KONE LCECPUnc Board KM763640G01  KM763643H03 H04

KONE KM763640G01 is an LCECPUnc control board used with compatible KONE V3F18 elevator systems. KONE’s official part description is PCB, LCECPU NC Board V3F18. The original PCB may carry the printed reference 763643H03 or 763643H04.

This board is often removed from the controller after a technician has already checked the elevator fault history. At that point, the important question is not simply whether another board is marked “LCECPU.” The complete assembly number, PCB revision and configuration components must be compared.

What Should Be Visible in the Photos?

A useful enquiry normally includes three photographs:

1. One complete front view of the PCB

2. One close-up of the KM763640G01 label

3. One close-up showing 763643H03 or 763643H04

Photos should also show the connector positions, memory or parameter devices, and any removable chips fitted to the original board. Some replacement boards may require information or components to be transferred from the removed PCB, so these areas should be checked before shipment. One market listing for the H04 version specifically notes a removable configuration chip arrangement, although the exact setup must be confirmed from the customer’s original board.

H03 and H04 Are Not Just Extra Numbers

The H03 and H04 references belong to the same LCECPUnc family, but they may represent different PCB revisions. They should not be assumed to be interchangeable without comparing:

• KM763640G01 assembly number

• 763643H03 or 763643H04 marking

• board component layout

• connector arrangement

• installed chips or memory devices

• V3F18 drive information

• elevator platform

• original fault description

The KM763640G01 board is associated with KONE V3F18 and appears in several KONE machine-room-less elevator families, including selected MonoSpace-related platforms.

Before installing another board, technicians should inspect the power supply, grounding, communication connections, plugs and nearby LCE modules. Programming, parameter transfer and final testing should be completed by qualified elevator personnel.

For orders from Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Colombia, Spain and Italy, sending the complete old-board photographs before quotation helps reduce errors between H03 and H04 versions.

Frequently Asked Questions

Is KM763640G01 the complete inverter?

No. KM763640G01 is an LCECPUnc PCB used with compatible V3F18 systems. It is an internal control board, not the complete inverter or elevator controller.

Can 763643H03 replace 763643H04 directly?

Not necessarily. Both numbers are associated with the KM763640G01 LCECPUnc family, but the PCB revision, component layout and configuration should be checked before replacement.

What information is needed before quotation?

Please provide the KM763640G01 label, the H03 or H04 PCB marking, complete front and rear photos, connector close-ups, the V3F18 or controller information, and photos of any removable chips fitted to the old board.
