Shark Vacuum Overheating Problem [Easy Solution]

Shark vacuums are an excellent choice for pet owners, especially ones who have large areas of carpet on which their pets love to play. When the vacuum overheats, however, it can make your home unclean and unsafe.

Here are some reasons your Shark vacuum might be overheating and what you can do to fix the issue.

Shark vacuum overheating problem usually occurs when the user has a particularly large amount of household dust on their floors. It is imperative that you empty the dust cup after each use so as to avoid such an occurrence.

Turn off the Shark vacuum and unplug it for at least one hour to let it cool down. Inspect your attachments and remove any debris that got stuck inside. Replace the power cord if the vacuum won’t turn on and cleaning doesn’t work.

Sadly, due to their large size and powerful suction, shark vacuums may overheat. This can sometimes occur when the vacuum is not used correctly or enough time in between uses. If you notice that your vacuum isn’t working as it should, you may be left frustrated. However, this doesn’t have to be the case.

Shark Vacuum Overheating Problem – Troubleshooting And Diagnosis

Vacuums are good at sucking up leaves, dirt, and dust. They’re not so great at staying cool when they’re sucking up too much of those things. When your vacuum motor overheats while you’re using it, there’s only one real solution: stop using it and let it cool down a little before turning it back on again.

If your Shark vacuum overheats, it will be unpleasant for you and your home. When a vacuum overheats, it produces an ugly odor that can stain your curtains and furniture; this is especially true if you have pets in the home.

Worse still, an overheating vacuum can seize up completely — new users may turn the device on and experience a strange howl or faint vibration sound but little or no suction.

When it comes to your Shark vacuum, there are a few things that should never be overlooked: regular cleaning and maintenance. A vacuum isn’t just a machine — it’s an extension of you, and you should treat it as such.

1. Dirt Container Is Full

If your Shark vacuum is overheating, it may be because the dirt container is full. The full dirt container can cause the vacuum to overheat and shut off. To fix this, simply empty the dirt container and continue using the vacuum. Over time, the overheating should stop.

If you notice that your vacuum is leaving dirt behind after just a few passes over the same spot, it’s likely that your dirt container is full. This can cause your vacuum to overheat, so it’s important to empty the container regularly.

2. Clogged Filter

If your Shark vacuum has an overheating issue, it is most likely due to a clogged filter. The filter is responsible for trapping dirt and debris, and over time it can become clogged.

This can cause the vacuum to overheat, as the motor has to work harder to suck up the dirt and debris. A dirty filter means your blower blower has to work harder to circulate air and will reduce your furnace’s efficiency.

To fix this, you’ll need to clean or replace the filter.

To clean the filter, simply remove it from the vacuum and rinse it with warm water. Allow the filter to dry completely before putting it back in the vacuum.

Replace the filter every few months as a preventive measure and more frequently during peak use.

3. Clogged Vacuum Attachments

If you find your vacuum overheating, chances are it is due to clogged vacuum attachments. Overheating is common with vacuums that are used frequently and for long periods of time. The best way to prevent your vacuum from overheating is to clean the attachments regularly.

To fix this problem, unplug the vacuum cleaner and remove the attachments. Clean the attachments with a soft brush or a vacuum attachment brush. Once the attachments are clean, reattach them to the vacuum cleaner and plug it in.

4. Electricity Problem

The first thing that you want to do is to check for any loose cords, especially if you have pets in the house.

Pets can easily chew on cords and cause them to become frayed or disconnected. If you have any loose cords, you want to make sure that you replace them immediately.

The next thing that you want to check is the outlet that you are using to power your vacuum. If the outlet is not working properly, then it can cause your vacuum to overheat.

You want to make sure that the outlet is turned on and that it is not overloaded. Once you have checked the outlet and the cords, you want to check the vacuum itself.

If you find that there is something wrong with the vacuum, you want to make sure that you turn it off and unplug it.

Once you have done this, you want to open up the vacuum and look at the motor.

5. Impermeable HEPA filter

A HEPA filter is designed to trap very small particles, and if it becomes clogged, it can restrict air flow and cause the vacuum to overheat.

If the vacuum is overheating, it is likely that the HEPA filter is not allowing enough air to flow through it. This can happen if the filter is not properly seated, or if it is clogged with debris. 

To fix this, first make sure that the filter is properly seated. If it is not, then remove it and clean it off. If the filter is clogged, then replace it with a new one.

To clean a HEPA filter, first remove it from the vacuum. Next, use a soft brush to gently remove any dirt or debris that is on the surface of the filter. Finally, rinse the filter with warm water and allow it to air dry completely before putting it back in the vacuum.

6. Damaged Motor

The Shark vacuum may overheat if the motor circuit is damaged. This can happen if the vacuum is used for an extended period of time or if the vacuum is used to clean a large area.

If the vacuum overheats, the motor will shut off and the vacuum will need to be cooled down before it can be used again.

The best way to prevent the vacuum from overheating is to make sure that the motor circuit is not damaged.

Check the motor to see if it is burned out or if the windings are damaged. You may need to replace the motor.

Final Thoughts

If your Shark vacuum starts to overheat, turn it off immediately and unplug it from the power outlet. Let it cool down for at least 30 minutes before you start using it again.

As you can see, this problem can stem from a number of different sources. However, the most likely culprit is either a faulty roller brush, a blockage in the vacuum hose, or an issue with the vacuum’s airflow.

If you have troubleshot the problem and still can’t seem to fix it, we recommend that you take your vacuum to a qualified technician or the place of purchase for further assistance.
