Digital Concepts 350HRCB circuit board

Digital Concepts 350HRCB is a compact industrial controller board typically found on treadmill lower‑motor assemblies and other high‑current motor drives. Common failure points include electrolytic capacitor degradation, cracked or cold solder joints on the power‑stage ICs, and burnt traces from over‑voltage spikes; firmware corruption can also trigger erratic operation. First‑check diagnostics: verify 24 V DC input voltage and polarity, inspect for visible burn marks or bulging capacitors, and read any diagnostic LEDs or error codes displayed by the board.[oss-gpt-20b]
