Ask a Question
  • I bought a down limit switch 33969b for h8000-07 door opener. It did seem to work. Is the same switch as 33950s. If I just hook up wires and touch them together it will stop

    This is the correct limit switch for the H8000-07 model garage door opener. Please contact Genie customer service at 1-800-354-3643 for troubleshooting assistance.

  • What is the difference between 33950S and 33950S.S?

    This would be the same item.

  • I am getting ready to order a replacement Close Limit Sw., P/N 33950S.S, for my Model ISD990. I would also like to order some Wire Clips But I need a Part #.

    The wire clips for the ISD990 would be part number 33905A.S.

  • will this work with model 4560/M?

    Yes, it will.

  • My Genie Excelerator screw drive garage door opener will open, but it DOES NOT CLOSE. I've checked the sensors that detect any objects in the way, but they seem fine (lights indicating no problems). Will a new Down Limit Switch, (138", Brown) - 33950S.S solve my problem?

    This could be a couple of different issues causing the door not to close. For troubleshooting assistance to help determine the problem, please contact Genie customer service at 1-800-354-3643.
