Imagine this: It’s a sunny Saturday morning, and you’re ready to give your lawn a much-needed trim. You’ve got your trusty lawn mower by your side, and you’re all set to conquer the overgrown grass. But alas! The mower just won’t start. What could be the problem? One possible culprit is a bad ignition coil.
In this article, we’ll dive into the world of lawn mower maintenance, focusing on the telltale signs of a failing ignition coil. With a conversational tone and real-life examples, we’ll help you become an expert at spotting bad ignition coil symptoms in lawn mowers.
The Heart of the Problem: What is an Ignition Coil?
Before we get into the nitty-gritty of bad ignition coil symptoms, let’s take a quick look at what an ignition coil is and why it’s so important for your lawn mower’s performance.
The ignition coil is a small but essential component that generates high voltage energy to ignite the fuel-air mixture in the engine’s combustion chamber. In other words, it’s the spark plug’s best friend. When the ignition coil malfunctions, your lawn mower’s engine may struggle to start, run inefficiently, or stall unexpectedly.
Warning Signs of a Bad Ignition Coil in Lawn Mowers
Now that you know what an ignition coil is and how crucial it is for your mower’s performance, let’s explore the most common symptoms of a failing ignition coil:
1. Trouble Starting the Engine
Picture this: You pull the starter rope, and nothing happens. You try again and again, but your lawn mower refuses to cooperate. This frustrating scenario is a classic symptom of a bad ignition coil.
When the ignition coil fails, it can’t generate the spark needed to ignite the fuel-air mixture in the engine. As a result, your lawn mower may struggle to start or not start at all.
2. Misfiring or Stalling
A misfiring engine is another common symptom of a bad ignition coil. You might be happily mowing your lawn when, out of the blue, your mower’s engine starts to sputter or stall. This can be due to a weak or inconsistent spark generated by a failing ignition coil.
3. Power Loss and Reduced Engine Efficiency
When a lawn mower’s ignition coil begins to fail, it may not generate a strong enough spark to ignite the fuel-air mixture properly. This can lead to incomplete combustion, causing the engine to lose power and operate less efficiently.
As you push your mower around the yard, you might notice that it’s struggling to cut through the grass, or it feels sluggish and underpowered. If you’re experiencing these symptoms, a bad ignition coil could be the root cause.
4. Erratic Engine Performance
Does your lawn mower’s engine performance feel like a roller coaster ride? If your mower’s engine performance fluctuates wildly, with moments of smooth operation followed by bouts of stalling or misfiring, you might be dealing with a bad ignition coil.
A failing ignition coil can cause sporadic electrical issues, leading to unpredictable engine performance. This can make mowing your lawn a frustrating and time-consuming experience.

Frequently Asked Questions (FAQ)
How can I test the ignition coil on my lawn mower?
To test the ignition coil, you can use a multimeter to check the primary and secondary coil resistance. First, disconnect the spark plug wire and set the multimeter to the ohms setting. Then, touch the multimeter probes to the primary and secondary terminals of the ignition coil. Compare the readings with the manufacturer’s recommended resistance values. If the readings are out of range, the ignition coil may be faulty and needs replacement.
How often should I replace the ignition coil on my lawn mower?
The frequency of replacing your lawn mower’s ignition coil depends on the make and model, as well as the usage. As a general rule, you should inspect the ignition coil at least once a year or every 100 hours of operation. If you notice any of the bad ignition coil symptoms we’ve discussed in this article, it’s time to replace the coil.
Can I replace the ignition coil on my lawn mower myself?
Yes, replacing the ignition coil on a lawn mower is a relatively simple task that most homeowners can handle with basic tools and some patience. Before attempting the repair, consult your lawn mower’s owner’s manual for the proper procedure and always follow safety precautions.
How much does it cost to replace an ignition coil on a lawn mower?
The cost of replacing an ignition coil on a lawn mower can vary depending on the make and model. Generally, ignition coils range in price from $20 to $60. If you choose to replace the coil yourself, you’ll save on labor costs. However, if you prefer to have a professional handle the repair, labor costs can range from $50 to $100.
Can a faulty ignition coil damage other parts of my lawn mower?
Yes, a faulty ignition coil can cause damage to other components of your lawn mower if left unaddressed. A failing coil can lead to an overworked engine, excessive fuel consumption, and damage to the spark plug or other electrical components. It’s essential to address any bad ignition coil symptoms as soon as possible to prevent further damage.
In Conclusion: Be Vigilant and Maintain Your Lawn Mower
