Why Has My Electric Lawn Mower Stopped Working?

You’re ready to tackle your lawn, but your electric mower refuses to cooperate. The dreaded silence where the hum of the motor should be is enough to make anyone frustrated. You’re not alone! Many homeowners have experienced this dilemma. But don’t panic just yet. This article will guide you through the common culprits behind a stalled electric lawn mower, from simple fixes to potential repairs. We’ll explore troubleshooting steps, safety precautions, and even preventative maintenance tips to keep your mower running smoothly for seasons to come.

Why Your Electric Lawn Mower Might Be Acting Up

Electric lawn mowers, while generally low-maintenance, can face issues due to several factors, including power supply problems, motor malfunctions, or simple user errors. Understanding the possible causes will help you pinpoint the problem and find the solution.

Is It a Power Issue?

1. Check the Power Cord and Outlet

The most obvious culprit is a faulty power connection. A damaged cord, a loose connection, or a malfunctioning outlet can all prevent your mower from working.

How to Troubleshoot:

  • Inspect the Cord: Carefully examine the power cord for any visible signs of damage, such as cuts, fraying, or exposed wires. If you spot any, replace the cord immediately.
  • Test the Outlet: Plug a different appliance into the same outlet to ensure it’s receiving power. If the other appliance works, the outlet is likely fine, and the problem lies with the mower.
  • Check for Loose Connections: Make sure the power cord is securely plugged into the mower and the outlet.

2. Is the Circuit Breaker Tripped?

Electric lawn mowers draw significant power, and if the circuit breaker controlling that outlet is overloaded, it might trip.

How to Check:

  • Locate the Circuit Breaker Box: Find the circuit breaker box in your home.
  • Identify the Breaker: Look for the breaker that controls the outlet where you’re plugging in your mower. You can usually find this information on the breaker panel itself.
  • Reset the Breaker: If the breaker is in the “off” position, gently flip it back to the “on” position.

Motor Mishaps: Could It Be Your Motor?

If the power supply seems fine, the problem might reside in the motor itself.

1. Overheating Motor:

Electric motors are prone to overheating, especially if they’re used for prolonged periods or in hot weather.

How to Identify an Overheated Motor:

  • Feel the Motor: If the motor feels abnormally hot to the touch, it’s likely overheating.
  • Smell the Motor: A burnt or electrical smell can also indicate overheating.

Troubleshooting:

  • Allow the Motor to Cool: If you suspect an overheated motor, unplug the mower immediately and allow it to cool down completely before attempting to use it again.
  • Check for Obstructions: A jammed blade or other obstruction can cause the motor to work harder and overheat.

2. Worn-Out Brushes:

Electric motors rely on carbon brushes to create a current flow. Over time, these brushes wear down, leading to poor electrical contact and reduced power.

How to Identify Worn-Out Brushes:

  • Check the Brushes: If you can access the motor, inspect the carbon brushes for signs of wear. They should be at least half their original length.

Troubleshooting:

  • Replace Worn-Out Brushes: If the brushes are worn down, replacing them is essential. You can find replacement brushes specifically designed for your mower model.

3. Fuses:

Some electric lawn mowers have fuses that protect the motor from overloads. If the fuse is blown, it will need to be replaced.

How to Check and Replace a Fuse:

  • Locate the Fuse: Check the owner’s manual for the fuse location. It’s often found near the motor.
  • Inspect the Fuse: Look for a burnt or broken filament within the fuse.
  • Replace the Fuse: If the fuse is blown, replace it with an identical fuse rated for the correct amperage.

The Blade: Is It Blocking the Motor?

1. Jammed Blade:

A jammed blade can be a common cause for a stalled motor. A piece of debris or a thick patch of grass can become trapped, preventing the blade from rotating.

How to Clear a Jammed Blade:

  • Unplug the Mower: Always unplug the mower before attempting to clear a jammed blade.
  • Remove Obstruction: Carefully remove any debris or grass stuck to the blade. If you’re having trouble, use a pair of pliers or a small tool to dislodge the obstruction.

2. Bent or Damaged Blade:

A bent or damaged blade can put extra stress on the motor, causing it to malfunction or even stop working completely.

How to Identify a Damaged Blade:

  • Inspect the Blade: Carefully examine the blade for any bends, cracks, or other signs of damage.

Troubleshooting:

  • Replace the Blade: If the blade is damaged, it’s crucial to replace it with a new one specifically designed for your mower model.

Other Potential Causes

Beyond the common culprits, other factors could be contributing to your mower’s troubles:

  • Battery Issues (for Cordless Mowers): If you have a cordless electric mower, a depleted or faulty battery could be the reason for its failure.
  • Safety Switch Malfunction: Some mowers have safety switches that prevent them from operating unless they’re in the correct position. A faulty switch could be interfering with the power supply.

Preventative Maintenance: Keep Your Electric Mower Running Smoothly

Regular preventative maintenance can go a long way in ensuring your electric lawn mower’s longevity and performance:

  • Clean the Mower: Regularly clean the underside of the mower to remove grass clippings and debris.
  • Check the Battery (Cordless Mowers): Charge or replace the battery as needed, ensuring it’s in good condition.
  • Lubricate Moving Parts: Apply a light oil or lubricant to the moving parts, such as the blade and bearings, to prevent rust and wear.

When to Call a Professional

If you’ve exhausted all of the troubleshooting steps and your electric mower still isn’t working, it’s time to call a professional. A qualified technician can diagnose the problem and perform necessary repairs. They can also ensure any repairs are done correctly and safely.

Conclusion

While it can be frustrating when your electric lawn mower stops working, understanding the common causes and troubleshooting steps can help you get back to tackling your lawn quickly. Remember to prioritize safety, use the right tools, and consider professional help when needed. With a little care and attention, your electric mower can continue to provide years of reliable service.
