The Linear 227645 LCO Motor is an OEM replacement motor for select Linear LCO-series light commercial garage door operators. Engineered by Linear (Nortek Control), this drive motor restores reliable lifting torque and smooth operation for compatible LCO operators used on sectional overhead and rolling service doors in applications such as small warehouses, retail facilities, multi-tenant buildings, and loading areas. Use it as a direct replacement when the original LCO motor exhibits symptoms like failure to start, overheating, excessive noise, or inconsistent door movement, ensuring proper integration with the operator’s control system and maintaining factory performance.
Confirm compatibility by matching part number 227645 with your specific Linear LCO operator model and serial information, and review the motor nameplate for electrical ratings and wiring details provided in the official Linear documentation. Installation should be performed by a qualified door operator technician using lockout/tagout procedures, transferring the original mounting components as required, wiring per the Linear schematic to the control board or contactor, and re-tensioning the drive. After installation, reprogram travel limits and force settings and test all entrapment protection devices (photo eyes, monitored edges, emergency release) in accordance with UL 325 and the operator manual. The Linear 227645 LCO Motor is an authentic replacement part for designated LCO operators, supporting commercial and light-industrial use where dependable, long-duty operation is required.
