Ask a Question
  • Can I see the sprocket replacement instructions before I buy the sprocket, to make sure I can do it?

    You can view the sprocket replacement instructions here.

  • I have 2042 opener, will the opener need to be removed to change the sprocket

    It is recommended in the instructions to take it down whole replacing the sprocket.

  • I have a 0.5 HP Promax garage door opener that I am considering replacing. Does Genie sell a 0.5 HP garage door opener with a battery backup that I purchase in California. I have only been able to find a 2 HPc that I believe is way more powerful than I need, even though my door is a single piece and not a sectional type. If so, please let me know what the name and model number are so that I can order one.

    The 2Hpc Machforce is the only one sold in retail right now with a battery back-up that will work on a one-piece garage door. You can contact a local Genie garage door dealer in your area for other options. If you visit and enter your zip code you can locate dealers in your area.

  • Does this also work with the Genie 1024 Pro?

    Yes, 14 Tooth Belt Sprocket - 38416A.S works with the 1024 Pro.

  • Will this sprocket fit a ReliaG650??

    Hello. No, this sprocket will not work with your opener. You would need the 37558R.S sprocket for your belt drive 1028 Genie ReliaG 650 opener.
