The LiftMaster K79-15016-1 RPM Sensor Kit is an OEM replacement assembly designed to restore accurate rotational feedback in select LiftMaster commercial door operators. By monitoring motor shaft rotation and sending pulse signals to the control board, this RPM/encoder sensor enables precise door travel, speed detection, and direction monitoring, helping the operator maintain consistent performance and fault detection. It’s a direct replacement for a failed or erratic RPM sensor, commonly used in commercial and industrial overhead door applications where reliable operator feedback is required for safe, consistent operation.
This kit is intended for compatible LiftMaster commercial operators (such as select jackshaft, trolley, hoist, and gear-reduced models) that utilize an external RPM feedback sensor. Installation typically involves mounting the sensor at the designated bracket near the motor or encoder wheel and connecting the included harness to the logic/control board. Always disconnect power and follow lockout/tagout procedures, then perform any model-specific setup or limit recheck recommended in the operator’s service manual after replacement. Use in appropriate indoor environments and verify compatibility by part number against your operator’s documentation or LiftMaster technical support before purchase.
