Possible Causes
Faulty internal Hall sensor or tachometer in DAB motor, Damaged feedback wiring between motor and inverter, Loose connector on control PCB, Inverter firmware fault
How to Fix / Troubleshooting
Safety first: Disconnect power before opening any covers.
Steps to check:
- Inspect motor feedback cable: On some DAB variable‑speed models, a low‑voltage harness connects the motor to the control module. Check for cuts, rodent damage, or pulled connectors.
- Reseat connectors: Gently unplug and replug the feedback connector on the inverter/control board to ensure good contact.
- Power cycle and reset: Turn power off for 5 minutes, then back on. Clear E07 and attempt to change speed.
- If E07 returns immediately: The internal speed sensor or control board is likely defective. These are not usually user‑serviceable; replace the motor assembly or inverter/control module as specified by DAB.
