LiftMaster K108D0077M Light Lens Cover for Residential Garage Openers
The K108D0077M is a replacement light lens cover used on select residential garage door openers. The lens covers the opener light area, helps protect the bulb area, and spreads light more evenly around the garage.
Light lenses are commonly replaced when they crack, discolor, warp from bulb heat, fall off, or break when changing bulbs. A missing lens can leave the opener looking unfinished and may expose the bulb area to dust or accidental contact.
Compatibility is based on opener housing design, lens shape, mounting tabs, and the original lens part number. This lens is commonly associated with LiftMaster and Chamberlain residential opener applications and related numbers 108D67, 108D0077M, 108D0077, and 108D77. It should be verified against the opener parts diagram because similar light covers are not always interchangeable.

Technician Note
If the old lens warped or yellowed badly, check the bulb type and wattage used in the opener. Excessive heat from the wrong bulb can damage plastic covers and nearby opener components.
Before Ordering
- Match the original lens number to K108D0077M, 108D0077M, 108D0077, 108D77, or 108D67.
- Confirm the lens shape and mounting tabs match the opener housing.
- Check the opener parts diagram when the original lens is missing.
- Inspect the bulb type and wattage to reduce heat damage to the new lens.
- Do not force the lens into place if the tabs do not line up.
Important Ordering Warnings
- LiftMaster and Chamberlain light lenses are not universal by brand.
- Similar-looking lenses can have different tab locations or dimensions.
- A heat-damaged lens may indicate the wrong bulb wattage or bulb type was used.
Professional Advisory
Light lens replacement is usually straightforward, but if the opener housing, socket, or wiring shows heat damage, have the opener inspected by a qualified garage door technician before continued use.

Age, heat, and incorrect bulb wattage can discolor or weaken plastic light lenses over time.
Does this include the light bulb or socket?
