T3 Straightener Not Heating Up (7 Ways to Fix)

As a flat iron user, I know firsthand the frustration of dealing with a straightener that is not heating up. I personally faced this issue with my T3 straightener and, after some research, found a few possible solutions that helped me fix it. 

In this article, I will discuss these possible solutions and provide tips on how you can troubleshoot and fix your T3 straightener if it is not heating up.

Let’s get started!

How to Fix T3 Straightener Not Heating Up 

Here are possible solutions that will help to fix your T3 straightener. 

Reset Straightener 

While the above solutions do not fix your T3 and are still not working, you should reset it. Resetting the straightener will return it to the default factory settings.

Because you might have mistakenly configured settings on your straightener, which caused it not to heat up. 

Here are the steps to factory reset the straightener: 

  1. Press and hold the power and refresh mode buttons together. 
  2. Let the buttons go while the straightener turns off. 

Once you have reset your T3 straightener, it will be turned to the factory default settings. And it will start working like a new one. Now you can set up your heat settings and start using it. 

Unlocked Screen 

So, the straightener is turned on but not heating; T3 has a feature it will heat up while the screen is unlocked. It means the straightener is not ready to use, and you are still configuring the temperature or other settings for being started to use it. 

When the screen is locked, you cannot change the straightener settings, temperature, etc. However, you will need to lock the screen to start heating up. 

To lock or unlock the screen, the power button will be used. You can double-tap on the power button to lock or unlock the screen. 

However, the screen will automatically be locked after 10 seconds of inactivity. Once your iron beeps and lights turn solid, the iron has reached heat selection. 

However, reading the owner’s manual will help you understand the straightener features and auto heat settings. 

Use Manual Heat Settings

If you are using your straightener in the HeatID mode, it may not work correctly for your hair. You should try to use the manual mode to adjust your temperature and other settings.  

If for the first time, tap the power button once while the straightener is powered on. You will hear a beep, and then the HeatID icon will disappear. 

Then the heat settings panel will appear. However, if you use this manual mode for a second time, the iron will automatically start heating up to the last used settings. 

Although you can again set up heat settings manually according to your hair type anytime. Here you can check how to change/set up heat settings on your T3

Clean Straightener Plates 

If your T3 straightener is not heating up, one possible cause could be dirty or damaged straightening plates. 

To clean the plates, you must take a few cotton balls and a little rubbing alcohol. 

Dip a cotton ball into the alcohol and gently rub it on the plates. Be sure to pay extra attention to any areas that may be particularly dirty or sticky. 

Once you have finished cleaning the plates, use a clean cloth to wipe away any excess alcohol. 

This will help ensure that the plates are clean and free of any debris that may prevent them from heating up properly. 

If cleaning the plates does not resolve the issue, you may need to consider other potential causes or seek assistance from T3 customer service.

Tool is Unresponsive

As discussed above, the locked screen will make your device unresponsive, and you will not be able to configure any settings. 

If your straightener becomes unresponsive, the simple method that you should try is to ensure that the screen is unlocked. 

While the screen is unlocked, the straightener will stop heating up, and now you can change any settings.

To lock or unlock the screen, quickly double-tap the power button. And you will hear a sound to indicate the screen is unlocked. 

And if your straightener is still unresponsive the other way you should try to unplug the tool from the power source and wait about 15 seconds. And then plug in to check if the tool is now responsive. 

Not Turning On, use Correct Way. 

You have bought a new T3 straightener, and it is not turning on; the first thing you should notice is that you are trying to turn it on correctly. Firstly ensure the straightener is securely connected to the power source. 

And then, if you want to turn your T3 power on, the correct method is to press and hold the power button for about 3 to 5 seconds; until you feel a vibration. 

After this, the straightener will be turned on and brought to the HeatID mode. And the screen will be unlocked; the HeatID icon will light up and start blinking to input your hair profile. 

Power Button Not Visible 

Another issue most users have been facing is that the power button is not visible on the straightener. This will be frustrating because you can not turn your straightener powered on. 

So, here are a few steps that you should try to fix this issue.

Firstly check if the straightener is properly plugged into the power source. If it is not getting enough power, the button will not appear. Unplug and replug the straightener into the power source to check if the straightener lights up. 

And the second way is to unplug the straightening tool from the power outlet and wait about 15 seconds. After this, plug into the power source and check if the issue is fixed. 

Additionally, check the power supply, including the power outlet and power cable of the straightener. You will face this issue if the power cable or the power source is faulty. 

You can check the power source by plugging in another device, such as a lamp. If it does not light up, the power source is faulty, and you should plug your straightener into another power source. 

Replace T3 

If your T3 straightener is not heating up, one potential solution is to replace the straightener. T3 offers a product warranty for 24 months from the date of purchase.

 However, this warranty does not cover damage due to misuse or abuse, such as incorrect voltage supply, dropping the straightener, or failure to follow the enclosed instructions. 

It also does not cover tampering, such as attempting to repair the straightener. If you believe your T3 straightener is covered under warranty, call (866) 376-8880 for assistance.


In conclusion, if your T3 straightener is not heating up, you can try a few possible solutions. These include checking the power source and cord, ensuring that the straightener is properly plugged in, and cleaning the heating plates. 

If these steps do not resolve the issue, you may need to contact customer support or replace the straightener.
