The LiftMaster K108D0034 is a replacement light lens used on select LiftMaster and Chamberlain residential garage door openers. The light lens covers the lamp area on the opener housing and helps keep the light compartment protected from dust, impact, and accidental contact. This part is commonly replaced when the original lens has become cracked, discolored, brittle, missing, or damaged during bulb service. While a lens may look simple, correct fitment matters because the mounting tabs, curve, length, and latch points have to match the opener housing. Chamberlain Group used many light lens designs across older chain drive, belt drive, and screw drive openers, so the original part number and physical lens shape should be verified before ordering.

A lens should snap or fasten into place without being forced. If the tabs do not line up, stop and compare the original lens shape. Forcing a wrong lens can break the opener cover or the replacement lens.
Unplug the opener before working around the light socket or bulb area. If the socket, wiring, or opener cover is heat-damaged, have the opener inspected before continued use.
Light lenses are not universal. Similar older LiftMaster and Chamberlain openers may use different lens shapes even when the opener housings look alike.
