Common reasons and solutions to the ‘Shark Vacuum won’t turn on’ problem.

Shark vacuums are feature-rich, making them an excellent choice for many people. However, no one loves a cleaner that has stopped working. The possible reasons for the cleaner not turning on are pretty basic and can be easily fixed. I have listed below some of the common reasons why Shark vacuum won’t turn on.

Loose/Improper power supply connection

Your vacuum cleaner gets power when connecting the plug to your wall or extension socket. While doing this, sometimes, the pin remains loose and does not make a proper connection. As a result, your Shark vacuum cleaner does not get adequate electricity.

To fix this, ensure your plug is correctly connected to the electric socket. If you still see that your Shark vacuum won’t turn on, try moving the wire and plug a little bit. If the problem persists, then it means that your connection is still not proper.

Another thing that you can do is remove the plug and connect it to some other socket just for testing. If that works well, you can understand there was a problem with the previous socket. However, if it is still the same, it is not the socket. There is a problem with the cord or other internal parts of the vacuum cleaner.

To find out whether there are any internal errors, you may need to open your cleaner attachments (in the upcoming segments) and check on the inside. And that brings me to my next common problem: checking the cleaner cable.

Check the cable of the vacuum cleaner.

Disconnect the system from the power supply to ensure your complete safety. Carefully check the vacuum cord of your unit and try to find out whether there are any faults. You may find cuts or cracks on the cable disrupting the electricity flow.

If you find any such issues with your cleaner cord, they need to be changed immediately. On the other hand, if you do not see anything as such, you can move to the next step, resetting the motor thermostat.

Reset Motor Thermostat

When you use a vacuum cleaner, dirt and hair get stuck in the different holes of your cleaner unit. This blocks the holes preventing a proper suction of new dust. But the motor still runs, causing the machine to overheat.

Then, to save the vacuum cleaner circuit, the system turns itself off automatically. Many people consider this an internal fault and complain Shark vacuum stopped working when that is not the case.

To turn it back on, you need to:

  • Unplug the cleaner from the power supply
  • Let the machine cool down
  • Look for and clean off any clogged holes you find
  • Manually reset the thermostat by turning the power switch to the “I-On” position.

Now reconnect the cleaner to the power supply and try turning it on. If the problem persists, check the cable before opening the vacuum unit or call customer support.

It is better not to try opening the entire Shark vacuum cleaner and fix any issue yourself. You may damage the whole cleaner if you do not have extensive knowledge. So it is always better to contact customer support to check it further. 

To prevent overheating, you can regularly clean the brush rolls using a brush and empty the dust cup. You may also need to use a screwdriver to open attachments and clean them thoroughly.


There can be multiple reasons why the Shark vacuum won’t turn on. The steps shown here to determine them are all tried and tested to give positive results. If you follow them, then your problems should get resolved right away.

Also, do not forget to regularly clean the brush rolls of your Shark vacuum cleaner and empty the dust cup. This will ensure prolonged service and prevent the Shark vacuum suction problem.
