Step-by-Step Repair

  1. Step 1 of 6
    1

    Check the power source

    Make sure the outlet is working by plugging in something else (like a lamp). Check if the power cord is fully plugged in at both ends. For battery-powered devices, make sure the battery is charged and properly seated.

  2. Step 2 of 6

    Look for a reset button

    Many devices have a small reset button (often red or recessed). Check the bottom, back, or side of your leaf blower. Press it firmly. If it clicks, that may have been the problem.

  3. Step 3 of 6
    3

    Check the circuit breaker or fuse

    Go to your electrical panel and check if any breakers have tripped (they'll be in a middle position). Flip any tripped breakers fully off, then back on. For plug-in fuses, check if they need replacement.

  4. Step 4 of 6

    Try a full power cycle

    Unplug the device completely. Wait 2-3 minutes. While unplugged, press and hold the power button for 30 seconds (this drains residual power). Plug it back in and try again.

  5. Step 5 of 6

    Inspect the power cord and connections

    Look for frayed wires, bent prongs, loose connections, or burn marks on the plug. A damaged power cord is a common and inexpensive fix ($10-$20 for most replacement cords).

  6. Step 6 of 6

    Test with a different outlet or power source

    Plug the device into a completely different outlet, preferably on a different circuit in your home. If it works on a different outlet, the problem is with your home's electrical, not the device.

If That Didn't Work

  • Old fuel (gas models) is the most common starting issue — drain and replace.
  • The spark plug may be fouled or worn out.
  • The air filter may be clogged with dust and debris.

When to Call a Professional

If basic maintenance doesn't fix a gas blower, the carburetor may need cleaning or adjustment ($40-$80 at a shop). For battery models, if the motor or controller has failed, replacement is usually more cost-effective. A new leaf blower costs $100-$300.
