    Performing a pump drive repair requires a careful, step-by-step diagnostic process to resolve electrical, thermal, and mechanical issues safely. Prioritizing safety, technicians must isolate power and allow the DC bus capacitors to fully discharge before opening the enclosure. Once safe, a thorough visual inspection can highlight common failures like swollen capacitors, burnt traces, or dust-choked cooling fins that trigger thermal trips.
