Abnormal Current Error
Error Code 21 on your QuietKat electric bike indicates a problem with the current flow within the motor or controller system. It typically suggests that there is a deviation from the expected current levels, which can impact the bike's performance and safety.
Troubleshooting Steps for Error Code 21
1. Safety First:
- Ensure your bike is parked safely and turned off before attempting any troubleshooting.
2. Check for Obstructions:
- Inspect the bike's drivetrain, wheel, and chain for any obstructions or debris that could impede the movement of the motor. Clear any foreign objects that you find.
3. Verify Motor Connections:
- Examine the motor's electrical connections for loose or damaged wires. Disconnect and reconnect any connections between the motor, controller, communication harness, and display.
4. Inspect Controller Wiring:
- Inspect the wiring and connectors leading to the controller. Look for loose or frayed wires, and secure any loose connections. If you find frayed or damaged wires, contact QuietKat support immediately.
5. Check for Overheating:
- Overheating can cause abnormal current readings. Ensure that the motor and controller are adequately cooled during operation and not exposed to excessive heat.
6. Contact QuietKat Support:
- If the error persists after checking all connections, it will likely require a professional technician's evaluation. Contact QuietKat's customer support for further guidance and to place an order for any necessary replacement parts. If you are still within your warranty period, or have the Extend warranty, this will be covered. If you are outside of your warranty period, we will send you a quote for the replacement part(s).
