Genuine LiftMaster K41-0048-000 reset switch with ID resistor for the HD series heavy-duty gate operators.
Fitment: LiftMaster HDSL24UL heavy-duty slide gate and HDSW24UL heavy-duty swing gate operators. The ID resistor tells the main control board which operator it is fitted to, so a plain reset switch will not work in its place.
Replace when the operator will not reset after an obstruction, or the board reports the wrong operator type.
