PPG Biomedical Systems 14-3800 B DP Airmeter Exercise Bike

The PPG Biomedical Systems 14‑3800 B DP Airmeter Exercise Bike is a commercial indoor cycling platform that uses an air‑resistance system controlled by a dedicated electronic unit (motor drive, sensor interface, and LCD/LED display). Common failure points in this class of equipment include power supply board faults (brownouts or capacitor degradation), motor driver IC overheating, and loss of communication between the pedal speed sensor and the control logic. First‑check diagnostics should verify that the 120 VAC input is present and stable, inspect the main PCB for burnt components or swollen electrolytics, and confirm that the display and resistance indicators are functioning before proceeding to a deeper I/O and motor drive inspection.[oss-gpt-20b]
