Hair dryers integrate both forms of tiny appliances: those that warm and those that relocate something. As such, a hair dryer contains both a heating facet and also a fan motor.

Most human being don"t bvarious other to deal with even the simplest difficulties on their hair dryers because they are mostly inexpensive to replace. It"s easier to toss them and also buy new ones. In the long run, however, it may be more efficient to purchase a better-quality hair dryer and make the majority of of the repairs yourself.


How Hair Dryers Work

Personal hair dryers come in a selection of shapes and sizes, yet they all contain the very same components and work in the very same means. The typical hair dryer includes an on/off switch, a fan-rate switch, a fan and motor, a warmth switch, a heating element, and a thermal cutout switch.

The heating switch controls the amount of existing yielded to the heating aspect, hence controlling the heat ceded by the hair dryer. The fan-speed switch controls the speed of the fan motor and also fan, thus regulating the pressure of the air yielded by the hair dryer. The thermal cutout switch, a safety attribute, shuts off the heating facet if it gets as well warm.

How to Repair a Hair Dryer

Typical hair dryer repairs incorporate servicing the switch, fan, heating element, and also thermal cutout.

Servicing a Switch: On/off, fan-rate, and also warmth switches all occupational in the exact same method. They control the current going to the hair dryer, the fan, or the elements.

Some switches have only two positions: on or off, high or low. Others have actually three or even more. However, they are all tested and also reput in the very same method. Here"s exactly how to test a hair dryer switch:

Step 1: Unplug the hair dryer and carefully unscrew and also rerelocate the real estate. Screws are generally recessed close to the motor vent.

Tip 2: Switches will be placed in the take care of or major real estate in between the electrical cord and also the fan motor and also heating facet. Remove the switch and disaffix it.

Step 3: Using a continuity tester or multitester, make sure the switch functions as it have to. That is, an on/off switch will certainly indicate an open up circuit (continuity light off) in the OFF position, and also a closed circuit (continuity light on) in the ON position.

Fan-speed switches and also heating element switches will present continuity in all settings.

Servicing a Fan: The fan in a hair dryer pulls air in via a vent and pushes it out the nozzle. The fan-speed switch feeds it electric existing.

Hair dryer fans are generally fairly long lasting. The primary causes of troubles are hair and

moisture -- 2 facets found in abundance in a bathroom.

Hair, lint, and other debris deserve to clog up the display screen filter on the air intake. To clean it, use compressed air or a soft-bristle toothbrush.

Moisture can damage any type of motor by shorting out components. To test and also repair a hair dryer fan and motor:

Step 1: Remove real estate screws and also lift off the real estate.

Step 2: Rerelocate and check the fan chisels, repairing or replacing as essential.

Tip 3: Test the motor utilizing a continuity tester to encertain that present has a closed path (continuity light on) through the motor. If not, remove and also relocation the motor through among an the same rating in watts and size.

If a replacement motor cannot be found, or if it costs more than fifty percent the price of a new hair dryer, take into consideration replacing the entire hair dryer.

Servicing a Heating Element: The heating element in a hair dryer is a continuous high-resistance wire wound approximately a nonconducting structure. It is mounted in the appliance nozzle or output vent. When electrical current is applied to it, the element heats up. The nearby fan pressures air past the facet, warming it prior to it exits the nozzle. To test a hair dryer aspect if you suspect a problem:

Tip 1: Rerelocate the housing of the hair dryer and the element shield.

Tip 2: Find the two wires causing the aspect. Visually check the wires and also the facet coils for any obvious breaks or debris.

Step 3: Use a continuity tester or multitester to check for continuity. The circuit between the 2 lead wires have to be closed (continuity light on). If not, examine the thermal cutout.

Step 4: If the thermal cutout features appropriately, relocation the heating element with a specific replacement component.

Servicing a Thermal Cutout: A thermal cutout is located in the aspect assembly of the majority of electrical hair dryers. The objective of a bimetallic thermostat is to shut the hair dryer element off if it gets also hot. To test the thermal cutout:

Step 1: Open the real estate and get accessibility to the element assembly.

Step 2: Find and inspect the thermal cutout for debris, distortion, or discoloration.

Step 3: Clean the contact points through emery paper. Loosen debris via a few brief blasts of compressed air held at adequate distance to prevent damages to the sensitive facet wires.

So, prior to you toss out that malfunctioning hair dryer, toaster, or other little appliance, make certain the problem isn"t a simple one to settle. The tips in this article will aid you get those family members necessities up and running aobtain.
