If your curling iron is not turning on, the first thing to check is the power source. Plug it into a different outlet to rule out a dead socket. If that does not work, inspect the cord for visible damage and ensure the power switch is not stuck in a locked position. Many curling irons also have a safety auto shut off feature that may have been triggered, or a reset button if it overheated. These simple steps resolve most cases of a curling iron not turning on, so start there before assuming the iron is broken.
1. Dead Outlet or Loose Connection
The most common cause is a faulty outlet or a loose plug. Try plugging the curling iron into a different outlet, preferably one that you know works with another device. If the iron lights up, the original outlet is the problem. If the cord is loose in the plug, the connection may be intermittent, causing the iron to act as if it is not turning on.
2. Damaged Power Cord
Inspect the entire length of the cord for cuts, fraying, or bent prongs. A damaged cord can break the electrical circuit, preventing the curling iron from turning on. Look for any exposed wires or kinks, especially near the base where it connects to the iron. If you see any damage, stop using the iron immediately and replace it, as this is a fire hazard.
3. Auto Shut Off or Safety Timer Engaged
Many modern curling irons have an automatic shut off feature that turns the iron off after a period of inactivity, often 30 or 60 minutes. If your iron is not turning on, it may have triggered this safety mode. Unplug the iron, wait 10 seconds, then plug it back in and try again. If the iron still does not turn on, check for a dedicated reset button. Some models require you to press a reset button before the iron will heat again.
4. Overheating Protection Activated
If the curling iron got too hot, an internal thermal fuse may have tripped to prevent damage. This is different from the auto shut off. The iron may need to cool down completely before it will turn on again. Let the iron sit unplugged for at least 30 minutes. If it still does not turn on after cooling, the thermal fuse may have blown permanently, which requires professional repair or replacement. For more on overheating issues, see our guide on hair styler overheating.
5. Stuck Power Switch or Lock Button
Some curling irons have a sliding power switch that can get stuck in the off position, or a travel lock button that prevents the iron from turning on when engaged. Check the switch for any debris or gunk that might be blocking it. If the iron has a lock or safety button, slide it to the unlocked position. Sometimes a gentle press of the switch can dislodge a stuck mechanism.
6. Internal Electrical Failure
If none of the above steps work, the curling iron may have an internal electrical failure, such as a blown fuse, broken heating element, or faulty wiring. This is less common but possible, especially in older or heavily used irons. Unfortunately, this type of problem is usually not repairable at home. If the iron is still under warranty, contact the manufacturer. Otherwise, it is time to replace it.
How to Fix a Curling Iron That Won’t Turn On
- Test the outlet with another device to confirm it works.
- Inspect the power cord for visible damage and replace the iron if found.
- Unplug the iron, wait 10 seconds, and plug it back in to reset the auto shut off.
- Let the iron cool for 30 minutes if it may have overheated, then try again.
- Check the power switch for debris and the travel lock for engagement.
- If none of these work, the iron likely has an internal failure and should be replaced.
If your curling iron has a burnt smell or shows signs of scorching, that may indicate a more serious electrical issue. Our guide on why your hair styler smells burnt can help you identify the cause and decide whether to repair or replace the device.

- Produces consistently beautiful, salon-quality curls that last longer
- Safe, burn-proof design makes it perfect for teens and beginners
- Available in multiple barrel sizes to match different hair lengths and textures

The TYMO CURLPRO is an automatic rotating curling iron designed for anyone who struggles with traditional wands or wants effortless, professional-looking curls. Whether you're a teenager learning to style hair, someone with fine and thin hair that won't hold curls, or simply tired of burning yourself, this tool delivers results without the frustration.
The standout feature is the automatic rotating barrel that does the heavy lifting for you. Instead of manually wrapping hair around a hot barrel, you simply feed sections into the chamber and let the rotation handle the curl formation. Real users report creating full heads of beautiful waves in just 5-8 minutes, with curls that last for days. The cool-touch exterior is genuinely protective, eliminating the common issue of burning your ears or scalp while curling back sections.
Build quality is solid, with multiple barrel size options (1 inch and 1.25 inch available) to accommodate different hair lengths and thicknesses. The device features three temperature settings for customization based on your hair type, and an audible beep notifies you when each curl is complete. The design is intuitive enough that even people who've never successfully curled their own hair report immediate success.
The main consideration is that despite being easier than traditional wands, there's still a modest learning curve to master the technique and get consistent results. Additionally, the device is larger and heavier than standard curling irons, so it requires more counter space. Some users also note that maintaining curls overnight requires loose bun styling to preserve the wave pattern.
The TYMO CURLPRO is an excellent investment for anyone seeking fuss-free, beautiful curls without the skill requirements of traditional styling tools. The combination of speed, safety, and consistent results makes it a standout choice in the automatic curling category.
Teenagers learning to style their own hair for the first time will appreciate the ease of use and safety features that prevent burns during the learning process.
People with fine, thin, or slippery hair that refuses to hold curls will find that the CURLPRO's automatic rotation creates lasting waves where traditional methods fail.
Beginners and non-coordinated stylists who've struggled with manual curling irons will finally achieve salon-quality results without frustration or injury.
Anyone with longer hair seeking to cut styling time from 20-30 minutes down to under 10 minutes will love the efficiency of this automatic system.
