Yes, the legacy LiftMaster 8550 belt-drive garage door opener has been officially discontinued by the manufacturer, having been superseded by newer generations of belt-drive smart openers featuring updated security encryption and advanced MyQ integration. While the 8550 is no longer manufactured or retailed new, LiftMaster continues to support replacement parts, logic boards, and technical service for existing installed units across residential homes. Verification: Check authorized professional dealer catalogs to confirm that current retail offerings feature newer model designations instead of the legacy 8550.
