How to clean and fix an electric shaver

To keep a shaver in good condition, clean the head and blades regularly and inspect them for wear. Blow out
hair after each use. Periodically brush the head; clean the blades with commercial spray or liquid cleaner, following package instructions.

Worn blades or screens may cause poor cutting or excessive noise. To inspect these parts in a flat-head shaver, unplug the shaver, set the selector dial on Clean, and lift off the shaving head. Push out the blades from the screen. In a curved-head shaver, lift off the screen and remove the cutter or the multiple oscillating blades. Look for gaps in the screen and nicks in the blades. Replace defective parts or the entire head. Return flat-head blades to the slots they came from; put multiple oscillating blades back in their original order.

To inspect a rotary-blade shaver, remove the shaving head assembly and loosen the knob at the back that holds the retaining plate. Remove the plate and inspect the cutters and cutting screens. Defective screens and cutters must be replaced as a unit.

If the motor falls to run

Make sure the outlet is working and the shaver’s dual voltage switch, if any, is properly set. Test the cord with a continuity tester; in cordless shavers, the power pack may have to be replaced.

A jammed head can cause the motor to hum but not run. If the shaver runs normally with the head off, replace the head.

If the power supply and head are all right, the On-Off switch, the motor, or the drive assembly may be at fault. Take the shaver to an authorized repair shop for servicing.
