Mitsubishi Door Operator Board P231709B000G03 P231715B000G02

Mitsubishi Door Operator Board P231709B000G03 / P231715B000G02 is used in Mitsubishi elevator door machine and door operator control systems.

This board is commonly searched in the elevator spare parts market as a door motor controller board, door operator PCB, door drive board, or door motor control PCB. It is usually related to the electrical control of elevator door opening, closing, speed response, and door motor operation.

For this product, both model references should be checked carefully:

• P231709B000G03
• P231715B000G02

Although these numbers may appear together in market listings, the final replacement should still be confirmed by the old board label, connector layout, and door operator configuration.

Model References Commonly Found

This page can naturally cover the following related model numbers:

• P231707B000G03
• P231709B000G03
• P231709B000G13
• P231709B000G23

• P231715B000G43
• P231715B000G53
• P231715B000G99

Public supplier pages often list these models under Mitsubishi elevator door motor controller board, Mitsubishi lift door operator PCB, or Mitsubishi LEHY-3 elevator door drive board descriptions. These model numbers are useful for search coverage and quotation matching, but they should not be treated as automatically interchangeable without checking the original board.

How This Board Is Usually Identified

Door operator boards are often identified from the old PCB rather than from the elevator model alone.

A customer may describe this part as:

• Door operator board
• Door motor controller board
• Door drive board
• Door control PCB
• LEHY-3 door drive board

These names may refer to the same door control area, but the exact PCB number is still the most important reference.

For accurate confirmation, buyers should check the printed board number first, then compare connector position, board size, and installation position inside the door operator system.

Door Problems That May Lead to Inspection

Maintenance teams may inspect this board when the elevator door has symptoms such as:

• Door opening failure
• Door closing timeout
• Door speed instability
• Door motor not responding
• Repeated door reopening
• Door operation fault indication
• Abnormal response after power-on

These symptoms are not always caused by the board itself. The door motor, encoder feedback, door belt, pulley, hanger rollers, light curtain, and mechanical resistance should also be checked before confirming the PCB fault.

What to Confirm Before Supply

Before ordering, please provide:

• Clear photo of the old board label
• Front and back photos of the PCB
• Connector area photo
• Door operator installation photo
• Door motor label if available
• Existing door fault description
• Whether the old board shows P231709, P231707, or P231715 series marking

This helps confirm whether the required board is P231709B000G03, P231715B000G02, or another related Mitsubishi door operator board version.

Practical Replacement Note

Do not select this board only by appearance.

The P231709 and P231715 series may have similar market descriptions, but the suffix such as G02, G03, G12, G23, G33, or G53 may indicate a different version or application configuration.

Before installation, technicians should compare the old and new board carefully and check the door operator wiring, motor condition, encoder signal, and mechanical door movement. If the old board was damaged by motor overload, wiring short circuit, unstable power, or mechanical resistance, replacing only the PCB may not fully solve the door issue.

For overseas buyers, matching the exact printed PCB number and connector layout is the safest way to avoid wrong supply.
