. Ice accumulation is especially common and can result from a defrost system failure that allows frost to build up around the evaporator assembly and obstruct or jam the fan blade.

Common causes of E FF

  1. 01

    Ice buildup jamming the fan blade

    Wiring / connection

    Frost accumulation around the evaporator can physically block or seize the fan blade. Check for visible ice around the fan assembly after removing the back panel inside the freezer.

  2. 02

    Failed freezer evaporator fan motor

    Part replacement

    The motor windings can burn out or the motor can seize mechanically over time. If voltage is confirmed at CON7 pins 10 and 12 but the fan does not spin, the motor needs replacement.

  3. 03

    Broken or disconnected wiring to the fan motor

    Wiring / connection

    Wires running to the fan motor can become brittle, chafed, or disconnected, especially near the door hinge area. Inspect the harness from the control board to CON7 for damage or loose connections.

  4. 04

    Faulty main control board

    Part replacement

    If no voltage is present at CON7 pins 10 and 12 during Test Mode 1 and the wiring checks out, the control board may not be supplying power to the fan circuit. This requires board replacement.

  5. 05

    Defrost system failure causing secondary fan obstruction

    Part replacement

    A failed defrost heater or defrost thermostat can allow excessive frost to accumulate on the evaporator coils, which eventually restricts airflow and can jam the fan. Resolving the E FF code may require addressing the underlying defrost fault as well.

Frequently asked questions about E FF

What does E FF mean on a Kenmore refrigerator?
E FF is a freezer evaporator fan motor error code. It means the control board has detected that the freezer fan motor is not operating properly. This fan circulates cold air throughout the freezer and fresh food compartments, so when it fails, cooling performance drops noticeably. The code can be triggered by a seized motor, ice obstruction, wiring faults, or a bad control board.
Can I fix the E FF error myself?
Some causes of the E FF code are DIY-friendly. If ice is blocking the fan blade, manually defrosting the freezer by unplugging the unit for 24 to 48 hours can clear the obstruction without any parts. Checking wiring connections at CON7 is also manageable for someone comfortable with basic electrical work. However, replacing the fan motor or control board typically requires disassembly of the freezer interior and some technical skill.
Is it safe to keep using my refrigerator when E FF is showing?
It is not recommended to continue using the refrigerator normally when the E FF code is active. Without the evaporator fan running, the freezer and fresh food sections will not maintain safe temperatures, which can lead to food spoilage. You should address the fault promptly or transfer perishables to another unit while diagnosing the problem.
Will resetting the refrigerator clear the E FF error?
A reset may temporarily clear the code, but if the underlying fault is still present, the E FF error will return. The reset is most useful as a first diagnostic step to rule out a one-time glitch. If the code comes back after a reset, proceed with checking the fan motor and voltage at CON7 pins 10 and 12 using Test Mode 1.
How much does it cost to repair a Kenmore refrigerator showing the E FF code?
Repair costs depend on the root cause. A manual defrost to clear an ice jam costs nothing beyond your time. Replacing a freezer evaporator fan motor typically runs between $80 and $200 in parts, plus labor if a technician is hired. A main control board replacement is more expensive, generally ranging from $150 to $350 or more for parts alone, and professional labor will add to that total.
