The parts in a hair dryer are subject to dust and high heat during the natural course of operating. So it's no surprise that those two troublemakers are often to blame when a hair dryer runs poorly or stops altogether. Often, all it needs is a good cleaning and lubrication.

Step 1

Disassemble the housing, using a screwdriver.

Step 2

Clean the heating element. With tweezers, extract any hair or lint, then use an old toothbrush to remove dust.

Step 3

Clean the inside and outside of the intake vent and filter, using an old toothbrush to loosen the grit, and a vacuum with crevice attachment to remove it.

Step 4

Vacuum the rest of the interior, including the fan, motor and switches. Use the tweezers to remove any hair that's wound around the motor or other parts.

Step 5

Spray the switches with electrical-contact cleaner to remove grit that may be preventing them from operating correctly.

Step 6

Oil the bushings at both ends of the motor with one drop of machine oil.

Step 7

Reassemble the hair dryer.
