If the YIKONG YK4107 RC Car 60A Brushed ESC (Part No. 21180) is not working properly, the issue may be related to the battery, wiring, receiver, motor, or the ESC itself. Before replacing the ESC, inspect the power supply and electrical connections to identify the cause.
Common reasons include:
- A discharged or faulty battery
- A loose XT60H-M connector
- Incorrect wiring or poor electrical connections
- A damaged brushed motor
- Receiver or transmitter connection issues
- ESC overheating or thermal protection
- Water damage or internal short circuits
Check each item one by one. If the battery, motor, receiver, and wiring all function normally but the ESC still does not respond, replacing the YIKONG YK4107 RC Car 60A Brushed ESC is recommended to restore reliable vehicle operation.
