Shark Navigator Lift-Away Professional NV356E Not Turning On

Is your Shark Navigator Lift-Away Professional NV356E refusing to power on? It can be incredibly frustrating when your vacuum cleaner suddenly stops working, especially when you’re in the middle of cleaning. This guide will help you diagnose the problem and provide step-by-step solutions to get your Shark Navigator NV356E back up and running. We’ll cover common causes, troubleshooting tips, and preventative measures to keep your vacuum working smoothly.

This article provides a comprehensive guide to troubleshooting why your Shark Navigator Lift-Away Professional NV356E isn’t turning on. We will explore common culprits such as power supply issues, clogged filters, and motor overheating, providing actionable solutions for each. By following these steps, you can often resolve the issue yourself, saving time and money on repairs or replacements. We’ll also cover preventative measures to keep your vacuum in optimal condition and avoid future power-on problems.

Check the Power Supply

The first thing to verify is the power source. A faulty power supply is a common reason why your Shark Navigator Lift-Away Professional NV356E won’t turn on.

1. Inspect the Power Cord: Look for any visible damage to the cord, such as cuts, fraying, or exposed wires. Even minor damage can interrupt the power supply.
2. Test the Outlet: Plug another appliance into the same outlet to ensure the outlet is working correctly. If the other appliance doesn’t work, the issue is with the outlet, not the vacuum.
3. Try a Different Outlet: If the outlet seems fine, try plugging your Shark Navigator into a different outlet in another room to rule out any localized electrical issues.
4. Examine the Plug: Check the plug itself for any signs of damage or loose prongs. If the plug is damaged, it may need to be replaced.

Clean or Replace Filters

Clogged filters can cause the vacuum to overheat and shut down as a safety measure. Regularly cleaning or replacing your Shark Navigator NV356E filters is crucial for maintaining its performance.

1. Locate the Filters: The NV356E typically has two filters: a pre-motor filter (foam and felt) and a HEPA filter (post-motor). Refer to your owner’s manual for the exact location.
2. Remove the Filters: Carefully remove the filters from their compartments.
3. Clean the Pre-Motor Filters: Wash the foam and felt filters with warm water and mild detergent. Rinse thoroughly until the water runs clear and allow them to air dry completely (usually 24 hours) before reinstalling.
4. Clean the HEPA Filter: The HEPA filter is usually not washable. Gently tap it over a trash can to remove loose dirt and debris. If it’s heavily soiled, consider replacing it.
5. Reinstall the Filters: Once the filters are completely dry, reinstall them securely in their proper locations.

Clear Any Blockages

Blockages in the hose, wand, or brush roll can strain the motor, causing the vacuum to overheat and not turn on. Regularly checking and clearing these areas is essential.

1. Inspect the Hose: Detach the hose from the vacuum and check for any obstructions. Use a long, flexible object (like a broom handle or a straightened coat hanger) to dislodge any debris.
2. Check the Wand: Remove the wand and inspect it for blockages. Clear any obstructions using the same method as with the hose.
3. Examine the Brush Roll: Turn the vacuum over and inspect the brush roll. Remove any hair, string, or debris that may be wrapped around it. Some models have a removable brush roll for easier cleaning.
4. Inspect the Nozzle: Check the floor nozzle for any obstructions that could be preventing the vacuum from turning on.

Reset the Motor

Some vacuum cleaners have a thermal protection feature that shuts off the motor when it overheats. If your Shark Navigator NV356E has overheated, resetting the motor might solve the problem.

1. Unplug the Vacuum: Disconnect the vacuum cleaner from the power outlet.
2. Allow to Cool Down: Let the vacuum sit unplugged for at least 30-60 minutes to allow the motor to cool down completely.
3. Check for Blockages: While the vacuum is cooling down, inspect and clear any potential blockages in the hose, filters, or brush roll.
4. Plug-In and Test: After the cool-down period, plug the vacuum back into the outlet and try turning it on.

Check the Brush Roll Switch

The brush roll switch, if faulty, can prevent the vacuum from turning on. Make sure the switch is properly engaged.

1. Locate the Brush Roll Switch: Find the brush roll switch on the vacuum cleaner. This switch usually controls whether the brush roll is on or off, often marked as “I” for hard floors (brush roll off) and “II” for carpets (brush roll on).
2. Test the Switch Positions: Try toggling the switch between the different positions. Sometimes a switch can get stuck or malfunction.
3. Listen for Motor Engagement: As you toggle the switch, listen for any sound indicating the motor is trying to engage. If you hear a humming sound but the brush roll isn’t spinning, there may still be a blockage or an issue with the brush roll motor.

Examine the Belt

The belt that drives the brush roll can sometimes break or slip off, preventing the brush roll from spinning and, in some cases, causing the vacuum not to turn on.

1. Access the Brush Roll: Turn off and unplug the vacuum cleaner. Locate the brush roll cover, which is usually held in place by screws or clips. Remove the cover to access the brush roll and belt.
2. Inspect the Belt: Check the belt for any signs of damage, such as cracks, fraying, or breakage. If the belt is broken, it will need to be replaced.
3. Check Belt Position: If the belt is intact, make sure it is properly seated around the brush roll and the motor shaft. Sometimes, the belt can slip off its track, preventing the brush roll from spinning.
4. Replace If Necessary: If the belt is damaged or worn, replace it with a new belt designed for your Shark Navigator NV356E model.

Seek Professional Repair

If you’ve tried all the above steps and your Shark Navigator Lift-Away Professional NV356E still won’t turn on, it may be time to seek professional help.

1. Contact Shark Support: Reach out to Shark customer support for additional troubleshooting assistance or to inquire about warranty options.
2. Find a Local Repair Shop: Look for a reputable appliance repair shop in your area that specializes in vacuum cleaner repairs.
3. Provide Model Information: When contacting support or a repair shop, provide the model number (NV356E) and a detailed description of the problem.

FAQ Section
