Technician Note
If the opener light cover keeps falling off, inspect the plastic retaining points on the opener cover. Replacing only the lens will not correct a broken housing tab.
Before Ordering
- Use the manufacturer number K108D0036-2 when matching the current replacement.
- Compare the old lens markings, especially 108D36 or 108D36-2.
- Confirm the opener model and parts diagram for CG40D or CG42D applications.
- Check whether the lens retaining tabs on the opener cover are intact.
- Do not confuse this lens with other Chamberlain light covers that look similar.
Professional Advisory
Do not troubleshoot live wiring in the opener light compartment. If the lens damage was caused by overheating, melted plastic, or a failed socket, have the opener inspected before installing a new cover.
Product Questions & Answers
Why does this row say 108D36-2 if the manufacturer number is K108D0036-2?
108D36-2 is one of the common related numbers for the K108D0036-2 lens family. The K108D0036-2 manufacturer number is the safer number to use when matching the current replacement part.
Is this lens used on Chamberlain CG40D and CG42D openers?
This lens is commonly associated with select Chamberlain CG40D and CG42D style applications, but the original parts diagram should be checked because similar Chamberlain covers are not always interchangeable.
Will this replace both light covers on a dual-light opener?
No. This part listing is for one lens cover. If the opener uses two separate light covers, identify each lens from the parts diagram and order the correct quantity and side when required.
What problem does a replacement lens solve?
It replaces a cracked, loose, cloudy, or missing light cover. It does not repair a light that will not turn on, which may involve the bulb, socket, wiring, relay, or logic board depending on the opener.
Should the opener be unplugged before changing the lens?
Yes. Power should be disconnected before handling the opener light area. Do not work around damaged wiring or overheated sockets unless the opener has been inspected by a qualified technician.
