Curling iron repair - Thyristor diagnosis and replacement - Healing Bench #10

[@19Edurne]

Wish you had shown how to test the thyristor...

[@TasteTheCode]

It usually fails either all contacts open circuit or dead short. Otherwise it has like diode bridge in between.

[@19Edurne]

@@TasteTheCode I wrote that because I've got one that doesn't beep but shows a value (1890) on continuity testing but nothing when I put the multimeter on 2000 Ohms setting. So not being a specialist, I'm a bit puzzled.

[@Blackwolfvideo1]

Very clearly explained, thank you

[@TasteTheCode]

You're welcome!

[@muhammadmughees9869]

which micro controller is used to control the temperature

[@TasteTheCode]

No idea. You can't see it on the video but there is a resin blob under the screen that covers the chip.

[@muhammadmughees9869]

@@TasteTheCode ok thanks

Hello Sir Ikonic crimper machine Eror shows please tell me what fault

[@TasteTheCode]

No idea, I don't own that device.

[@suryaprakash6962]

I am having the same problem in Remington hair curler. It's not heating up. According to your advice, I will change the microcontroller resistance. I'll also let you know later on. Let's see, what happens.

[@TasteTheCode]

I'm not sure how you can change the microcontroller resistance but whatever you do, be careful. The device in question in my case is called s thyristor. It had nothing to do with the microcontroller as it was working OK.

I want vega vhch-04 R2 resister value

[@TasteTheCode]

Sorry, I no longer have this to check the value.

[@arifgulfam2078]

Bro can you give me circuit daigram of this with value

[@TasteTheCode]

Sorry but I do not have it. What is wrong with it?

[@devidasgawade69]

What's is the zener value beside 10 v 100mf

[@TasteTheCode]

Sorry, I can't measure it as I no longer have the iron. I gave it back once I repaired it.

[@arifgulfam2078]

I need its diagram

[@TasteTheCode]

Sorry but I can't help.

[@anaaljazzazy3105]

Mine is a wire that is not funcioning

[@anaaljazzazy3105]

Functioning*

[@TasteTheCode]

That is a typical resistive heating element. Please be careful with it as the mains voltage runs through it.

[@rahulpatelgujratahmedabad3497]

Good tiching 👍👌👍👌👍👌👍👌👍

[@TasteTheCode]

Many many thanks 👍👍👍

[@skittlewee4041]

My curling iron also stopped heating....but i dont have the tools and knowledge to repair the way you shown 😫

[@TasteTheCode]

That's too bad. Check with any of your friends. Someone might be into electronics and can try to diagnose what is wrong with it. Last option is to take it to a repair shop.
