LiftMaster Gate Operator Parts by Model

Find your operator model on the serial label inside the cover — usually on the chassis wall or the inside of the door — then click it below to open a labeled parts diagram. Every part number links straight to the item so you can identify and order in one step. The letters matter: an SL595, an SL595GL and an SL595U are three different operators with different boards and different covers. Match the whole model string, not just the number.

Control Boxes, Electrical Boxes & Arms

Most current LiftMaster gate parts start with a K and a two-digit family code — K74 control boxes, K75 covers and enclosures, K77 harnesses and hardware kits, K94 switches and alarms, K20 motors, K32 gear reducers, K16 belts, K19 chain. Boards are usually K1D or K001 numbers. Older stock is often listed without the K, or with a two-digit prefix instead: 041ASWG-0442SA, 19-3025, 75-G0089, Q079. If a number from your manual returns nothing, try it without the K, without leading zeros, or search the bare digits.

GateHouse Supplies stocks genuine LiftMaster gate operator parts for slide, swing, barrier arm and overhead gate operators — control boards, expansion boards, motors, gear reducers, limit switches and limit chain, clutches, drive sprockets and chain, covers and enclosures, actuator arms, battery harnesses, antennas and solar control boxes. Each model page includes a labeled parts diagram with every part number linked directly to the item, and variants across the UL325 U and UL generations are listed as separate rows inside each page.
