Shark vacuums are a great addition to your cleaning equipment because they are robust and long-lasting.
However, just like any other electrical equipment, the vacuum is bound to run into complications here and there.
One of the most common problems reported by Shark vacuum consumers is constant overheating. Of course, the aforementioned is a non-issue if you have been vacuuming for a prolonged period.
But if the problem persists despite you giving the equipment a rest after every 30 minutes of use, then read on!

How to fix a Shark vacuum cleaner that overheating
When a Shark vacuum cleaner is overheating, the thermostat kicks in, prompting the vacuum to power off.
This can be quite inconvenient, but not to worry, as you can quickly identify and rectify the problem.
1. Clogs in the hose
Considering that the primary function of a vacuum is collecting dirt (both big and small), chances are the dirt will eventually clog the wand, hose, or other parts.
To confirm if this is the issue you are dealing with, detach the hose and place your hand on the outlet to check if the suction is good.
If it’s not, insert a wire or thin stick inside the hose and try to fish out any debris causing the blockage.
Additionally, perform the above procedure on all the other attachments for maximum results.
2. Dirty HEPA filter
Most Shark vacuums are fitted with a HEPA filter, which is efficient at filtering out dirt. However, the filter will clog with dirt and hair after use affecting its permeability over time.
If it clogs, the vacuum overheats since the airflow will be heavily restricted.
Unplug the vacuum and open it to check whether the filter is clogged. Confirm whether your vacuum comes with a washable disposable filter from the user manual or the internet.
Assuming it comes with a washable filter, clean it by running it through soapy water followed by clean water before letting it air dry for approximately 24 hours.
On the other hand, if your filter is disposable, visit your nearest convenience store and purchase one similar to the one you just removed.
3. The dirtbag is full
It’s standard maintenance procedure to empty your vacuum’s dirtbag occasionally. Doing so will increase the vacuum’s life span while ensuring maximum performance.
With that said, the vacuum overheats whenever the dirtbag fills up due to restricted airflow. This is because the motor is still generating suction power, yet the hose cannot pick up any dirt; therefore, the warm air is left circulating in the vacuum.
Unplug the vacuum and detach the dirt container. If it is full, empty it and secure the container base.
4. Power issues
If none of the above solves your issue, maybe the problem lies with your power outlet. First, try changing the outlet and see if the problem persists.
Alternatively, you could try using another appliance on the same outlet and see if it works as it should. If other devices work fine, then there is an internal electrical issue.
Ensure you unplug the vacuum and then pry it open to expose the cord’s wiring. Confirm that there are no broken/burnt wires or broken connections. Assuming everything looks perfect, then you have a bigger problem on your hands.
The issue may lie with the motor, therefore, requiring professional help.
However, if the vacuum is still under warranty, you can get it fixed at no additional cost from wherever you purchased it.
Alternatively, a certified technician would be able to decipher and resolve the issue.
5. Broken belt
Most Shark vacuums are fitted with a rubber belt that connects the motor and the roller brush.
Unfortunately, the belt wears off over time due to constant use. You have to replace it.
Whenever this happens, the lack of resistance on the motor causes it to rev up excessively hence overheating. In this case, you will need to replace the belt with a new one.
Alternatively, it could be that the belt is being obstructed by debris that managed to pass through the filter. To solve your issue, clear out the obstruction and wipe down the rest of the vacuum.
