Ask a Question
  • About to Order SKU: 33950S.S My MODEL # GCG350L IS CHAIN DRIVE and the SWITCH IS MANUAL NOT MAGNETIC … Will SKU: 33950S.S Work ???? It specifically states Screw Drive and my Model is not listed. Thanks LSK

    No, you cannot use any other limit switch, the limit switch for the Genie model GCG350L is no longer available.  The part number was 20467R.S if you would like to find from locale dealers using our dealer locator or other online sources.

  • 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.
