The Marantec 122946 Housing Set is a genuine OEM replacement enclosure for select Marantec garage door opener components. Designed to restore the protective outer shell of compatible operator assemblies, this housing set helps shield internal electronics from dust and incidental contact while returning the system to a clean, factory appearance. It is intended for service and repair on applicable Marantec operator platforms identified to use part number 122946, supporting reliable operation in residential or light commercial applications.
Use this housing set when the original cover is cracked, missing, or worn. For compatibility, verify your opener’s parts diagram or the component label to confirm p/n 122946 is specified for your exact model (including select Synergy or Comfort series where indicated by Marantec). Installation is typically straightforward: disconnect power to the opener, remove the existing cover, and fit the replacement housing with the original fasteners or those provided with the kit; no programming is required since this is a passive enclosure. Always unplug the operator and secure the door before servicing, and test for smooth operation after reassembly.
