What Your Machine Is Actually Telling You
F07 means the MCU (Motor Control Unit) self-diagnostics detected a fault in its own power transistors or relay circuits. The MCU controls motor speed, direction, and braking.
Common causes:
1. MCU component failure (30%) — IGBT or relay burned.
2. Power surge (20%).
3. Motor short (15%) — damaged the MCU.
4. Overheating (15%).
5. Loose connections (10%).
6. Software glitch (10%).

What You're Probably Seeing Right Now
- F07 — motor doesn't respond.
- Burning smell from back of machine.
- F07 after a storm or power surge.
- F07 immediately on power-up.
DIY Fix — From Easiest to Hardest
1
Power Reset (10 minutes — Fixes 10%)
1. Unplug for 10 minutes.
2. Plug back in.
3. If F07 clears: temporary.
