Samsung Refrigerator Error Code DAMPER-MOTOR

The DAMPER-MOTOR code means the refrigerator's control system could not detect a valid position signal from the damper motor's reed switch during more than one minute of operation. The damper motor is a geared motor that opens and closes an air flap to regulate temperature between compartments. The fault points to a problem in the damper motor itself, its reed switch, the associated magnet, or the control relay that powers the motor.

The refrigerator may continue to run with this code active, but temperature control will be compromised because the damper cannot properly regulate airflow between compartments. Food safety can become a concern if one section becomes too warm. It is best to address the fault promptly and monitor food temperatures closely in the meantime.

Repair costs vary depending on which component has failed. A replacement damper motor assembly typically runs between $30 and $90 for the part, while a reed switch or magnet repair may fall at the lower end of that range. If the control board relay has failed and the board requires replacement, parts alone can range from $80 to $200 or more. Adding professional labor generally brings the total to between $150 and $350 depending on your location and service provider.

Turning the main power off and then back on initiates a self-diagnostic cycle and is the recommended first step. If the underlying fault is intermittent or was caused by a temporary glitch, the code may clear after a reset. However, if a component such as the reed switch, magnet, or motor has physically failed, the code will return once the refrigerator attempts to cycle the damper again.

Start by cycling the main power off and on to trigger the self-diagnostic routine. Then inspect the damper motor assembly for visible damage, check that the magnet on the gear is secure and properly positioned, and test the reed switch for continuity as the motor rotates. Verify the control relay is supplying power to the motor and inspect all wiring harness connections for corrosion or loose pins. Replace any component that fails testing.
