How to Fix / Troubleshooting
Safety: Disconnect power before removing any covers.
- Inspect feedback wiring: Locate the speed feedback or tachometer cable between the motor and the Certikin controller. Check for loose connectors, corrosion, or damaged insulation.
- Check controller parameters: In the setup menu, verify that the correct motor type and feedback mode are selected as per the Certikin manual.
- Test at fixed frequency: Set the controller to open‑loop (no feedback) mode if available and see if the pump runs normally. This helps confirm a feedback issue.
If the speed sensor is integrated into the motor and is faulty, the complete motor or motor‑drive assembly may need replacement.
