Mould King building sets are known for their innovation, engineering, and excitement—especially when it comes to motorized and remote-controlled models. Whether you’re assembling a towering crane, a rugged excavator, or a sleek RC sports car, these dynamic sets bring your bricks to life.
However, just like any advanced system, you might occasionally run into motor or remote control issues. Don’t worry—we’ve got you covered. In this guide, we’ll walk you through the most common Mould King motor and remote control problems, and how to fix them easily.
🔋 1. The Motor Doesn’t Turn On
One of the most frequent issues is a non-responsive motor. Here’s how to check it:
✅ Troubleshooting Steps:
- Check Battery Power: Is your lithium battery box fully charged? Low battery is often the cause of a non-working motor.
- Test the Connection: Ensure the motor cable is securely plugged into the correct port. Try switching ports to see if the issue is isolated.
- Swap the Motor: If possible, connect a different motor to test whether the original motor is defective.
If none of these work, your motor may need replacing. You can find original Mould King spare parts at mouldkinggermany.com/collections/spare-parts.
🎮 2. The Remote Control Isn’t Connecting
Mould King offers both infrared (IR) and 2.4GHz remote controls, as well as Bluetooth app connectivity. If your remote isn’t responding:
✅ Troubleshooting Steps:
- Match Channels Correctly: For IR remotes, make sure the receiver and controller are set to the same channel (A, B, or C).
- Pair the 2.4GHz Remote: Hold the sync button on the remote and power up the model. A blinking LED will confirm successful pairing.
- Replace Remote Batteries: Many users forget to check the AAA batteries inside the controller—don’t overlook this simple fix.
📱 3. Bluetooth App Not Working
Mould King’s official app offers next-level control—but Bluetooth issues may occur.
✅ Troubleshooting Steps:
- Download the Right App: Use the official Mould King Robot App from Google Play or the App Store.
- Turn On Location and Bluetooth: Some phones require location services enabled for Bluetooth to work properly.
- Choose the Correct Model: Select the right MOC or configuration profile to match your build.
💡 Pro Tip: Restart your device and reconnect if pairing fails. You may also need to reset the battery box by holding the power button for 5 seconds.
⚙️ 4. Motorized Movements Are Lagging or Stuttering
This issue is typically caused by low power, motor overload, or too many motors on one battery box.
✅ What to Do:
- Charge the battery box completely.
- Avoid using more than 3–4 motors per box.
- Let the motor cool down—Mould King motors have built-in thermal protection.
