Troubleshooting Electric Leaf Blowers Troubleshooting Electric Leaf Blowers
Electric leaf blowers are a straightforward piece of equipment that many gardeners prefer to use. If one is not working properly, the problem will be small and probably not difficult to locate. Here's a routine to check your leaf blower from plug to mouth.
1. Owner's Manual
Check the manual for any instructions that might relate to the problem you are experiencing.
2. Power Supply
Make sure there's power in the socket you have the leaf blower plugged into.
3. Plug and Cable
The plug and cable are basic leaf blower parts that can give trouble because of the treatment they receive.
To check the plug (unless it is welded to the cable) you need to take the cover off. Look to see if the terminals inside the plug have come loose. To correct this problem, reconnect the terminals.
To check the cable, examine it inch by inch to make sure it has not been cut or worn, causing a short circuit or no circuit at all.
4. Leaf Blower Terminals
Use a mains tester to check that power is arriving at the terminals in the leaf blower.
5. Impeller or Fan
Unplug the leaf blower and check that the impeller or fan has not been jammed by a stick or other object so that it cannot turn. If the impeller can move, turn it by hand to see if you can hear a grinding noise. If the bearings on the impeller have worn they could lock up when power is applied to the shaft.
6. Electric Motor
Open the inspection hatch for the electric motor and check that the central spindle will turn.
7. Check Again
Plug the leaf blower in again and test it. If it still will not work and if there is power arriving at the leaf blower you now need to check the on/off switch. Unplug the leaf blower and use a circuit tester to ensure that the on/off switch is working properly.
8. Electric Motor
When everything else checks out there are only two possibilities left. The first is that there is a thermal cut out on the leaf blower. The second is that the electric motor is not working.
9. Thermal Cut Out
A thermal cut out will usually reset itself after about 30 minutes, or there will be a reset button on the machine. If there isn’t a reset button and the machine still won’t work, the final possibility is that the electric motor needs new brushes.
Replacing the brushes in the motor will require purchasing some new parts for your electric leaf blower.
