Controller Replacement

The controller is the brain that drives the motor. A failed controller can cause no power, cutouts, or erratic behavior. Replacing it with the correct unit restores normal operation.

Frequently asked questions

How do I know the controller is the problem and not the motor?

A diagnostic checks for output to the motor and signal faults. No drive with a healthy motor and battery points to the controller.

Does the replacement controller have to match exactly?

It must match your motor's voltage and current rating and use compatible connectors, or it can underperform or fail.
