Troubleshooting Guide: My Shark Vacuum Won’t Turn On

Millions of people, like me, choose Shark vacuums because of their reputation for power and innovative features. However, even the most reliable tools can encounter problems. One of the most frustrating issues for users is the Shark vacuum not turning on when needed. In this article, I will address the common causes of the “Shark Vacuum Won’t Turn On” problem and provide step-by-step instructions on correcting the situation with your Shark vacuum.

Reasons Why My Shark Vacuum Won’t Turn On

Vacuum Power Switch (ON/OFF)

Despite being an electrical device, the power switch is important for every electrical appliance, including a shark vacuum. The vacuum may not turn on if the switch is broken or defective.

  • To locate the power switch, unplug the device and visually locate it. 
  • Check the button for any signals of damage or wear. To ensure the switch isn’t jammed, toggle it back and forth a few times if it is in good condition. If the button is damaged, contemplate replacing it.

Power Cord and Outlet

Shark Vacuum Power Cord and Outlet

The first thing you need to do is confirm the power cord is firmly inserted into the socket. 

If the vacuum doesn’t work, plug it back in and try to turn it on. The problem persists, test the device’s functionality using the same outlet as the other device. 

If the second device is working properly, the outlet is not the problem; the problem lies with the power cord attached to your Shark vacuum.

A faulty power outlet is another possible reason for a Shark vacuum not turning on. If the outlet is fixed, your device may need more power to function effectively. 

To determine if the outlet is the problem, insert another item, such as a light or a phone charger, into the same outlet and check for proper operation. This helps you determine if the outlet is the source of the problem.

If the additional device fails to work, the outlet is likely causing the problem. In such cases, either try plugging the vacuum into a different outlet or ask an electrician to repair the faulty one.

Damaged Power Plug/Wires

The proper way to unplug the vacuum from the wall is to pull the plug, not the power cord. Frequent pulling, especially between the plug and the cord, can damage the power cord.

Ensure the wall outlet and electrical breaker/fuse are working properly, then check the power cord for any signs of fraying. If the vacuum cleaner is no longer under warranty, you can take it apart and use an electrical voltmeter to test the power cord.

Evaluate each wire’s impedance (electrical resistance) in the power cord. Also, check the vacuum’s internal switch; It may bloom.

Note: Disassembling the cleaner during the warranty period voids the warranty.

Clogged Filters

The Shark vacuum filter plays an important role in ensuring that the machine works efficiently and has a long lifespan. If the filters are dirty, the Shark Cleaner may fail to turn on, as these materials may accumulate in the vacuum, impairing its effectiveness.

How to determine if your filter needs cleaning:

Decreased suction power:

A noticeable decrease in suction power indicates that your shark vacuum’s filter needs to be cleaned. If the vacuum fails to pick up dirt and dust like it used to, a blocked filter could be the culprit. A hose or brush roll jam can also cause reduced suction power; cleaning the filter should be the first step in troubleshooting the problem.

Increased Noise:

A loud noise is another signal that your Shark vacuum filter needs cleaning. A clogged filter can force the motor to exert more effort, increasing noise levels. If you hear a high-pitched whine or hum, it’s time to clean the filter.

Unpleasant Odor:

A dirty filter can cause foul odors in the air. A clogged filter in your shark cleaner can cause unpleasant odors. Cleaning the filter will eliminate odors and improve the air quality in your home.

Debris and Dust Emissions:

If you notice dust and debris emitting from your Shark Cleaner, this indicates a jammed filter. The filter’s role is to capture unwanted particles, and if it’s not working properly, the vacuum’s cleaning efficiency will be compromised.

Visible buildup on the filter:

If dirt and debris accumulate, it’s time to clean it. A clogged filter on your Shark vacuum reduces suction power and cleaning efficiency. Cleaning the filter is essential to restore optimum performance.

