LiftMaster K1D6761-1CC / K1D6761-1CCMC AC Gate Operator Logic Board

The LiftMaster K1D6761-1CC is an AC gate-operator logic-board service reference. The supplier identifies the offered manufacturer number as K1D6761-1CCMC, so both the board number and the equipment revision should be checked before purchase. This board manages operator controls in the applicable system; it is not the motor power-supply board or a universal controller for all LiftMaster gates. Match it to the exact operator parts list and confirm any approved replacement relationship before removing the original electronics.

Compatibility — Models, Versions and Exclusions

Identify the Board and Diagnose the Original Fault

An operator that does not respond may have a supply, fuse, wiring, accessory or mechanical problem rather than a failed logic board. Have a technician record diagnostic indications and check the system before selecting replacement electronics. A defective accessory connection or damaged wiring can remain a problem after the board is changed and may damage the replacement.

Provide clear photographs of the existing board label, the operator model label and the installed connections. Older equipment may contain parts fitted during previous service, so the enclosure label alone may not identify every internal revision. Confirm how settings, limits and accessories must be commissioned after replacement; do not assume the old setup transfers automatically.

Specifications and Product Identification

Before Ordering

• Read the full operator model, serial information and original board reference.
• Confirm the supplier’s MC-suffix board is the approved service replacement for that assembly.
• Have the supply and connected accessories checked before fitting new electronics.
• Identify any required programming, limit setup and safety-device checks in the applicable manual.

Package Contents and Separate Requirements

This listing identifies the logic-board service item. A complete control enclosure, motor, transformer, power board, radio accessory or wiring harness is not promised as included. Confirm the supplied board and carton contents before ordering. Parts pictured next to the logic board in an exploded diagram should not be treated as part of the same shipment unless the kit inventory expressly includes them.

Safety Warnings — Read Before Installation or Service

• WARNING: AC gate equipment contains hazardous voltage and can move unexpectedly. Board replacement requires a qualified gate-systems technician.
• Disconnect and secure all applicable power sources before touching wiring or removing the board.
• Do not bridge safety inputs or conceal a monitored-device fault to make the replacement board operate.
• Follow the required setup procedure and test travel, reversal and every installed protection device before normal use.

Related Products and Important Differences

• LMRRUL monitored photo eye — consider only if the exact operator and supplied board revision approve it; not a universal retrofit for legacy controls.
• LMWEKITU monitored wireless edge kit — a separate safety accessory requiring documented operator compatibility, not a board repair component.

Frequently Asked Questions

Why are two part-number forms shown?

The source uses K1D6761-1CC as its SKU and K1D6761-1CCMC as the manufacturer reference. Confirm that offered revision against the original assembly.

Is this the same as the motor power board?

No. Logic and motor power components have different functions. Use the parts diagram and diagnosis to identify the required board.

Will it work in every AC LiftMaster gate operator?

No universal fit is established. The exact model, generation and approved service reference must match.

Will the old settings remain after replacement?

Do not assume so. Have the technician follow the model-specific commissioning and accessory setup instructions.
