It’s frustrating when your drone won’t take off—and even more confusing when only one propeller refuses to spin. The good news? It’s usually an easy fix. Whether your drone had a rough landing, picked up some dust, or has a loose connection, there are a few simple things you can check before heading to a repair shop.
In this guide, you’ll learn how to troubleshoot a non-spinning drone propeller, check for damage, clean the motors, fix wiring issues, and even deal with problems after a crash. Most of these fixes take just a few minutes and can get you back in the air fast.

What to Do When a Drone Propeller Won’t Spin
A propeller that’s not spinning is often caused by dirt in the motor, wiring issues, or minor damage. Here’s how to check and fix it:
1. Look for Any Visible Damage
Inspect the propeller, motor, and propeller arm. A bent blade, cracked motor, or damaged arm can all cause the propeller to stop spinning. If anything looks broken, replace it before flying again.
2. Remove Dust and Debris
Small things like sand, hair, or grass can jam the motor. Use a small brush or compressed air to clean around the propeller and motor. Be gentle—avoid pushing debris further inside.
3. Check Motor Wires
Sometimes the problem is as simple as a loose wire. If you can open your drone safely, check the connections around the motor. Look for anything disconnected, frayed, or burnt.
4. Restart or Reset the Drone
Turn off the drone completely, wait a few seconds, and turn it back on. This quick reset can fix minor electronic glitches. If that doesn’t work, try recalibrating your drone using the instructions in the user manual.
Fixing a Drone “Wing” or Propeller Arm
Even though drones don’t have wings like airplanes, their arms and blades serve a similar purpose—helping them fly smoothly. If one of the arms is loose or damaged, here’s what you can do:
Check for Cracks or Breaks: Damaged arms can cause wobbling or prevent proper lift. If cracked, the arm may need to be replaced.
Tighten Loose Screws: Make sure the arms are firmly attached. Use a small screwdriver to tighten any screws.
Balance the Propellers: If one arm or blade is heavier than the rest, your drone might struggle to stay level. Replace warped or chipped blades to restore balance.
If Only One Propeller Isn’t Spinning
When just one propeller stops working, focus on that motor. Try these steps:
Swap the Propeller: Switch the non-working propeller with one that’s working. If the swapped prop spins fine, the original propeller might be faulty or damaged.
Check the Motor: If the new propeller still doesn’t spin, the motor could be bad. Use a voltmeter to see if power is reaching the motor. No power means the motor or wiring needs attention.
Update or Reset Software: In some cases, software glitches can affect motor performance. Try updating your drone’s firmware or performing a factory reset.
Sky Viper Drone Propeller Not Spinning? Here’s a Fix
Sky Viper drones are known for being beginner-friendly, but like any drone, they can run into motor issues.
Charge the Battery Fully: A low battery might not provide enough power to all motors.
Inspect Small Gears: Some Sky Vipers have plastic gears inside. If these get dirty or misaligned, they can stop the blade from turning.
Let the Drone Cool Down: If it overheats, the motor may shut off temporarily. Give it a few minutes, then try again.
After a Crash: Fixing a Drone Motor That Stopped Working
Drone crashes are common, and a motor may stop working afterward. Here’s what to do:
Look for Obvious Damage: If the motor or propeller is cracked or bent, replace it.
Test All Motors: Turn the drone on and test each motor carefully. Motors that don’t respond may need to be swapped out.
Recalibrate the Drone: Crashes can mess with the internal sensors. Follow the manufacturer’s calibration instructions to reset things.
Fixing a Propeller That Just Won’t Spin
If one propeller remains completely dead, try this:
Clean It Thoroughly: Remove dirt, dust, or hair that might be jamming the motor.
Inspect the Motor: If the motor smells burnt or doesn’t spin at all, it’s likely damaged and will need to be replaced.
Check or Replace Wires: Reconnect loose wires or replace damaged ones using a soldering kit or by taking the drone to a repair technician.
FAQs: Drone Propeller & Motor Repair
- Can I fix a crashed drone myself?
Yes, many small fixes—like replacing a propeller or reconnecting a wire—can be done at home with a few basic tools. - Why won’t my drone propeller turn?
It could be from debris, a bad motor, or a wiring problem. Start by cleaning and checking connections. - Can I fly with a broken propeller?
No. Flying with a damaged propeller is unsafe and could crash your drone. Always replace broken blades first. - How do I replace a propeller?
Just unscrew the old one, align the new blade properly, and tighten it securely. Make sure it’s spinning freely before flying.
