I was using the vacuum cleaner to clean my living room when it suddenly stopped working. I was worried about why this happened.

After checking a few things, I realized it’s a common issue with vacuum cleaners. In order to prevent similar occurrences in the future. I decided to research further into these issues.

In this article, I will show you why your vacuum cleaner stopped working suddenly and how you can fix it.

Let’s get started!

Vacuum cleaner stopped working suddenly

You can try these possible ways if your vacuum cleaner is stopped suddenly to fix the issue.

1. Lack of power

If your vacuum cleaner suddenly stops working, it may be because of a loss of power. This could be due to several possibilities, such as a blown fuse or circuit breaker.

You should also determine the cause of the malfunction; it’s important to check specific areas of the vacuum cleaner related to the power supply.

If none of these elements are found to be faulty, then it may be to look into other components that could be responsible.

2. Active thermal cut out

An active thermal cut-out is a safety-designed feature to protect a vacuum cleaner from overheating. 

It works by detecting when the temperature of the motor has exceeded. Then it automatically shuts off the motor to prevent damage.

In this case, the vacuum’s active thermal cut-out was likely triggered due to an internal component malfunction or an external issue such as a blocked airflow.

The malfunction could have caused the motor to overheat, activating the thermal cut-out to prevent further damage.

This safety feature can be reset manually or automatically, depending on the type of vacuum cleaner.

3. Faulty power switch

Sometimes a faulty power switch causes an issue with your vacuum cleaner, which can be fixed by inspecting or fixing the vacuum.

This could cause the components to have no power, and they will not work correctly. You should check the power switch and determine whether it is stuck, broken, or not responding correctly.

If the problem is within the switch, replacing it with a new one will be the best solution. The switch replacement will cost you about $5-6

It is also essential to ensure that all of the power cables are correctly connected and that there are no loose connections.

4. Empty dirtbag

A full dirtbag is another common cause for your vacuum to stop working; in order to solve the vacuum, it may need to be emptied.

If it is full, the vacuum cleaner will not be able to suck up more dirt. You should empty the dirtbag for optimal performance of the vacuum.

You can empty the bag by removing the bag from the vacuum cleaner and opening it carefully, then empty all of the dirt into a dirtbag.

Also, ensure that you should clean out any remaining debris or dust that may still be inside the bag before putting it back on a vacuum cleaner.

Once you have emptied the dirt bag and then reinserted it into the vacuum cleaner, you should test your vacuum cleaner again to see if this solves the issue.

5. Damaged cord

When your vacuum malfunctions, it’s likely due to a damaged cord. The power cord may have been fraying or damaged.

Which allows electricity to spark and short circuits. It also could cause the motor to shut off immediately.

It can also affect the other components, such as fuses and switches, because of the surge of electricity.

If the cord has been damaged, you should replace or repair it. While you are replacing it, ensure to buy from a certified technician.

You can replace the cord yourself or get in touch with an expert if you are not used to it. 

6. Tangled brush roller

A tangled brush roller may also cause this issue. It is an essential component of the vacuum; it helps to spin the brush quickly to pick up dirt and debris from surfaces.

When the bristles on the brush become knotty or intertwined, they can lead the brush not to spin properly and cause the vacuum to cease functioning.

The problem can be caused by not cleaning the dustbin or using the vacuum too frequently on thick carpets.

You can clean the brush roller by unplugging the vacuum and removing any blockages to access the brush roller. 

Then carefully cut away any tangled pieces of hair or string preventing its rotation.

7. Faulty motor

A faulty motor also causes this issue. A motor could be faulty because of a short circuit, loss of power supply, or suffer from the effects of wear and tear.

Short circuits may occur when the electrical connections between different parts of the motor become overloaded or heat up, creating sparks that can cause damage.

Wear and tear also causes a motor to stop functioning as normal; over time, it will lead to complete failure if not replaced in time.


Why did my vacuum just shut off?

Your vacuum can shut off for various reasons, such as; overheated, obstructions in the airway of the machine causing decreased airflow, or a worn belt.

In order to resolve the vacuum, you can try troubleshooting, such as cleaning filters and checking for clogs.

Why did my vacuum shut off and won’t turn back on?

It’s possible that the vacuum cleaner has overheated and needs time to cool down. It can be because of blockages in the intake or exhaust.

Which prevents air from circulating correctly and causes the motor to overheat. If you can’t find any problems, unplug it, then plug it back in after a few minutes to see if this resolves the issue.

It’s also worth checking the filter and replacing it if necessary since clogged filters reduce suction power and cause motors to strain enough and result in shut off automatically.

How do you know if your vacuum motor is burnt out?

If your vacuum motor is burnt out, you may notice that it has lost suction, does not seem to be working properly, or produces a burning smell.

If you inspect the motor closely and see smoke or signs of scorching or charring on its surface, it is likely that the motor has burned out.

You can also try testing the motor’s power output with an electric meter. If it reads zero volts, then the motor will need to be replaced.

How do you fix an overheated vacuum cleaner?

You can fix an overheated vacuum cleaner by unplugging it and allowing it to cool down. You should check the air filter and exhaust port to ensure they are not clogged with debris.

If necessary, clean out any dust; also, inspect the belt for wear and tear. If it is broken, you should replace it.

Can vacuum cleaners be repaired?

It is possible to repair a vacuum cleaner depending on the type of damage it has sustained. If the vacuum cleaner has a broken belt or clogged filters, it can be replaced easily.

If it’s more complex problems such as motor burnout, it will require much more involved repairs.

Attempting an unauthorized repair could cause further damage, so caution must be exercised when considering this option.

Why does my vacuum stop and start?

Your vacuum may be stopping and starting due to overheating. This can happen when the motor becomes too hot, or the filter or dust bag is blocked.

You can fix this problem by ensuring your vacuum filter is clean, and there are no blockages in the suction hose.
