Samsung Air Conditioner Error Code E160

E160 indicates that the indoor unit fan motor failed to start correctly and no RPM feedback was returned to the MICOM control board. The system uses a PID control style fan motor with a HALL IC sensor that sends rotation pulses back to the board. When those pulses are absent during startup, the MICOM logs E160 and shuts down to prevent damage. The fault points to the HALL IC connector, the sensor itself, or the fan motor.

No. When E160 is active, the unit has already shut itself down because the indoor fan motor did not start properly. Attempting to restart and run the system repeatedly without diagnosing the fault can stress the motor windings and the control board. It is best to leave the unit off until the root cause is identified and corrected.

Repair costs depend on which component has failed. Connector reseating or minor wiring repairs are generally low cost and may only involve a service call fee in the range of $75 to $150. Replacing the HALL IC sensor or fan motor typically adds parts costs ranging from $50 to $300 or more depending on the unit model. A full control board replacement represents the higher end of repair costs.

A knowledgeable DIYer can start by checking whether the HALL IC connector is properly seated and free of corrosion or damage, as a loose connection is a common cause. However, testing the HALL IC sensor output, diagnosing motor winding faults, and replacing internal components typically require electrical knowledge and proper tools. If the motor or control board needs replacement, professional service is recommended.

A power reset may temporarily clear the error display and allow the unit to attempt a restart, but if the underlying problem persists, E160 will return as soon as the MICOM fails to receive RPM feedback again. A reset is not a fix. The fault will continue to recur until the HALL IC connector, sensor, wiring, or motor is properly diagnosed and repaired.
