LiftMaster 041B0994 Door Interconnect Cables Kit
The LiftMaster 041B0994 is a door interconnect cable kit for LiftMaster EL2000 series telephone entry systems. These internal cables carry signals and power between the door assembly and the main enclosure components. When the door is opened repeatedly for service, cables can become stressed, pinched, pulled, or damaged at the connector ends, especially in outdoor entry stations exposed to moisture and heat.
This kit is important because a cable problem can mimic a failed keypad, display, speaker, board, camera, or relay. Before replacing higher-cost electronics, the interconnect harness should be inspected for broken conductors, loose plugs, corrosion, and strain at the hinge side of the enclosure. This kit is model-specific and should be used only where the EL2000 parts diagram calls for 041B0994 or related number 41B994.

Technician Note
When an EL2000 has intermittent problems that change as the access door is moved, suspect the door interconnect harness before replacing boards. Secure the cable routing so the replacement harness is not pinched when the door closes.
Before Ordering
- Confirm the original part number on the removed component or parts diagram matches 041B0994 or a listed related number.
- Check the exact access system model and generation before ordering.
- Inspect the enclosure for water intrusion, corrosion, broken tabs, or damaged cable connections before replacing parts.
- Do not substitute similar-looking electronic, camera, lock, or power parts unless the model documentation confirms the match.
- Disconnect power according to the manufacturer instructions before servicing the enclosure.
Professional Advisory
Access control equipment may involve low-voltage wiring, locks, network connections, or power supplies inside a live enclosure. If the system has water intrusion, damaged wiring, unsafe gate movement, or repeated electrical failures, have the installation inspected by a qualified gate or access control technician.
Product Q&A
What system is 041B0994 for?
It is used with LiftMaster EL2000 series telephone entry systems.
What does a door interconnect cable kit do?
It connects internal door-mounted components to the main enclosure electronics so signals and power pass correctly.
Can a bad cable look like a bad board?
Yes. A loose, pinched, or corroded interconnect cable can cause symptoms that seem like display, keypad, speaker, or board failure.
Is this cable kit universal?
No. It should be used only when the parts diagram lists 041B0994 or 41B994 for the system being serviced.
What should be checked during installation?
Check connector orientation, door hinge routing, strain relief, corrosion, and any sharp edges that could damage the new cable.
