Nobody admits to using an electric hair clipper anymore--but they still sell briskly. And, because they are relatively inexpensive (about the price of one or two haircuts) some models are subject to frequent problems. It's a good thing that hair clippers are relatively easy to fix.

How Does It Work?

An electric hair clipper is a small motorized appliance that moves cutting blades across stationary blades to cut hair. An electric beard trimmer operates in the same way, except the motor and blades typically are smaller. Even electric dog grooming clippers operate similarly. The clipper is powered either by household current through an electric cord or by a rechargeable battery.

Remove the fasteners holding the hair clipper head in place.

What Can Go Wrong?

Many repairs to hair clippers and beard trimmers can be avoided by cleaning the appliance after every use and following the manufacturer's maintenance guidelines. In addition, the electric cord may need replacing, the recharger may need service, or the motor may be faulty. The cutting blades can become clogged and the cutting edges can be damaged. Fortunately, you can make many repairs yourself. Some new models actually clean themselves.

Remove the fasteners holding the two halves of the case in place to expose the motor and switch.

How Can I Identify the Problem?

If the clipper doesn't work at all, make sure power is on at the electrical receptacle , check the battery and recharge it if it is low or check the electrical cord . Unplug the unit, turn it over and manually move the blades. If necessary, test the motor and switches.

If the hair clipper or beard trimmer operates slowly, clean and lubricate it as directed by the owner's manual. For rechargeable units, check the battery and recharge if needed.

If the unit is noisy or cuts poorly, clean and lubricate it. Also check the motor .
