1. Refusing to Start

Most of the time, the main reason why the Ryobi 40V blower does not start is the spark plug. It may have become damaged over time.

Also, the insulator can become torn. Another common reason for this behavior is a burnt electrode.

If you do not replace these faulty parts, the Ryobi 40V leaf blower will not start. The motor may spin for a while. But it won’t be able to work properly.

The Fix

To fix the issue, you have to replace the spark plug. But first, you should examine it thoroughly. Use a spark plug tester to inspect it. The Lisle Spark Tester from Amazon is a great product for this procedure.

If there are no signs of sparks while you press the turn-on button, that means that the spark plug is damaged. You can easily buy a new one from the store and replace the old one.

2. Stops Working Suddenly  

The fuel filter or air filter might make the Ryobi 40V Blower stop suddenly while operating.

Mainly, a jammed fuel filter or air filter is the reason for this issue. The fuel filter may become jammed by evaporated fuel.

If the air filter gets jammed, the motor will not get enough power to spin the blades. As a result, the blower may stop abruptly.

The Fix

You have to ensure that these two parts (The air filter and the fuel filter) are clean. The fuel filter will get clogged if you leave old oil inside. So, if you do not use it, make sure that there is no leftover oil inside.

If it has clogged, clean the area with a cleaning product.

For the air filter, you should clean it once or twice every month. The cleaning depends on the amount of workload on the blower.

3. Flickering Lights

The charger of the Ryobi 40V Blower may start to flash. It will alternate between green and red lights indicating that there is a fault.

There might be a couple of reasons for this issue. The battery may have become discharged beyond the limit. This is called sleep mode.

Another reason is the fluctuating temperature of the battery. If the temperature is very high or low, the charger may flash. If the battery terminals are dirty and the connections are loose, the lights may also flicker.

The Fix

To fix the sleeping mode issue, you should charge the battery at frequent intervals. Charge the battery until the lights start to flicker and recharge the battery after a while again.

Also, you should always maintain a proper temperature for the battery. Never leave it at freezing temperature or let it become extremely hot.

You should also make sure that the terminals of the battery are clean and the connections are firm.

4. Faulty Battery

This is a very common issue with the Ryobi 40V blowers that many customers overlook. But it is an easy procedure to examine if the battery has become faulty or not.

If it has malfunctioned, you will notice that the battery has stopped taking power.

The Fix

You have to inspect the battery with another charger to determine if it is in working condition or not.

You can either take the battery to a nearby electronics shop or a repair shop. They can easily test it out for you.

If the battery is damaged, you can send it to Ryobi for the 3-year warranty service.

5. Low Power

The power of the Ryobi 40V blower may become weak. As a result, the blower won’t be able to suck in the leaves properly.

The main reason for this is a low-speed setting or a full vacuum bag.

The Fix

Inspect your speed meter and adjust it properly according to your need.

Also, make sure that you empty the vacuum bag when it is full. If the blower still does not work properly after doing these, check for clogs.

6. Coupling Issue

The coupling of the Ryobi 40V blower is known to fail frequently. This happens when the shaft starts to slip on the coupling.

A replacement for the coupling is also very rare to find.

The Fix

You have to replace the coupling with a custom-made one. Open up the blower with a screwdriver and take out the old fuel rubber line.

Now replace the cracked or slipped coupling. You can look at this video for a visual demonstration.
