Vacuum Cleaner Plug Gets Very Hot: Why and How to Prevent it?

Vacuum cleaners are valuable tools for cleaning up dust and dirt in your home. The problem is that the cord can become very hot during operation. If you touch the cord or plug, you risk burning yourself.

The vacuum cleaner plug is designed to protect against this danger by providing an insulating barrier between the cord and the metal prongs on the plug. However, if the plug becomes too hot, it could melt through the insulation and expose the metal prongs inside. This could cause serious injury.

Luckily, there are a bunch of solutions you can try. But make sure you’re following them properly to avoid any hazards while working.

What if Vacuum cleaner plugs get very hot?

Vacuum cleaner plugs can get very hot, posing a safety hazard. 

Regarding the record of the Consumer Product Safety Commission (CPSC), vacuums with plugs that get too hot can cause injuries by scalding people. The CPSC had received reports of people getting scalded when their vacuum cleaner’s plug became too hot. 

In some cases, the plug caused a severe burn that the individual had to go to the hospital. Vacuum cleaners can become very hot when used, especially if the plug gets stuck in the vacuum cleaner outlet. 

The vacuum cleaner’s motor will continue to run even if it is not sucking anything, which can cause a fire. Consumers should be aware of this and take care when using their vacuum cleaners, especially if they have children. 

Why do vacuum cleaner plugs get very hot?

Vacuum cleaner plugs get very hot for a few reasons. Vacuum cleaner plugs often get very hot, mainly when they’re used for a long time without any breaks.

If the electric motor in the vacuum cleaner is trying to create a lot of suction. This makes the motor heat up, and it also puts a lot of pressure on the plug.

Another common reason is that the electric motor produces a lot of heat as it works to create suction. 

The most common reason is that the wiring in the plug becomes hot from the current flowing through it. Dust and other small particles can lodge in the electrical contacts, heating up as they generate electricity. Also, vacuum cleaner motors are often made from plastic and metal materials that can generate heat when they flex or move.

Another main reason why vacuum cleaner plugs get extremely hot is that there is no airflow. When the motor runs, it generates heat as well as electricity. As the voltage increases, you will also notice current is also increasing. This results in more energy being used up per unit of time.

How to prevent overheating Vacuum cleaner plugs?

How to prevent overheating Vacuum cleaner plugs

Follow these simple steps to ensure your vacuum stays cool to avoid these problems.

Keep an eye on the temperature gauge

Keep your eyes on the temperature of your vacuum. You can find this by looking in the owner’s manual or searching online for a “vacuum temperature gauge.” Once you’ve got that information, you can check if your vacuum cleaner is getting too hot by using it.

Use a cooling fan

If you notice that your vacuum is getting too hot, you may be able to solve the problem simply by turning on a cooling fan. Fans come in different sizes, so choose one to fit your vacuum. Some models come with built-in fans, whereas others require you to buy a separate fan unit.

Replace filters regularly

Filters trap dust and debris before they enter your vacuum. As such, they need to be replaced frequently. To help you remember when to replace them, place a sticker near the filter area of your vacuum. The sticker should say something like “replace after three months” or “change every month.”

Clean out the vents

Over passing time, dirt and debris can build up inside your vacuum. This buildup can block air from flowing through the vent holes, leading to overheating. To remove this buildup, turn off your vacuum, open all doors, and run the brush attachment over the entire surface of the vacuum. Then close all doors and let the vacuum sit for about five minutes. Afterward, wipe down the vents with a damp cloth.

Avoid using harsh chemicals

People seem to think that using chemical sprays and liquids will help their vacuum stay cooler. While this might work for a short time, it could actually damage your vacuum. Instead, try using water to clean your vacuum. It works just as effectively and leaves no harmful residue behind.

Check for leaks

Leaks can occur anywhere in your vacuum. Check around the seams and connections where the two parts meet. Also, look under the floorboard and along the bottom of the base. These areas tend to collect moisture, which can ultimately lead to leaks.

Don’t overload the vacuum

When you’re not using your vacuum, store it upright. Doing so allows the suction power to dissipate naturally. Otherwise, your vacuum will continue to draw in more air than necessary. In addition, don’t fill the vacuum full of items. Leaving room for air helps to reduce the amount of heat generated.

Turn off the vacuum when not in use

When you aren’t using your vacuum, shut it off and put it away. If you leave it plugged into an outlet, it will continue to generate heat.

Use a vacuum bag

A vacuum bag keeps your vacuum cleaner free of lint and hair. Attach the bag to the opening at the top of your vacuum and then pull the handle. Vacuums with bags are easier to maintain because they won’t get clogged as quickly.

Keep your vacuum clean

Regularly clean your vacuum cleaner to avoid spending more money on repairs. Remove the dust and debris from the brushes and other components using a soft bristle brush. When cleaning the filter, make sure to keep it dry. If possible, use a vacuum cleaner without a hose attached. A hose makes it challenging to clean the filter thoroughly.

Change the belt often

Belts wear out over time. If yours is showing signs of wear, change it. Changing your belt early prevents expensive repairs later on.

Get regular maintenance

Regular maintenance will ensure that your vacuum remains working properly. For example, if you notice excessive noise coming from your vacuum, have it checked by a professional.

Follow manufacturer guidelines

Vacuum manufacturers provide information on how to care for their products. Most vacuum cleaners come with a manual or user guide. Read these guides carefully.

Frequently Asked Questions:

Why is the cable on my vacuum cleaner Hot?

The cable that connects the power cord of your vacuum cleaner to the motor can get very hot. This is normal and not a problem, but if you notice it getting too warm or even burning your hand, you should stop using the machine immediately.

Why is the vacuum blowing out really hot air or smoke?

The obvious cause of this problem is that you have a clogged filter. Vacuum cleaners are designed to work with filters, so when they become clogged, they can’t pull dirt through and will overheat. You will find the motor running harder if it’s overheated. If it’s not making any noise, there may be other problems such as a bad belt or broken brush roll. 

Wrap Up

Many people don’t know that vacuum cleaner plugs can overheat and fail, leading to a potentially dangerous situation. Overheating can cause the plug to melt or even catch on fire, leading to severe injury or even death. If you suffer in doubt about the safety of a vacuum cleaner plug, be sure to unplug it and let it cool before using it again. Overheating is the number one cause of fires in homes, and it’s hazardous when it comes to vacuum cleaners. A vacuum cleaner that overheats can start a fire very quickly.
