If you can't get what you seek from the manufacturer [use the contact information at https://www.contacthelp.com/liftmaster/customer-service], request a part number. Then (with a part number if possible) try
- https://encompass.com/
- https://www.diyspareparts.com/
- a search engine like Google's or Bing
- http://www.searchtempest.com/, which displays global listings from eBay, Craigslist, and other sources
(For option 3, you may want to use a free tracking program like https://www.followthatpage.com/ to save you from having to repeat your search over time.)
Hope this is useful. Please don't forget to click the Accept This Answer button if you do accept it. My aim is to provide reliable helpful answers, not just a lot of them. See https://www.helpowl.com/profile/Odin.
