The LiftMaster 041C0296 Transformer is a genuine OEM replacement power transformer designed for select LiftMaster garage door openers built by Chamberlain. Installed inside the operator head, this step-down transformer converts incoming line power to the low-voltage supply required by the logic board, radio receiver, safety reversing sensors, and accessories. If your opener has lost power to the control electronics or will not operate after verifying the outlet and wiring, replacing a failed transformer with the 041C0296 can restore proper function. This factory part is engineered for the specific electrical demands of compatible LiftMaster models and may also be used in certain Chamberlain or Sears Craftsman openers that specify 041C0296 on the original component or in the parts manual.
This transformer is not universal; confirm fit by matching the part number on your opener’s parts list or the label on the existing transformer before ordering. Installation typically involves disconnecting power, removing the operator cover, and transferring the primary and secondary leads to the same terminals on the control board, then securing the unit in its original mounting location. Because the transformer connects to line voltage and internal control circuits, safe replacement requires unplugging the opener, observing correct wiring orientation, and following the manufacturer’s service instructions; professional service is recommended if you are unsure. Use this OEM 041C0296 replacement to maintain compatibility, performance, and reliability in residential LiftMaster garage door opener applications that call for this exact part number.
