Common Reasons Why Your Shark Apex Vacuum Won’t Turn On

There are several possible causes for a Shark Apex vacuum failing to power on. Let’s explore the most common culprits:
Power Cord and Outlet Issues
The most basic things are sometimes overlooked. It is recommended to start here to avoid any unnessecary troubleshooting.
- Check the Power Cord: Examine the entire length of the power cord for any visible damage, such as cuts, fraying, or exposed wires. A damaged cord is a safety hazard and can prevent the vacuum from receiving power.
- Test the Outlet: Plug the Shark Apex into a different outlet to rule out a faulty outlet as the cause. You can also use a multimeter or test another appliance to verify the outlet is providing power.
- Reset the Circuit Breaker: If the outlet isn’t the issue, check your home’s circuit breaker or fuse box. A tripped breaker or blown fuse can cut power to the outlet. Reset the breaker or replace the fuse if necessary.
Overheating
Vacuums can overheat during use, especially if there are blockages. Overheating can cause the vacuum to shut down.
- Allow the Vacuum to Cool Down: If the vacuum has been running for an extended period, it may have overheated. Turn it off and let it cool down for at least 30 minutes before attempting to restart it.
- Check the Thermal Cutoff Switch: Some Shark Apex models have a thermal cutoff switch that automatically shuts off the motor when it overheats. Consult your user manual to find the location of the switch and how to reset it.
Blockages in the Vacuum
Blockages in the vacuum can cause it to not turn on. Make sure to check all the possible locations for blockages.
- Inspect the Nozzle and Hose: Disconnect the nozzle and hose from the vacuum body and inspect them for obstructions. Use a long object, such as a broom handle or a straightened coat hanger, to dislodge any blockages.
- Check the Dust Cup and Filters: A full dust cup or clogged filters can restrict airflow and cause the vacuum to overheat or fail to start. Empty the dust cup and clean or replace the filters according to the manufacturer’s instructions.If the dust cup is cracked or the filters are too worn out to clean effectively, consider getting replacements. You can find replacement dust cups and filters for Shark Apex Vacuum on Amazon to keep your vacuum working efficiently.
Issues with the Motor
The motor is what causes the vacuum to turn on, and if it is defective, it will prevent the vacuum from turning on.
- Listen for Unusual Noises: When you try to turn on the vacuum, listen for any unusual noises coming from the motor, such as grinding, squealing, or rattling. These sounds could indicate a motor problem.
- Smell for Burning Odors: A burning smell emanating from the vacuum is a sign of a serious motor issue. Immediately turn off the vacuum and unplug it.
- Check the Motor Brushes: If your Shark Apex model has accessible motor brushes, inspect them for wear or damage. Worn brushes can prevent the motor from starting. If the motor brushes are worn down or damaged, it’s best to replace them. You can buy replacement motor brushes for Shark Apex vacuums on Amazon to help restore your vacuum’s performance.
Switch or Control Panel Problems
If none of the above solve the issue, it could be something wrong with the switch and it is not sending the signal to turn the vacuum on.
- Test the Power Switch: Use a multimeter to test the continuity of the power switch. If the switch is faulty, it will need to be replaced.
- Examine the Control Panel: Inspect the control panel for any signs of damage, such as cracked buttons or loose connections. If the control panel is malfunctioning, it may need to be repaired or replaced.
