Dear Community,

I’m trying to repair a treadmill with an ADT-8030 circuit board, but I’m unable to find the exact IGBT model number used on it. Unfortunately, a technician

Details:
  • Board Model: ADT-8030 (common in Chinese-made treadmills).
  • IGBT Missing: No visible markings; likely a TO-247 or TO-220 package.
Request:
  1. If you’ve worked with an ADT-8030 board, could you confirm the IGBT model?
  2. Any suggestions for a generic replacement (1200V/25A+)?
  3. Attached are photos of my board (if possible)—let me know if you spot clues!
Why It Matters:
Without the correct IGBT, the treadmill’s motor driver won’t function. I’d deeply appreciate any guidance or schematics!

Thank you in advance!
