What Er rF means on a Kenmore refrigerator
Er rF indicates the refrigerator control board did not receive a feedback signal from the BLDC (brushless DC) fan motor within a 65-second window during operation. The control board continuously monitors the fan motor's feedback signal to confirm the motor is spinning at the correct speed. When that signal is absent for 65 seconds, the board logs this fault. The three most likely hardware causes are a failed or disconnected wiring harness to the BLDC motor, a faulty drive IC, or a failed transistor (TR) in the motor drive circuit.
For homeowners: this code means the refrigerator's internal fan motor is not communicating back to the main board. The fan circulates cold air throughout the refrigerator compartment. If the fan is not running or not being detected, the refrigerator may lose cooling efficiency or stop cooling altogether. This is not a minor warning to ignore.
The code does not self-resolve through power cycling in most cases because the underlying electrical fault persists. Diagnosis starts at the BLDC motor connector and works outward to the drive IC and TR components on the control board.

Common causes of Er rF
- 01
Loose or damaged BLDC motor wiring connection
Wiring / connectionIf the wiring harness connector to the BLDC fan motor is loose, corroded, or has a broken wire, the feedback signal cannot reach the control board. This interrupts the 65-second monitoring window and triggers Er rF.
- 02
Failed BLDC fan motor
Part replacementThe brushless DC fan motor itself can fail mechanically or electrically, preventing it from spinning and sending no feedback signal back to the board. A seized or burned-out motor must be replaced to clear this fault.
- 03
Faulty drive IC in the motor control circuit
Part replacementThe drive IC is the integrated circuit responsible for converting control board commands into the signals that power the BLDC motor. If the drive IC fails, the motor receives no proper drive signal and produces no feedback, triggering this error.
- 04
Failed transistor (TR) in the motor drive circuit
Part replacementThe TR (transistor) works alongside the drive IC to switch power to the BLDC motor coils. A shorted or open transistor breaks the motor drive circuit, preventing motor operation and eliminating the feedback signal the board expects.
