KONE KCEFCB Assembly KM50014542G11 G19 G21

A customer may send a photo showing “KCEFCB” clearly, while the last part of the assembly number is hidden by a cable, handwritten label or old repair sticker. For this board family, that missing G-number matters.

KONE identifies KM50014542G11, KM50014542G19 and KM50014542G21 as KCEFCB assemblies. They belong to the same PCB family, but the exact version installed in the elevator should be confirmed before a replacement is selected.

Start With the Assembly Label

The best identification photo is a close-up taken directly above the original label. It should show the full reference without glare:

• KM50014542G11

• KM50014542G19

• KM50014542G21

After the label is recorded, compare the complete PCB rather than one connector or one corner of the board. Component population, connector arrangement, terminal markings and hardware revision can help distinguish boards that otherwise look very similar.

For quotation, please provide:

• complete KM50014542 G-number

• clear front and rear photos

• close-ups of every connector area

• any PCB number printed on the board

• elevator model or controller family

• cabinet installation photo

• details of previous repair work

• visible burn, corrosion or connector damage

• required quantity

Why the G-Number Should Not Be Ignored

A matching family name does not prove direct interchangeability. G11, G19 and G21 should be checked against the original installation, especially when the replacement board comes from another elevator or has already been repaired.

Before fitting the PCB, technicians should inspect the plugs, power supply, grounding and nearby wiring. If the removed board failed after a short circuit or voltage problem, replacing the PCB without correcting the original cause may damage the replacement.

Programming, setup and final elevator testing should be completed by qualified personnel.

For enquiries from Saudi Arabia, Jordan, Egypt, Iraq, Lebanon, UAE, Brazil, Chile, Spain and Italy, a readable label photo together with one complete board image is normally enough for an initial version review.

Frequently Asked Questions

Are KM50014542G11, G19 and G21 the same board?

They are all identified as KCEFCB assemblies, but they are different assembly references. Direct replacement should only be considered after the original G-number, board layout and elevator configuration have been checked.

Can I order it with only the name KCEFCB?

It is not recommended. Please provide the full KM50014542Gxx number because the family name alone does not identify the installed version.

Is KM50014542G21 the complete controller?

No. It is a PCB assembly used within a compatible KONE controller and electrification system, not the complete controller cabinet.
