Shark Apex Not Turning On

Your Shark Apex vacuum is a powerful cleaning tool, so it’s understandably frustrating when it won’t start. If your Shark Apex not turning on, you’re in the right place to find a solution. This guide will walk you through the most common causes and fixes, from simple checks to more involved troubleshooting, so you can get your vacuum running again without unnecessary stress or expense.

Seeing a completely unresponsive vacuum can be worrying. Before you consider a costly repair or replacement, it’s crucial to methodically check a few key areas. Most of the time, the issue is something simple that you can resolve yourself in just a few minutes. Let’s start with the easiest possibilities and work our way toward less common fixes.

Initial Quick Checks

Always begin here. These steps take seconds but solve a huge number of “won’t turn on” problems.

Check the Power Outlet: Plug a different device, like a lamp, into the same wall outlet to confirm it’s working. Sometimes a tripped circuit breaker or GFCI outlet is the culprit.
Inspect the Power Cord: Look along the entire length of the cord for any visible damage, cuts, or fraying. If you find any, stop using the vacuum immediately.
Ensure Proper Connection: Make sure the cord is firmly plugged into both the wall outlet and the back of the vacuum cleaner itself. It can sometimes become loose.

Primary Power System Troubleshooting

If the quick checks don’t help, the problem likely lies within the vacuum’s primary power system. Follow these steps in order.

1. Reset the Thermal Cut-Off

Shark vacuums have a thermal reset protector to prevent motor damage from overheating. If the vacuum shut off during heavy use, it may need a reset.

Turn the power switch to the “OFF” position.
Unplug the vacuum from the wall outlet.
Wait for at least 60 minutes to allow the motor to cool completely.
Plug the vacuum back in and try turning it on. Often, this is all it needs.

2. Examine the On/Off Switch

The switch itself can fail. Listen and feel for a distinct click when you press it. If it feels mushy or makes no sound, the switch might be broken. Testing this typically requires opening the vacuum’s housing, which we’ll cover later.

3. Inspect the Brushroll and Blockages

A severe blockage can cause the motor to overload and shut down. The vacuum might not restart until the blockage is cleared.

Turn the vacuum over and manually spin the brushroll. It should move freely without any grinding or resistance.
Remove the brushroll and clear any wrapped hair, string, or debris from both the roll and its bearings.
Check all hose connections, the wand, and the base for clogs. A common spot is where the hose attaches to the dust cup.

Battery-Specific Issues (For Cordless Apex Models)

If you have a cordless Shark Apex, the troubleshooting path is different and focuses on the battery and charger.

Check the Charger: Ensure the charging dock is plugged in or the charger is connected properly. Look for a solid light on the charger or vacuum to indicate it’s receiving power.
Reseat the Battery: Remove the battery from the vacuum by pressing the release buttons. Check the terminals for dirt or debris, wipe them clean if needed, and reinsert the battery firmly until it clicks.
Perform a Hard Reset: With the battery removed, press and hold the power button on the vacuum for 15-20 seconds. Then reinstall the battery and try turning it on.
Test with Another Battery: If possible, try a known-good battery from another compatible Shark vacuum. This will tell you if the problem is the battery or the vacuum itself.

Advanced Internal Checks

Warning: Only proceed if you are comfortable with basic tools and understand that opening your vacuum may void its warranty. Always unplug the vacuum first.

Checking Internal Wiring and Connections

Loose wires inside can interrupt power. You’ll need a screwdriver to open the main housing (usually on the top or back of the vacuum).

Locate and remove the screws holding the plastic shell together.
Gently separate the housing. Look for any wires that have come disconnected from the switch, motor, or circuit board.
Also look for any signs of burning, melted plastic, or a distinct burnt smell, which point to a serious motor or electrical fault.

Testing the On/Off Switch with a Multimeter

If you have a multimeter, you can check the switch for continuity.

Disconnect the vacuum from power.
Locate the two wires connected to the switch.
Set your multimeter to the continuity setting (it looks like a sound wave symbol).
Touch the probes to the two switch terminals. With the switch in the “ON” position, you should hear a beep, indicating continuity. No beep means a faulty switch that needs replacement.

When to Consider a Motor or Professional Repair

If all other checks fail, the issue may be the main motor. Signs include a burnt smell, visible damage inside, or the motor humming briefly but not starting. Replacing a motor in a Shark Apex is a significant repair.

Cost Consideration: Weigh the cost of a new motor plus your time against the price of a new vacuum. For older models, replacement is often more economical.
Official Support: Contact Shark Customer Service. They can provide guidance, and if under warranty, arrange for a repair. Have your model number (found on the rating plate) ready.
Local Repair Shops: An appliance repair shop can offer a diagnostic for a fee. Get a quote before authorizing any work.

Preventative Maintenance to Avoid Future Problems

Regular care can prevent many “not turning on” issues. It’s worth making these habits.

Empty the Dust Cup Frequently: Don’t let it fill past the “MAX” line. A overfull cup strains the motor and airflow.
Clean Filters Regularly: Rinse the foam and felt filters with cold water every month. Let them air dry for at least 24 hours completely before reinstalling. A clogged filter is a major cause of overheating.
Clear Brushrolls After Every Use: Regularly cut away hair and fibers wrapped around the brushroll to maintain free movement and prevent belt wear.
Store Properly: Keep the vacuum in a cool, dry place and avoid yanking the cord from the outlet by the wire itself.

Frequently Asked Questions (FAQ)

Why did my Shark Apex suddenly stop working?

The most common reasons are an overheated motor (requiring a reset), a tripped household circuit breaker, or a severe clog. Always check for blockages and let the vacuum cool down for an hour before trying again.

How do I reset my Shark Apex vacuum?

For corded models, simply unplug it from the wall and wait 60 minutes for the thermal protector to reset. For cordless models, remove the battery, press and hold the power button for 15 seconds, then reinsert the battery.

Where is the reset button on a Shark Apex?

Shark Apex vacuums don’t have a manual reset button. The thermal reset is automatic but requires the vacuum to be unplugged and cooled down as described above.

What should I do if my Shark Apex makes a humming noise but won’t start?

A humming noise usually indicates the motor is getting power but something is preventing it from spinning. This is almost always caused by a jammed brushroll or a blockage in the airflow path. Immediately turn it off, unplug it, and clear any obstructions.

How long does a Shark Apex battery last before needing replacement?

A lithium-ion battery in a cordless Shark Apex typically maintains good performance for 3-5 years with regular use. Signs you need a new battery include drastically reduced run time and the vacuum struggling to maintain power even after a full charge.

Is it worth repairing an Shark Apex that won’t turn on?

It depends on the cause and the age of your vacuum. If it’s a simple fix like a clog or a new belt, yes. For major issues like a failed motor on an older model, purchasing a new vacuum might be more cost-effective, especially if yours is out of warranty.

Dealing with a Shark Apex that’s not powering on can be a hassle, but it’s usually a solvable problem. By following this structured guide—starting with the simplest solutions—you’ll likely identify and fix the issue yourself. Remember, regular maintenance like cleaning filters and checking for blockages is the best way to keep your vacuum running strong and avoid most electrical problems in the future. If you’ve tried everything and the vacuum remains unresponsive, reaching out to Shark support with your model number is the best next step for personalized advice.
