Are your hair clippers not cutting hair? Well, you're not alone; after all, your hair clipper can stop working with time. Therefore, instead of purchasing a new pair of Wahl clippers, you should first find out the cause of the issue.

Some of the common causes of this issue include a dull cutting blade or a loose blade. So here are step-by-step instructions on how to fix hair clippers that won't cut.

Troubleshooting Tips To Fix Your Hair Clippers

Check the cutting blade teeth for damage

If your hair clippers won't cut hair properly, the first thing to do is assess the condition of the blades. If you haven't replaced or sharpened them in a while, they may be worn or damaged.

If you're dealing with blunt blades, then you can sharpen them. 

If not, then you can examine the stationary blade for scratches or unevenness.

If there's obvious damage, it's time for new trimmer blades. Therefore, you should find out which options are suitable for your model or universal blades.

When installing new hair clipper blades, make sure they are lined up correctly and all parts, like screws and clips, are tightened. If it still doesn't work properly, take it to an expert who can diagnose any potential electrical problems.

Check the tension of the clipper blades

Check the tension of the blades to ensure they are not too loose. This can be done with an Allen wrench or screwdriver, depending on your model.

If the clippers still don't cut correctly, examine them for any buildup of hair and residue. 

Remove with a soft brush and cleaning cloth or rag dampened with rubbing alcohol.

Pay attention to clipper oil levels, and add more as needed. Not doing so can cause overheating, poor performance, damage, or even a fire hazard.

Check the power source of the hair clipper

If your hair clippers won't cut, the problem could be the cord. Check for any physical damage. If the clipper was dropped, twisted, or stepped on, the cord may be frayed, opened, or broken.

If there is no damage, use a multimeter to measure voltage flow through the supply line conductors. If a reading other than zero is present, the line needs replacing.

If neither of these tests yields any results, there could be an obstruction inside the motor. Disassemble it according to product specs and clean dust particles and hair fragments near the blades.

Cleaning and Maintenance

Regular maintenance and cleaning of your hair clippers is key! To keep them in top shape and avoid any accidents, here's what you need to know.

Tips for cleaning and maintaining your clippers: that'll help them last longer.

Clean the hair clipper blades

Unplug your hair clipper and remove the blades. Rinse them in warm water for a few seconds. Then dry with a cloth.

Get a brush or old toothbrush to take out stuck-on hair. Use tweezers if your hair is thick. 

Put baby oil or a light lubricant like WD40 or 3 in 1 oil on the blades. This reduces friction and makes sure they work properly.

Reassemble and plug in your clipper. You're all set for another great cut!

Oil the clipper blade

Oil your clippers for better performance and longevity. Switch them off first so you don't hurt yourself. Use an aerosol spray or oil-based lubricant. Vegetable oil and clipper blade coolant can also be used.

Get all the moving parts, like the blade guard and other attachments. Wipe off any excess oil or buildup. Clean your blades twice a week to extend their life.

Replace the blades

If the clippers make noise but don't cut, this might indicate something is wrong with the blades. Replace them if they are dull or have oil or product residue. It's easy to do at home but do it safely and correctly. Wrong replacement can ruin the clippers or cause injury.

Disconnect the clippers from power. Then release levers or clips, according to instructions. Most blades are held by two metal plates. Unscrew and replace them, matching the info in the manual.

Be careful not to touch the blade surface. The replacement should fit and work smoothly, without force. Secure the blades back in place. Fasten all connections properly. Follow instructions.

Turn the clippers on. If still loud, there could be other issues apart from blade dullness. Its power screw may need to be adjusted. Refer to the manual for guidance.

Other Considerations

Excess hair, dirt, and oil buildup are common clipper problems. However, improper use and maintenance, insufficient lubrication, and incorrect blade set-ups can also affect performance. Age and condition of blades can also be an issue.

Consider these other factors that might be causing clipper malfunctions.

Check the power cord

When troubleshooting hair clippers that don't work, first check if it's properly plugged in. Inspect the power cord for burns or fraying wires, and replace it if needed.

Check the circuit breaker switches, too - if tripped, it won't get power. 

If using an extension cord, make sure it can handle the amps and watts required to safely operate the clippers.

Replace the power cord

If your clipper isn't cutting properly, replacing the power cord is an option to try. Check for frays or cuts on both ends of the cord. Inspect for damages along its length like stretching, bending, or exposure.

Find a replacement power plug and cable that fits your device. Check what physical configuration and electrical rating apply. When attaching the new cord, use the correct wiring procedures. Use secure electrical connectors and insulation tape. This will help prevent live circuitry from being accidentally touched.

Replace the motor

If your clipper has been working for a long time and is showing signs of wear, or it has stopped working entirely, you may need to replace the motor. Uneven cutting, unbalanced, or strange noises could mean it's time for a new motor.

Look online to find out what type of motor your clipper uses. You can buy one from an electronics store or online shop. Installing a new motor can be tricky, so you may want to get help from a professional service center.

If all else fails, check out the best lineup clippers we have in the market. There should be one that suits your needs best! 


Are your noisy clipper blades moving but not cutting hair? Well, if it's sharp enough and well-maintained, then you need to adjust the power screw and taper lever on the side. You can lower the noise by turning it anticlockwise. But most importantly, make sure you service your cutting blades regularly.
