The Marantec 104180 Lens Replacement Kit is a genuine OEM light lens cover designed for select Marantec residential garage door openers. It restores the protective and diffusing cover over the opener’s lighting compartment, helping to shield the bulb or LED area from dust and debris while maintaining even illumination in the garage. This replacement part is ideal when the original lens is cracked, yellowed, or missing, and is a direct fit for compatible Marantec operator heads that use the 104180 lens assembly.
Installation is straightforward for most users: disconnect power to the opener, remove the existing lens by releasing the retaining tabs or screws, and secure the new lens in place per the opener’s service manual. No programming or adjustments are required since this is a non-electrical component. For compatibility, consult your opener’s model-specific parts diagram or Marantec America documentation to confirm that part number 104180 is the correct light cover for your unit. Using the correct OEM lens helps preserve proper light diffusion and ensures the lighting compartment remains protected in everyday residential use.
