Pro-Form Performance 400i Treadmill Lower Motor Control Board MC1618DLS (BP551)

## ProForm Performance 400i Treadmill Lower Motor Control Board MC1618DLS (BP551)

The ProForm Performance 400i Treadmill Lower Motor Control Board MC1618DLS (BP551) is a replacement lower control board for the ProForm Performance 400i treadmill. This electronic component helps control the treadmill’s lower motor system during operation. If the original motor control board has failed or no longer functions correctly, replacing it with the matching board may help restore the treadmill’s motor control functions.

Product Details and Benefits

This product is a lower motor control board, also called a lower control board or motor controller. It forms part of the treadmill’s lower electrical system and manages the signals and power associated with the drive motor. The board works with the treadmill’s control system to support normal motor operation.

The product name identifies the board as an MC1618DLS unit, with the part number BP551. These identifiers help you compare the replacement with the board currently installed in your treadmill. Matching the part number matters because control boards can differ between treadmill models and production versions.

A correctly matched replacement board can help address problems caused by a defective or damaged original board. Depending on the fault, symptoms may include a motor that does not run, inconsistent motor operation, or a treadmill that cannot respond properly to speed commands. The board itself does not replace the treadmill motor, walking belt, console, or power supply. It replaces the lower motor control board component.

Compatibility and Applications

This replacement part is listed for the **ProForm Performance 400i treadmill**. It is identified as the **MC1618DLS lower motor control board** and carries the product part number **BP551**.

Use this board for repair or replacement work on a compatible ProForm Performance 400i treadmill. Before ordering, compare the part number and board markings on your existing component. The treadmill model name alone may not confirm compatibility if the manufacturer used more than one board version during production.

This item is intended for treadmill repair and is most suitable for customers, service technicians, and equipment repair businesses replacing a failed lower control board. It is an electronic replacement component, so installation should be completed by someone familiar with treadmill electrical systems and safe equipment repair procedures.

### Why Choose This Replacement Board?

Choosing a matching lower motor control board allows you to replace the failed control component instead of replacing the entire treadmill. Using the correct board number can reduce the risk of ordering an incompatible part and helps ensure that the replacement matches the treadmill’s original electrical system.

The BP551 identification also makes it easier to compare this component with repair records, service information, or the label on the existing board. Confirming the board number before purchase gives you a more reliable way to determine whether this is the correct replacement.
