Why Does My Electric Leaf Blower Keep Shutting Off?

The best tool for keeping your yard clean is an electric leaf blower, but when it abruptly stops working consistently, it may be bothersome. Understanding the root causes of this frequent problem will help you to maintain the leaf blower.

There are several potential causes of this problem, including overheating, clogged air filters, insufficient voltage, defective switches or wiring, and battery problems.

In this post, the many causes of an electric leaf blower frequently switching off will be discussed, along with solutions.

Why Does the Electric Leaf Blower Keep Shutting Off?

The electric leaf blower may continue to shut off for a variety of reasons, including overworking the motor with too much particles, which is a safety feature designed to prevent damage.

Another cause could be a clogged air filter, which causes the engine to work harder and eventually shut down. A lack of power or an electrical issue, such as a frayed cord or a faulty switch, can also cause the leaf blower to shut down.

It’s also possible that the leaf blower has a thermal cutoff switch that activates when the motor temperature rises too high, shutting down the machine until it cools down.

8 Reasons That an Electric Leaf Blower Is Having Trouble Staying On (Easy Fixes Included)

Here are some symptoms that will signify that the electric leaf blower has a malfunction. The fixes are of each of these symptoms are included.

1. Dirty Air Filter

the blower may have less power and blow air at a slower rate, if the air filter is filthy and inhibits airflow.

Additionally, the engine may surge or operate erratically due to dirty air filter.

The Fix

The air filter has to be washed with soap and water after being removed from the blower.

Before reinstalling it, let it entirely air dry.

The air filter has to be replaced if it is seriously blocked or damaged.

2. Low Fuel Level

If the fuel level is low, it’s possible that the engine won’t receive enough fuel and may shut off at any moment.

The Fix

Pour the recommended fuel and oil combination into the fuel tank.

Before turning on the blower, always ensure that you check the fuel level.

3. Spark Plug Issue                                         

A spark plug with a buildup of carbon deposits may provide a weak spark that is insufficient to ignite the engine’s fuel and air combination.

The spark plug’s malfunction might prevent it from lighting the mixture in the engine. The engine may shut down as a result of this or fail to start at all.

The Fix

Remove the spark plug, locate it near the top of the engine and use a spark plug wrench to unscrew it.

Check for signs of wear or deterioration, such as cracks, fractures, or a buildup of carbon deposits. Replace the spark plug if it is cracked or damaged.

Install the new spark plug by manually putting it into the engine and securing it with a spark plug wrench.

4. Malfunctioning Carburetor

The delivery of the air or fuel combination to the engine is managed by the carburetor.

The engine may run lean (too much air, not enough fuel) or rich (too much fuel, not enough air) if the carburetor isn’t functioning properly, which might reduce power, cause sluggish operation, or even cause the engine to shut off.

The Fix

Remove the carburetor from the engine, disassemble it, and use carburetor cleaner to clean it of any dirt.

You might need to replace the carburetor if cleaning it does not fix the problem.

5. Blocked Fuel Line

The flow of fuel to the engine might be hampered with time by the fuel line being kinked or blocked with debris. The engine may shut off if the fuel line becomes kinked or obstructed.

Over time, the fuel line may develop cracks or leaks that enable fuel to escape and prevent it from reaching the engine.

The Fix

Replace the fuel line if it is obstructed, kinked, cracked, or leaking. To stop fuel from spilling out, tighten any loose connections.

Use new fuel if the fuel has been sitting for a while to prevent obstructions in the fuel tank, fuel line, or carburetor.

6. Ignition System Failure

Since the ignition coil is in charge of producing the significant voltage needed to ignite the fuel. The engine may shut off if the ignition coil fails and is unable to provide adequate voltage.

The Fix

Examine every component of the ignition system to identify the root of the problem.

Tighten the connectors or reconnect the wires if the wiring is exposed or disconnected. The ignition coil should also be changed if it is defective.

7. Loose Exhaust Port

The exhaust gasket secures the exhaust port’s attachment to the engine. An air leak from a broken or missing gasket can lower engine performance or even cause the engine to shut off.

Additionally, a loose or broken exhaust port may result in an air leak, which may lower engine performance.

The Fix

Clear any dirt from the exhaust port using a tiny instrument like a wire brush or a pipe cleaner.

Install a new gasket in its place if the old one is damaged or gone. Also Restore or replace the exhaust port if it’s broken or loosened.

8. Overloading

The thermal cut-off switch can be tripped by overloading the electric leaf blower engine above its rated power capability, increasing the current demand, or by overheating the motor and activating the thermal protection.

The Fix

The leaf blower should be unplugged and given at least 10 to 15 minutes to cool. Make sure the leaf blower is receiving steady and sufficient voltage by checking the power supply.

Check the vents for air intake and exhaust for obstructions or limits. The airflow may be improved and the strain on the motor reduced by removing any obstructions.

Can an Electric Leaf Blower Shut Off While Using an Extension Cord?

Yes, the leaf blower may shut off randomly if you use an extension cord. If the extension cable is too long, too thin the power may decrease and as a result, the leaf blower will have trouble staying on.

Also, if the extension cord has a faulty insulation, utilizing it with an electric leaf blower may cause it to shut off. If not needed, you should not use an extension cord with the leaf blower.

It is advised to use an extension cable that is heavy-duty and rated for the voltage and amperage of the blower rather than one that is longer than necessary.
