The LiftMaster 41A3673 End Panel is a genuine OEM replacement end cover for select LiftMaster garage door opener heads. This component encloses and protects the opener’s electronics and internal wiring at one end of the motor head, helping keep dust and debris out and restoring a secure, finished fit when the original cover is cracked, missing, or damaged. It is designed for direct replacement on compatible LiftMaster units and may also fit equivalent Chamberlain models that share the same part number family.
Use this end panel during routine repairs or housing restoration to maintain proper protection and appearance of the opener. Installation typically involves disconnecting power, removing the light lens and housing screws, transferring any clips or hardware from the old cover, and reattaching the panel to the motor head. Always verify compatibility by checking your opener’s model number and parts diagram or by matching the 41A3673 part number stamped on the original panel. For safety, disconnect power and follow the opener’s service manual before performing any replacement work.
