Every manufacturers’ table saw can face it. A Ryobi table saw blade not spinning is a well-known issue. Issues with Steel city table saw are also pretty common.

But, what are the reasons that your table saw blade is not spinning? I have identified 5 common reasons behind it.

Let’s diagnose the issue!

Reason 1 of 5: Worn Motor Brush

A motor brush is a key element that supplies electricity to the blade. By this, you now know how crucial this component is.

However, it can be the reason why your table saw blade is unable to spin. A worn motor brush is unable to supply electricity to the blade. Hence, it fails to spin.

Reasons 2 of 5: Faulty Electrical Connection

A 2 hp table saw requires about 1800 wattage of electricity to operate. So, you get the point that the blade won’t spin if the electricity supply is inadequate.

A disruption in the supply of electricity can happen due to a faulty electrical connection. The scenario can occur after years of using a table saw. However, a fairly new table saw can face a similar issue.

Reason 3 of 5: Swollen Capacitor

A capacitor provides additional power when starting a table saw. It stores electrostatic power for the table saw blade to spin correctly.

A swollen capacitor cannot draw extra power for the blade. Hence, your table saw blade may not be spinning.

Reason 4 of 5: Loose Grip on the Device

Having a tight grip on the blade with a table saw is important. The blade won’t spin or slowly spin if the grip is loose.

Most of cases, your blade may not spin at the desired speed. In some cases, however, the table saw blade won’t spin at all.

Reason 5 of 5: Faulty Device

We all know that an electrical device may be faulty. Maybe your table saw is manufactured and shipped as faulty.

If your new table saw blade not spinning then this can be the reason. It’s just a stroke of sheer bad luck. Nevertheless, the case of the device being faulty is very rare.

Lastly, check the electrical outlet with a tester screwdriver. If the electricity supply is unavailable, the tester won’t blink. If that’s the case, fix or change the electrical outlet.

Troubleshoot 3 of 5: Swollen Capacitor

Capacitor is a key element for the blade to spin. If that’s damaged or swollen, the electricity supply won’t be adequate.

The capacitor breaks down after a certain period. Because these aren’t designed to sustain forever as the oxygen is present. As oxygen enters, it creates decomposition, and gas gets produced. Hence, it can get swollen.

Let’s see the possible solution for it.

If you notice the capacitor is swollen, then you have to replace it. The capacitor isn’t as costly as you might think. You can get a new capacitor for very cheap. Take a look at some of our recommended capacitors: 

We’ve tested these capacitors in the most extreme settings and they fared really well. Try them out!
