How to Fix a Paper Shredder Not Working: Ultimate Troubleshooting Guide

Is your paper shredder not working? Our ultimate troubleshooting guide covers how to fix jams, reset overheating motors, clean sensors, and resolve power issues for all major brands.

You can fix a shredder that isn’t working by checking it for issues, running it in reverse mode, or inserting a filing folder. Allowing the paper shredder to cool down, unplugging it, and manually removing the blockage also works. You might also need to lubricate the shredder.

Check the Shredder for Any Issues

When a paper shredder stops working, it’s tempting to immediately open the top cover and check the blades and shafts for anything out of the ordinary.

Power Cable

Check the power cable if it’s securely plugged into the power outlet. You can also try plugging it into an alternate power source or another appliance into the power outlet to see if it’s working.

Cutting Head and Waste Basket

As a safety feature, some shredders will not work if the cutting head or wastebasket isn’t properly positioned. The cutting head is what pulls the paper into the machine for shredding to commence, while the waste basket is where the shredded materials end up.

With the paper shredder unplugged, ensure that the cutting head is placed securely on the rim of the waste basket. Some models have a built-in interlock mechanism that will only work with the waste basket that came with the shredder. There will also be an activation switch that will cut the power off if it detects the head is lifted or not in place.

Only use the designated wastebasket and do not line it with a plastic bag because that may cause interference. Connecting the head to the waste basket should require little guesswork since most have matching ridges.

Be cautious when mounting the shredder onto the wastebasket since some may have exposed blades.

You should also empty the wastebasket regularly. If the bin becomes too full, the paper may not be able to flow through the shredder efficiently, making paper jams more likely to occur. Some machines will also stop working when the shredder bin is full.

Run the Shredder in Reverse Mode

If your paper shredder is powering up but still encountering problems with shredding, you may have a paper jam. Paper jams are not uncommon, and they may still happen if your shredder is labeled “Jam Free.” Jam-free shredders merely have sensors that will shut the shredder down if it detects that the load exceeds what it’s capable of shredding.

Your shredder may have any of the following symptoms if there is a paper jam:

The shredder has difficulty pulling in the paper.
The paper leaves the shredder not thoroughly shredded.
The shredder stops working while shredding.
The shredder makes more noise than usual.

If your shredder has a paper jam, try to remove the blockage by putting your shredder in REVERSE mode. The reverse function primarily addresses paper jams by forcing the paper back out.

Allow the shredder to operate in reverse mode for a few seconds to dislodge any materials causing the blockage. You can gently pull the uncut paper to assist as the machine pushes the paper back out.

It also helps to toggle between the reverse and forward mode to free up the jammed paper, and you should alternate between the two functions for about three seconds each way.

Insert a Filing Folder Into the Shredder

If you can pull out the uncut paper during STEP 2, but the shredder still shows symptoms of a paper jam, insert a filing folder or any stiff piece of cardstock into the shredder. The stiffness of the folder can help dislodge any paper causing the jam.

Place the filing folder in the center of the paper feeder and then run the machine in forwarding mode. Apply pressure to push the folder through the slot while the shredder runs.

Allow the Paper Shredder To Cool Down

Over use or jammed blades can cause a shredder to overheat. Allow your paper shredder to cool down, and leave it for at least 30 minutes before turning it on again. More Details Below.

Unplug the Paper Shredder

There are instances when you will have to inspect the internal parts of the shredder and manually unclog a paper jam. Before attempting to work on your shredder, turn it off and unplug it from the power outlet.

Manually Remove the Blockage

After unplugging your shredder, detach the shredder section from the wastebin and the entire machine. You should refer to your owner’s manual to check how to do this for your specific model. Always be cautious of exposed blades that can cause injury.

Once you have access to the shredder’s blades, inspect them from the top and the bottom for blockages. Always use tools when trying to unclog a shredder, and never allow your fingers to touch the blades, otherwise, you risk cutting yourself.

Use needle-nose pliers or tweezers to remove loose bits of paper or materials that are hard to reach. You may have to use a knife or scissors to cut some shreds that get tangled around the blades or the cylindrical rollers of the shredder.

If you see more rigid material like plastic or cardboard stuck in the shredder blades, use a flat screwdriver to dislodge them. Just be careful not to apply too much force that you damage the blades or other shredder components.

How to Clean Paper Shredder Sensors

Disconnect Power: Always unplug the shredder before cleaning to prevent the motor from accidentally engaging while your hands or tools are near the blades.
Locate the Eye: Look inside the paper feed slot. Most shredders have a small, clear glass or plastic infrared sensor located right in the center of the throat.
Clear Physical Obstructions: Use a pair of tweezers or a thin wooden skewer to gently remove any tiny paper scraps or lint caught directly over the sensor lens.
Use Compressed Air: Give the sensor area a few quick blasts with a can of compressed air. This is the most effective way to clear deep-seated paper dust without touching the components.
Wipe with Isopropyl Alcohol: Dampen a cotton swab with a small amount of rubbing alcohol. Gently wipe the sensor lens to remove oils or sticky residue that air won’t budge.
Dry and Test: Ensure the area is completely dry before plugging the unit back in. Run a single sheet of paper through to confirm the “Auto-Start” and “Auto-Stop” functions are restored.

