Keys Health 08-0050 Treadmill Controller

Keys Health 08‑0050 is a high‑current treadmill motor controller power supply rated at 120 VAC input and –100 VDC/14.5 A output. Common failures on this model include burnt or tripped internal fuses, degraded capacitors in the DC filtering stage, and overheating of the switching regulator due to poor ventilation. Begin troubleshooting by verifying the 120 VAC supply voltage, checking for a live output at the –100 VDC terminals with a multimeter, and inspecting the board for visual signs of component damage or thermal stress; if these checks are normal, review any error codes displayed on the treadmill’s diagnostic panel before proceeding to internal fuse replacement.[oss-gpt-20b]
