What causes hair dryers to malfunction? Excessive heating could be the source of your condition. Just use it for 7-10 minutes and it’ll shut off on its own.

Disconnect the gadget and turn the heat down for 2 to 5 minutes, preferably in a cool environment, if this happens. Once it has cooled, the dryer can be used as normal.

The start button may need to be pressed after the hairdryer is plugged in again. All of this is, in fact, true, my friends. That, however, is insufficient. All of the possible causes and solutions for the dryer not working have been discussed. So, if you’re interested in learning more, stick around till the end!

Why Do Your Hair Dryers Stop Working?

#1. Heat issue

Applying heat to hair using a hairdryer makes styling it easier. When compared to a simple blow-dry, this method saves a significant amount of time. Over the course of the operation, however, you may have problems with heating components. The cold setting on most hair dryers is rarely used, and when it is, it usually just produces hot air. Make sure the cold switch is switched off in order to fix this issue. Check to check if your preferences have been met by this. It’s best to take the problem to a cosmetics shop if it doesn’t get fixed after checking the settings a second time. It is possible to receive a replacement or repair for a hairdryer that is still under warranty if it is new and under warranty.

#2. Noise problem

Electric plates and small blowers, powered by a worldwide engine that spins at extraordinary speeds, are the latest innovations in hair dryer technology. High torque that sounds like a plane is running in your bathroom, which is not ideal. Experts on this website advocate using a hair dryer with nano ionic hybrid technology if you want the best results.

Consider the pros and downsides of each type before making a final decision.

Hair dryers are expensive, but you can save money by drying your curly hair in a larger area or by using the diffuser on your current hair dryer. The greater the temperature setting, the more severe the sound of the hairdryer. When you’re not in a rush, use the lowest setting possible for a more pleasant blowout experience.

#3. Thermal cutoff

A hairdryer’s thermally cutoff feature keeps it from overheating and, if necessary, shuts down the heat source. Hairdryers that get hot while in use are likely to have a faulty thermal cutoff. With basic repair and maintenance skills, you may remove your hair dryer’s casing and access its wiring component to rapidly clean or inspect the heat cutoff. Instead of throwing it out, take it to a repair shop and get it fixed. Identify the source of a dryer’s thermal cutoff.

#4. Burnt switch

Hairdryer switches are a typical source of failure. If this doesn’t work at all, it should. For this issue, all you need to do is keep the control down for a long amount of time. Make sure it’s plugged into a power source. To aid if the switches or toggles have malfunctioned or simply need a little extra nudge, this could be the answer. After that, check the cord for any broken or damaged connections. Afterward It’s possible that a glue or oil buildup on the buttons is to blame if you’re unable to switch between them.

Using pressured gas, thoroughly clean and re-test the system. Changing a switchboard or switch may be all that is necessary if the problem persists. A professional repair agency should be called in to inspect your power source if none of these measures work or if you don’t understand how to change the switchboard or perform suitable technical fixes on your own. It may be possible to fix your broken hairdryer with an easy-to-follow method.

You may need to take it to a nearby repair shop or buy a new one if the easy repair approaches fail. It’s best to get professional treatment as soon as an issue arises, so that it doesn’t get any worse.

How Hair Dryers Work

Though they come in a range of shapes and sizes, personal hair dryers use the same basic parts. Fans and motors are included, as well as an on/off switch, a fan speed switch, a heat switch, and an on/off control for the thermal cutoff.

Controlling the amount of heat delivered by the hair dryer is accomplished via the heating switch. The hair dryer’s air force is controlled by the fan-speed switch, which regulates the motor’s speed and the fan’s speed. If the heating element becomes too hot, a safety device called the thermal cutout switch turns it off.

How to Repair a Hair Dryer

Switch, fan, heating element and thermal cutout are some of the most commonly repaired parts on a hair drier.

An on/off, fan-speed, and heat switch can all be serviced in the same manner. Hair dryer, fan and other elements are all controlled by these switches.

On/off, high/low are the only positions available on some switches. Others have at least three. However, they are all subjected to the same testing and maintenance procedures. Hair dryer switches can be tested using this method.

First, unplug the hair dryer and remove the housing by unscrewing and twisting. Close to the motor vent, screws are often recessed.

After the fan motor and heating element have been connected, switches will be inserted between these components in order to control their operation. Remove and unhook the switch.

The third step is to test the switch using a continuity tester or multitester. The OFF (continuity-light-off) position of an on/off switch indicates an open circuit, while the ON (continuity-light-on) position does the opposite.

All options for fan speed and heating element switch continuity will be shown.

A hair dryer’s fan pushes air out of the nozzle after drawing air in through a vent. Electricity is delivered to the fan by means of a speed control.

The majority of hair dryer fans are built to last. In the majority of cases, hair and skin are the main culprits.

In a bathroom, you’ll find a lot of both: wetness.

As a result, the screen filter on the air intake can become clogged up with lint and other particles. Compressed air or a soft-bristle toothbrush can be used to clean it.

Moisture can short out components in any motor, causing it to malfunction. Hair dryer fan and motor testing and repair:

To remove the housing, just undo the screws holding it in place and lift it out.

Step 2: Remove the fan blades and check them for damage or wear.

Using a continuity tester, check to see if the motor has a closed passage for the current to flow through. If this is not the case, take out the old motor and replace it with a new one of the same wattage and size.

A new hair dryer may be necessary if a replacement motor cannot be located or if it costs more than half the price of a new hair dryer.

This guide will show you how to clean and maintain the high-resistance wire that makes up the hair dryer’s heating element. The appliance nozzle or exhaust vent is where it is installed. The element heats up when electricity is introduced to it. The fan next to the element warms the air that comes out of the nozzle. If you suspect a problem with a hair dryer’s heating element, you can do a simple test:

Step 1: Take the hair dryer’s housing and element shield off.

Find the two wires that connect the element to the power supply. Inspect the wires and coils of the element for any noticeable breakage or debris.

A continuity tester or multitester can be used to ensure that the circuit is working properly. If there is any connection between the two lead wires, it needs to be closed off (continuity light on). Make sure the thermal cutoff is working properly.

If the thermal cutout is working properly, replace the heating element with a new one.

Most electric hair dryers have a thermal cutout in the element assembly that has to be serviced. As soon as the element of the hair dryer becomes too hot, the bimetallic thermostat will turn it off. To see if the thermal cutout is working properly:

First, open the casing to get to the components.

Second, locate and verify the thermal cutoff to ensure that it is clean and clear.

Step 3: Use emery paper to scrub the contact points clean. Using compressed air, loosen debris while keeping a safe distance from the wires of the sensitive element.

Check to make sure the problem isn’t one that can be easily fixed before you throw out your broken hair dryer or toaster. Using the advice in this article, you can get your home’s essentials back up and running.
