KONE LCECCBe Car Roof Board KM50025436G01 G11 G31 G32 G33

When a technician removes an electronic board from the top of an elevator car, the first task is usually not replacing it immediately—it is recording exactly what has been installed.

The LCECCBe board is mounted on the car roof of compatible KONE elevator systems. Since several assembly revisions share a very similar appearance, keeping accurate identification records before disconnecting the wiring can save considerable time during replacement. Public spare-parts references list KM50025436G01, G11, G31, G32 and G33 as members of the LCECCBe family.

Create a Simple Identification Record

Instead of removing the board straight away, it is helpful to make a quick record with a mobile phone.

A good record normally includes:

• complete KM50025436Gxx label

• KM50025437H02 or KM50025437H08 PCB marking

• overall installation photo

• connector positions

• cable routing

• terminal numbers

• nearby modules

• elevator model

• controller type

• quantity required

These photographs are often more valuable than a written description because they preserve the original installation condition.

Don't Judge by the Board Shape

Many LCECCBe boards have almost identical dimensions. However, different production batches may contain different electronic components, connector layouts or hardware revisions.

Before preparing a replacement, compare:

• assembly reference

• PCB number

• connector orientation

• populated components

• jumper locations

• repair labels

• signs of overheating

• damaged terminals

If the original board has already been repaired or modified, this information should also be provided before quotation.

Besides checking the PCB itself, technicians should inspect the car-top wiring harness, grounding points and connector terminals. A loose connector or damaged cable can produce symptoms similar to a board failure.

Frequently Asked Questions

What is the difference between KM50025436G31 and KM50025437H02?

Generally, KM50025436Gxx identifies the complete PCB assembly, while KM50025437H02 or H08 is the hardware number printed on the circuit board. Both references should be confirmed together before ordering.

Are G01, G11, G31, G32 and G33 interchangeable?

Not necessarily. They belong to the same LCECCBe family, but different assembly revisions may have hardware differences. The original board should always be matched before replacement.

Why is an installation photo important?

An installation photo records connector locations, wiring direction and surrounding modules. These details are often unavailable once the board has been removed.

Is this the main controller?

No. The LCECCBe is installed on the car roof as part of the elevator's distributed control system. It is different from the main controller located inside the control cabinet.