Lubricate the Paper Shredder With Shredder Oil

For stubborn clogs, you can lubricate the paper shredder with oil. The oil can soften the paper and make it easier to remove from the blades.

Some lubricants are designed specifically for shredders, but you can also use cooking oil. Never use spray can oils, penetrating fluid, or other lubricants. The Bonsaii Paper Shredder Lubricant Oil (available on amazon.com) works on all shredders and comes with an oblique nozzle, making it easy to apply on shredder blades and paper.

To remove a clog using shredder oil, follow these instructions:

Turn the paper shredder off.
Apply a few drops of oil to the blades with paper jammed.
Let the jammed paper soak for at least 30 minutes.
Turn the shredder on and shred a filing folder to push the jammed paper through.

Aside from dealing with paper jams, you should lubricate your shredder at least once a month to keep it in good running condition. A noisy paper shredder also indicates that it needs to be lubricated.

If you’re lubricating your shredder as part of routine maintenance, follow these instructions:

Soak a sheet of paper with oil or use a shredder lubricant sheet.
Run it through the shredder.
Follow up by shredding a dry sheet of paper.
Test the Paper Shredder

After removing the paper jam, your shredder should work as well as new. Test the paper shredder by shredding a new batch of documents.

Expert Tip: According to the EZ Office Products, you should oil paper shredders for every 30 minutes of shredding time.

Paper Shredder Won’t Turn On? Check these 5 Things

Check the Waste Bin

Check the bin engagement sensor. Many people think a shredder “won’t turn on” when actually the wastebasket isn’t pushed in far enough to engage the safety interlock switch.

Check for a Blown Fuse/ Power Issues

Power Issues: check for tripped breaker and power strip that got turned off. Also, a shredder not turning on could be due to a blown fuse. You can quickly fix this problem by following the steps below.

Unplug the shredder from the power outlet.
Remove the top cover of the shredder and check for any visible damage to the fuse.
Replace the fuse if it’s faulty.

Check if the Shredder Safety Interlock Is On

The shredder safety interlock is an important safety feature that prevents the shredder from running when you’re not using it. It is an excellent feature for those with small children or pets at home who want to ensure they are safe around the machine.

You can check if the shredder safety lock is on by checking if the safety lock warning light is on. The warning light’s location depends on the shredder model.

check to see if shredder is overheating

An overheated shredder might temporarily stop working and fail to turn on. This is to protect the motor and requires a cool-down. Read more details below.

The Cool-Down Wait: Once a shredder overheats, the cool-down period is almost always significantly longer than the run time. A basic model that shreds for 3 minutes may require a 30 to 40-minute break to reach a safe operating temperature.

Check if Your Shredder Is Jammed or Clogged

If the shredder is jammed or clogged, the blades cannot rotate. The blades can jam for several reasons. The most common one is the paper not being inserted correctly. Other causes include a buildup of shredded paper and paper clips on the blades. If this is the case, you will need to open the device and remove any obstructions.

How to Unjam a Shredder?

To unjam your shredder, follow these steps:

Remove the paper from the shredder.
Unplug the shredder and take it apart.
Open the device, and remove pieces of paper or anything that may have jammed the shredder’s blades or gears.
Place all the parts back together and plug the device in again.

Why Paper Shredders Overheat: Key Takeaways

Exceeding the Duty Cycle: Most shredders have a “run time” (usually 2–10 minutes). Going beyond this triggers the thermal safety switch to prevent motor burnout.
High Friction from Dry Blades: When blades aren’t oiled, they create excessive heat as they rub together. Regular lubrication reduces the workload on the motor.
Overloading Sheet Capacity: Feeding the maximum number of sheets (or more) forces the motor to draw more power, which generates heat much faster than shredding smaller stacks.
Paper Dust & Debris Buildup: Dust can clog internal ventilation and coat the motor, acting as insulation that traps heat inside the machine.
Full Waste Bins: If the bin is packed tight, paper can “back up” into the cutting head, causing the blades to struggle and the motor to strain.
Poor Ventilation: Placing a shredder in a tight corner, under a desk, or near a heater prevents the ambient air from cooling the internal components during use.

Quick Fix: If your shredder stops, allow it to cool for 30–60 minutes before trying again. Forcing it to start early will only result in a shorter next run time.

How Te Reset a Paper Shredder

Turn off the paper shredder.
Allow the paper shredder to cool for an hour.
Pull out papers from the rollers.
Use a vacuum to remove paper dust.
Oil the blades.
Clean the shredder sensors.
Turn on the paper shredder.
