Is your trusty Echo PB-250LN leaf blower suddenly sputtering and refusing to start? You’re not alone. Ignition coil problems are a common issue with this popular model, causing frustration for countless users.
Particularly, Echo PB-250LN ignition coil problems such as sudden shutoff, and no spark, are most widespread among users. The number of victims is increasing day by day.
So, whether you’re a seasoned outdoor enthusiast or just dipping your toes into lawn maintenance, understanding these issues is crucial for keeping your equipment running smoothly. So, settle in, and let’s have a look at some ignition coil issues that have been plaguing Echo PB-250LN users everywhere.
Echo PB-250LN Ignition Coil Problems
The Echo PB-250LN can have ignition coil problems due to dirt, heat, moisture, and maintenance neglect. Understanding root causes is key for prevention and maintenance.
Shutting Down While Running Full Throttle
A significant number of Echo PB250LN owners reported the leaf blower shutting down at full throttle and being unable to start since. The spark plug was replaced and properly gapped, but the issue persists.
Now, many experts might suspect whether there is any issue with the compression or fuel. But in the case of this issue, the scenario wasn’t related to this kind of problem as both compression and fuel levels were good in the victim’s machines.
Upon further investigation, it was discovered that the problem lay within the ignition system of the Echo PB250LN leaf blowers. Specifically, a faulty ignition coil seemed to be at fault for causing the shutdowns and difficulty in starting.
Several users who experienced this issue sought professional help and had their ignition coils replaced. Once replaced, they found that their leaf blowers were functioning properly again without any signs of shutting down or starting issues.
However, it should be noted that not all owners may require an entire replacement of the ignition coil. Some have reported success by simply cleaning and adjusting certain components within the ignition system.
No Spark
The Echo PB-250LN leaf blower has been the subject of complaints from owners experiencing a no-spark issue, which has been linked to a faulty ignition coil. This issue has surfaced in various forums and reviews, indicating that it is not an isolated incident.
The bad ignition coil has been identified as the root cause of the problem, leading to difficulties in starting or running the leaf blower. Both professional landscapers and homeowners alike have reported encountering this issue with their Echo PB-250LN units.
The ignition coil serves a crucial role in providing the necessary spark for igniting the air-fuel mixture within the engine. When it malfunctions, the engine’s ability to start and operate efficiently is compromised. Fortunately, replacement ignition coils are available as aftermarket parts for those encountering this issue with their Echo PB-250LN leaf blowers.
How to Test Bad Ignition Coil in Echo PB-250LN Blower
Testing the ignition coil of a leaf blower can be approached in various ways. Some experienced mechanics prefer the method of disconnecting the spark plug wire and grounding it against a metal chassis while cranking the engine. If a spark is produced, then the ignition coil is not likely to be the issue.
However, this approach is not advisable for non-professionals due to its complexity and the potential risk of electric shock, fire, and other hazards. For home users, a safer alternative involves utilizing an ignition coil tester, which can be easily obtained. The suggested methods for testing the leaf blower’s ignition coil are as follows:
Spark Test
To begin the process of diagnosing potential issues with the ignition coil of your Echo PB-250LN leaf blower, start by carefully opening the motor cover. Utilize a screwdriver to remove the cover, and ensure that you label or photograph the parts as you disconnect them to aid in reassembly later.
After removing the cowling, proceed to detach the spark plug and mark the metal chassis of the engine. It’s important to disconnect the cable from the spark plug for safety reasons.
The next step involves testing the ignition coil, which requires focused attention and caution. Hold onto the insulated part of the wire while positioning it against the chassis, then attempt to start the engine and observe whether any sparks are produced when they come into contact. If you notice flashes of light, this indicates that the coil is functioning properly.
Resistance Test
One of the simplest ways to check the ignition coil in a leaf blower is to hold the spark plug against the chassis, but this method is not the safest or most convenient. It’s important to note that small sparks may not be visible, and their absence doesn’t necessarily indicate a faulty coil.
Tiny sparks may be present even when the ignition coil isn’t functioning properly. Due to these concerns, home users typically prefer a different method that is more efficient and safer.
This alternative technique involves disconnecting the ignition module and using an ohmmeter or a digital multimeter to test the coil. The multimeter is a standard tool for measuring resistance and testing for electric current in various items. Here is how to get the job done:
Step 1:
When dealing with the ignition coil of an Echo PB-250LN leaf blower, it is essential to have a good understanding of the engine and motor type. It is important to know the correct resistance reading for the multimeter specific to your leaf blower model. This information can be obtained by contacting your retailer or researching online.
Step 2:
Using a screwdriver, carefully loosen and remove all screws and bolts from the outer casing (cowling) of the motor, then set the cover aside. Once the cowling is removed, you should be able to locate the flywheel and ignition coil, depending on your leaf blower model.
Step 3:
At this point, disconnect the cable running to the spark plug from the plug using caution. Use pliers to loosen and remove bolts holding the ignition coil in place, ensuring that all tiny screws around that area are unscrewed as well.
Step 4:
Once everything is safely removed, detach the ignition coil from its bracket. Connect a multimeter by attaching its red end to the spark plug and its black end to the ignition coil using their tooth-like structures for easier connection. Then place the ignition coil on a flat surface.
Step 5:
Observe the ohmmeter’s display when using an analog model to monitor the leaf’s movements (the pointer). If a digital model is being used, the display will show numeric values instead of previously set ones. Record any readings obtained and proceed to interpret their significance.
A reading of one on the ohmmeter indicates complete resistance, implying a lack of connection and a non-functioning ignition coil. Conversely, a reading of zero signifies no resistance at all, indicating proper functioning of the ignition coil – good news for addressing Echo PB-250LN ignition coil problems.
Final Words
Ignition coil problems experienced by some users of the Echo PB-250LN highlight the importance of regular maintenance and quality control in outdoor power equipment.
It is essential for owners and operators of the Echo PB-250LN to be aware of these issues and to take proactive measures and inspections to mitigate potential problems.
