## Star Trac Treadmill Fan Power Supply Board BP580

The Star Trac 9-7631-MUSAPO treadmill fan power supply board is a pre-owned lower control board designed to power the motor compartment fan in compatible Star Trac commercial treadmills. This replacement board carries part number 715-3621 and SKU BP580. If the fan in your treadmill no longer operates, this board may help restore the cooling system and support reliable equipment operation.

Product Details and Benefits

This Star Trac fan power supply board controls power to the treadmill’s motor compartment fan. During regular use, the fan helps move heat away from the motor and electronic components. Replacing a faulty or damaged board can restore the fan’s power supply and help the treadmill maintain its intended cooling function.

The board is identified by the following numbers:

- **Brand:** Star Trac
- **Product type:** Treadmill fan power supply board
- **Board category:** Lower control board
- **Star Trac part number:** 9-7631-MUSAPO
- **Alternate part number:** 715-3621
- **SKU:** BP580
- **Condition:** Pre-owned

This is an authentic Star Trac replacement component sourced from decommissioned commercial-grade equipment. The board has been inspected and tested before sale. Its pre-owned condition offers a practical way to repair existing fitness equipment while extending the useful life of the treadmill and reducing the need to replace larger assemblies.

A functioning fan power board supports airflow through the motor compartment. That airflow helps manage heat during walking, running, and other treadmill workouts. Restoring the fan circuit can also help the equipment operate as intended when the original board has failed.

Compatibility and Applications

The BP580 board is designed for use with compatible **Star Trac treadmills** that require the **9-7631-MUSAPO** or **715-3621** fan power supply board. It serves as a replacement for the original board that powers the treadmill’s motor compartment fan.

This part is intended for repair and maintenance of Star Trac commercial-grade treadmill equipment. It is not a universal treadmill control board, and compatibility depends on the board installed in your machine. Compare the part number, board markings, connectors, and mounting arrangement with your existing component before ordering.

## Why Choose This Replacement Board?

A tested pre-owned board can provide a cost-conscious repair option when a treadmill’s fan power circuit stops working. Using the correct replacement board may restore the original fan function without replacing the entire treadmill or a larger control assembly. The Star Trac identification and matching part numbers make it easier to confirm whether this component suits your repair project.

Before You Buy

Check your treadmill’s existing fan power supply board and confirm that it shows **9-7631-MUSAPO** or **715-3621**. Also compare the connector layout and mounting points before purchase. The product is sold as a **pre-owned Star Trac lower control board**, SKU **BP580**. Installation requirements and additional included components are not specified, so have the replacement fitted by a qualified service professional if you are unsure about treadmill electronics or wiring.
