Parts for the liftmaster CSW200UL3 and CSW200UL8 are the same with the exeption of the enclosure of the control board (the metal box that the board sits in). You can also find the same parts in the Elite CSW200UL category since it's the same operator with a different manufacturer name on it. Here you will find all the best selling parts or most commonly replaced parts including the motor, gear, limit switches and circuit board. Feel free to contact us for any parts you don't see. Happy fixing!
