A table saw is an important tool for DIYers. But, we get it when a table saw blade isn’t spinning it’s a critical issue.
So, why is my table saw blade not spinning?
It can happen due to worn motor brushes. You have to change the motor brush. A faulty electrical connection can cause the issue. If those are broken, replace them. Another reason can be swollen capacitor. The blade can be loosely connected to the device. Tightening it may solve the issue.
This is only a fraction of the issue. You need to know more so that you can fix the issue.
So, let’s begin!
5 Reasons Why Table Saw Blade Not Spinning
The table saw blade not spinning is a frustrating issue. However, it is a very common scenario, and many people face it. Unfortunately, you are facing it now. But don’t be too tense. I will guide you to fix the problem.
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.
These are the reasons why your table saw blade may not spin. Don’t worry! We have troubleshot each reason and provided appropriate solutions.
Let’s jump to the next section then!
Troubleshooting Table Saw Blade Not Spinning
You may be thinking about how to fix a table saw blade not spinning? Well, I have got your back.
A table saw can face many issues. For instance, the throat plate of table saw won’t’ flush. Just like that, the issue with the blade not spinning is also common.
A bit of warning before we start! If your table saw has a warranty, then it is advised to contract manufacturers. Because they will provide all the assistance you need and might even replace it.
Yet the issues can easily be fixed on your own! So buckle up and let’s fix the issue!
Troubleshoot 1 of 5: Worn Motor Brush
By now you know the importance of a motor brush. But, how did the motor brush got damaged?
The first reason could be unstable voltage. The motor brush can get burnt for that reason.
Secondly, continuous usage can cause damage to the motor brush.
Lastly, the motor brush naturally got worn. As in, the motor brush was used to its initial time phrase.
Now, let’s fix the issue.
Solution:
If the motor brush is worn, then there’s only one solution to it. You need to replace the motor brush. A motor brush typically costs not more than $20-30.
Troubleshoot 2 of 5: Faulty Electrical Connection
Let’s get this straight. A faulty electrical connection can cause many problems. In your case, this can be a reason.
The electrical cord that you use can be worn. For that reason, the electricity supply gets disrupted.
Another reason can be that the electrical outlet isn’t supplying enough power. As a result, an adequate power supply is unavailable.
Solution:
First and foremost, check the cable connection to the power source. It can be loose and the power supply can be disrupted.
If it didn’t help, check the electrical cords. If they are faulty, you need to replace those.
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.
Solution:
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.
Troubleshoot 4 of 5: Loose Grip on the Device
The blade is attached to the table saw. So, the grip needs to be strong enough for the table saw blade to spin.
Reports claim that the Delta table saw blade not spinning happens for this reason.
So, let’s fix the issue.
Solution:
In case of a loose grip you have to tighten it. The steps to do so are given below.
First, remove the table saw from the electrical outlet.
Secondly, check to see if the blade is flat. When you put it on a flat surface, it should lie flat on the ground.
Thirdly, Tighten the arbor nut and bolts found beneath the tabletop. Check all of the nuts on the tilt and depth adjustments as well.
Lastly, check if the blade has a tight grip or not. If that’s not the case, you have to get a new one.
Troubleshoot 5 of 5: Faulty Device
It is just sheer bad luck if your table saw turns out faulty. As a reason, your blade won’t spin.
Let’s see what you should do in this case.
Solution:
If your table saw has a warranty, contract the manufacturer. In most cases, they will solve the problem. They can even change the device.
However, if you don’t have a warranty, following the previous methods will help.
That’s all regarding troubleshooting the issue. You must follow the table saw woodworking safety procedures. Otherwise, many hazards can occur.