Cleaning the filter on your Shark Cleaner is a straightforward process. Here are the steps you need to take:

  • Identify the type of filter your machine uses, using HEPA filters, foam filters, and felt filters, which are the most common.
  • To clean a HEPA filter, tap it gently against a trash can. Avoid using water to clean a HEPA filter and replace it with a new one if it is excessively dirty.
  • Remove a foam or filter from the vacuum and run water over it until it is clear. Squeeze out excess water before allowing it to air-dry completely before reinstalling the vacuum.
  • For washable filters, refer to the manufacturer’s instructions for proper cleaning. Some replaceable filters can be machine-cleaned; others may require hand washing with soap and water.
  • If the filter on your cleaner is removable, replace it with a new one when the old one gets dirty.
  • After cleaning or replacing the filter, ensure it is properly reinstalled in the vacuum before using it again.

Thermal Cut-off

Many modern vacuums, including the Shark, include a thermal cut-off switch to stop the motor if it overheats. 

If your vacuum suddenly stops working, this safety feature may have been triggered by overheating. Before restarting the vacuum, give it enough time to cool down, usually 30 minutes to an hour.

During this cooling period, inspect the vacuum for any signs of burning. Make sure exhaust vents are unblocked and the vacuum receives adequate airflow when in use. 

If the thermal cut-off switch is easily accessible, check for a restart button and press it if necessary. This step can sometimes solve the problem and restore normal operation to your vacuum.

Shark Vacuum Brush Roll

Shark Vacuum Brush Roll

By cleaning dirt and debris from carpets and other surfaces, the brush roll is the component that is responsible for this task. In the case that the brush roll is blocked or jammed, it is possible that the vacuum apparatus will not switch on.

Follow these steps to inspect the brush roll:

  1. Disconnect the device and locate the brush roll.
  2. Clean the brush roll by removing any hair, thread, or debris tangled around it.
  3. Make sure the brush roll is not broken or deformed. If you see any signs of deterioration, consider replacing it.

Shark Vacuum Batteries

To function properly, cordless shark vacuums rely on built-in lithium batteries. As a result, these vacuums incorporate a protective mechanism that prevents them from turning on when the voltage or remaining battery charge drops below a certain level. 

It is applied to protect and prolong battery life.

If you experience this problem, it is very important to carefully assess the battery charge level and replenish it if necessary.

Additionally, most lithium battery chargers conduct a pre-charging battery inspection to identify potential problems before charging. 

If the battery is overheated, overcooled, or over-discharged, the charging process will not start.

There is also the possibility of a problem with the charger, such as a blown or tripped electrical breaker or fuse, an unplugged charger, or a faulty charger.

Shark Vacuum Motor

If none of the techniques mentioned above proves effective, there may be a problem with the vacuum’s motor, which acts as the heart of the machine.

The motor powers the vacuum; it may fail to function if it breaks or wears out. In such cases, repair or replacement of the motor, or even the entire unit, may be necessary.

To attempt to restart a motor:

  • Turn off your Shark vacuum.
  • Disconnect the cord from the wall plug.
  • Inspect the filter and hose for any clogs and clean them.
  • Allow the machine to cool for at least 45 minutes.
  • Restart the vacuum and try cleaning again.

Shark Vacuum Is Overheating

To address a Shark vacuum that is overheating, follow these steps:

  1. Disconnect the vacuum from the power source and turn it off.
  2. Examine the filters and hose for potential clogs. Remove any debris or obstructions hindering airflow.
  3. Clean the filter and empty the trash can. A dirty screen can contribute to the vacuum overheating.
  4. Check the brush roll for knots or debris. Eliminate anything obstructing the proper turning of the brush roll.
  5. Before you use it again, let the vacuum cool down for at least 45 minutes. Too much heat can hurt the motor and other parts.

If the issue persists:

  • Inspect the belt for wear or damage. A worn-out or broken belt can prevent the brush roll from turning, leading to overheating.

If the vacuum continues to overheat:

  • Contact Shark’s customer service for assistance. They may identify the problem, provide a solution, or guide you on the next steps.
