Woodway B3215 is a treadmill controller/driver board (P200) that manages motor speed, torque, and safety interlocks on Woodway Desmo models. Common failure points for this class of industrial treadmill boards include power supply voltage drops or spikes, burned capacitors and electrolytic failures, overheating of the main driver ICs, and loose or corroded I/O connections to the treadmill’s sensors and motor leads. Begin troubleshooting by verifying 24 V DC input stability with a multimeter, inspecting the board for visible signs of component damage (burn marks, swollen caps), and checking all solder joints on the driver ICs and connector pins; then review any logged error codes from the treadmill’s diagnostic display to isolate specific fault conditions.[oss-gpt-20b]
