KONE LCECOB Board KM713720G01 G11 G51 G71 713723H04

KONE KM713720G01, KM713720G11, KM713720G51, and KM713720G71 belong to the LCECOB electronic-board family used in compatible KONE elevator car call and operating-panel systems.

KONE officially identifies KM713720G11 and KM713720G71 as LCECOB assemblies within the LCE lift controller and electrification platform. The circuit board may also carry a reference from the 713723H series, such as 713723H04.

Start With the Calls That Are Not Working

When an LCECOB board is suspected, the original fault can provide useful identification information.

For example, technicians may report that certain car calls do not register, several buttons do not illuminate, or the complete operating panel has stopped responding. However, these symptoms do not automatically prove that the PCB is defective. The button wiring, panel power supply, connectors, and communication lines should also be checked.

Before ordering, please provide:

• complete KM713720G01, G11, G51, or G71 assembly label

• full 713723Hxx PCB marking

• LCECOB identification

• front and rear PCB photos

• connector and terminal arrangement

• car operating panel photo

• button quantity and floor configuration

• original installation position

• elevator controller or platform

• fault description

• previous repair information

• quantity required

Why the G-Version Matters

The boards may share a similar outline and connector arrangement, but G01, G11, G51, and G71 should not be treated as automatically interchangeable.

Possible differences may include:

• hardware revision

• component population

• connector definition

• car-call configuration

• communication version

• elevator platform

• replacement or modernization status

The safest approach is to match the complete assembly number together with the PCB marking, connector layout, and original COP configuration.

Before fitting a replacement, technicians should inspect the car-panel wiring harness, button connections, power supply, plugs, grounding, and related LCE modules. A damaged button cable or unstable panel supply can produce symptoms similar to LCECOB failure.

Installation, configuration, and functional testing should be completed by qualified elevator technicians. All car calls, button lamps, door commands, alarm functions, and panel communication should be verified before the elevator returns to service.

For maintenance companies in Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Colombia, Spain, and Italy, complete old-board photos and one image of the full car operating panel are recommended before shipment.

FAQ

Is the LCECOB board the complete car operating panel?

No. It is an electronic PCB assembly used within a compatible car operating or car-call system. The buttons, faceplate, display, wiring, and enclosure are separate components.

Is 713723H04 the complete ordering number?

Usually not. The KM713720Gxx number is generally used as the assembly reference, while 713723H04 or another H-version may be printed directly on the PCB.

Can KM713720G11 replace KM713720G51?

Not automatically. The assembly version, PCB revision, connectors, car-call configuration, and installed elevator system should be checked first.

What should I send before quotation?

Please send the complete G-number label, full 713723Hxx marking, both sides of the PCB, connector close-ups, the complete COP photo, and a description of which buttons or functions are affected.

Is LCECOB the same as LCECEB?

No. LCECOB is associated with car calls and the car operating system, while LCECEB is generally described as an extension-board family. They should not be treated as the same PCB.
