Electric Shaver Repair

This Fix-It Guide on electric shaver repair tells how an electric shaver works, what often goes wrong, how to identify an electric shaver problem, and what parts and tools you will need to fix it. It then gives simple step-by-step instructions for how to service a foil-head electric shaver and how to service a rotary-head electric shaver. This guide also refers to battery repair, battery charger repair, electrical cord repair, motor repair, and appliance controls repair for more detailed help.

How Does an Electric Shaver Work?

An electric shaver is a motorized small appliance for cutting body hair. A motor inside the shaver moves miniature blades. A fine screen holds the hairs that protrude through the screen so that the cutting blades can slice through them. The shaver is powered by either household current through an electric cord or an internal rechargeable batteries.

The two most popular types of electric shavers are foil-head and rotary-head. A foil-head shaver moves rows of blades back and forth using an oscillator. A rotary-head shaver’s motor rotates three blades in unison, each with its own gear, blade, and screen.

What Can Go Wrong with an Electric Shaver?

Many repairs to an electric shaver can be avoided by cleaning the appliance after every use and following the manufacturer’s maintenance guide. In addition, the electric cord may need replacing, the recharger may need service, or the motor may be faulty. The head can become clogged and the cutting edges can be damaged. Fortunately, you can make many repairs yourself.

Fix-It Tip

The best way to avoid problems with your electric shaver is to regularly inspect and maintain it. Review the owner’s manual for specific requirements of your model.

How Can I Identify an Electric Shaver Problem?

Most electric shaver problems are easily identified and resolved.

  • If a shaver doesn’t work at all, make sure power is on at the outlet, check the battery and recharge it if it is low, and check the electrical cord. If necessary, test the motor and switches (see the Appliance Controls Fix-It Guide).
  • If an electric shaver operates sluggishly, clean and lubricate the heads. For rechargeable units, check the battery and recharge if needed. If the shaver is noisy or cuts poorly, clean and lubricate the shaver. Also check the motor. On foil-head shavers, check the oscillator.
  • If a shaver pinches skin, check the screen for corrosion or damage and service the head.

What Are the Steps to Electric Shaver Repair?

A foil shaver is relatively easy to disassemble and service. Your model may vary from this illustration, but the components are the same.

Service a foil-head electric shaver:

  1. Unplug the appliance. Remove the head assembly held on by screws, clips, or a pressure button.
  2. Remove the screen from the head and carefully clean it. If the screen is damaged or corroded, replace it.
  3. Remove the blade assembly from the oscillator assembly. Inspect and clean the blade assembly with canned air.
  4. If your foil-head shaver requires lubrication, follow the manufacturer’s instructions for doing so.

If your electric shaver is intended for use in a shower, the inner workings will be protected from moisture by O-ring seals that require professional service.

Rotary-head shavers, too, are simple to maintain with periodic cleaning and lubrication.

Service a rotary-head electric shaver:

  1. Unplug the appliance. Remove the head assembly from the housing.
  2. Remove the shaver head from the blade assembly and place the assembly on a flat surface.
  3.  Remove the screens and the blade unit. Clean the screens with a small brush and inspect the blades. If the screen is damaged or corroded, replace it.
  4. If your rotary-head shaver requires lubrication, follow the manufacturer’s instructions for doing so.


Water and electricity don’t mix. Be extra careful using a plugged-in shaver around the sink. And never use a corded shaver in the shower or tub!
