Are you looking to replace the ignition coil on your lawn mower but not sure if it’s interchangeable with other models? This is a common question for DIYers, so let’s break down what’s involved with replacing an ignition coil and whether or not you can use one from another model.
What is an Ignition Coil?
An ignition coil is a type of transformer used to convert low-voltage energy from your battery into the high-voltage energy needed to ignite the fuel in your engine.
It consists of two coils of wire wrapped around an iron core, and when the current passes through them, they create an electromagnetic field that produces the voltage required to spark the fuel in the combustion chamber.
Are Ignition Coils Interchangeable?
It is important to understand whether or not lawn mower ignition coils are interchangeable when dealing with mower repair. That said, the answer is somewhat complicated.
While some larger mowers may not be able to use parts from other makes and models, many of the small engine brands have standardized coil systems that can be interchanged between different types of ignitions.
Although compatibility across all brands cannot be guaranteed, a qualified technician should be able to confirm the interchangeability of two ignition coils before any work is completed.
Ultimately, it is best to check with both the manufacturer and a knowledgeable individual before attempting a DIY repair.
What Happens if You Use the Wrong Ignition Coil in Lawnmower?
If you use the wrong ignition coil in your lawnmower, it can lead to serious engine damage and decreased overall performance. The ignition coil is a critical component of your engine that produces, stores, and regulates electric charges essential for powering up the spark plug which, in turn, ignites the air and fuel mixture in the combustion chamber.
If the wrong ignition coil is used, it won’t be compatible with your engine’s particular configuration and so cause disruption and misfiring, leading to excessive wear on some parts of your lawnmower’s engine.
In addition to the damage done by misfiring, using an incompatible ignition coil may also result in insufficient or no spark at all causing non-combustion of air-fuel mix and ultimately damaging the valves too.
Therefore, it’s important to always use the right ignition coil for your specific model of a lawnmower or you could be looking at costly repairs or even having to replace your entire engine down the line.
How Do I Find My Ignition Coil Model?
To find your ignition coil model number, start by removing any covers or pieces of plastic shielding that may be covering it up. Then, look for a small metal label attached to the side of the unit, this should include information such as size and voltage requirements.
Knowing this information can help you find an appropriate replacement at your local hardware store or online retailer.
What is the Life Expectancy of an Ignition Coil?
The life expectancy of an ignition coil in a lawnmower can vary significantly depending on factors such as operating environment, frequency and quality of maintenance, and the type of coil used.
Many factors that impact an engine’s overall performance can also affect the lifespan of the ignition coil. For example, if the filter is not changed regularly it increases strain on the engine and speeds up ignition coil degradation.
Regular preventive maintenance is key in extending ignition coils’ life. Generally speaking, the average lawnmower owner can expect to get anywhere between 3-5 years out of their ignition coil depending on the above-mentioned contributing variables.
To ensure you’re getting the most longevity possible out of your mowers’ ignition system, always double-check instruction manual recommendations regarding service guidelines and maintenance schedules.
While most lawn mower ignition coils are interchangeable between models, it’s best to match your replacement as closely as possible with your existing unit.
To find out which model fits yours, look for a small metal label attached to its side which should include size and voltage requirements. With this information in hand, you should be able to find a suitable replacement at any local hardware store or online retailer.
