Sewing Machine Foot Control Pedal. What's inside an Electronic Foot Pedal 

Thank you for this video! You just saved me $50 on a new foot pedal. The little white sliding thing had popped off and I didn't know how to put it back on... and then I did! Thanks again!

The most common trouble of theese pedals is the failure of triac BT136 or BT138. If so, pedal does not regulate the speed of motor, and it starts to rotate at maximal speed on any working position. The triac costs less then 50 cents, so it's very easy to remove it and solder the new part instead of broken one. Also it's easy to improve this pedal. Small carbon resistor R3 is installed instead of trimmer resistor. It sets the minimal rpm value (the initial speed of the motor). If your motor starts to turn too quickly, just increase this resistor (desolder it, measure its resistanse, and solder another resistor twice as much or so instead), or remove it, and solder on its place a trimmer resistor about 1-2.2 MOhm (it could be quite difficult to buy). The bigger its resistance, the less speed the motor runs on first movements of pedal. For example, I had to increase it up to 1 MOhms, and the initial speed of the motor became about 1000 rpm. Maximal rpms remained to be the same, this resistor does not affect it. Of cource one shoud do it on his own risk and must understand what and how to work with such a device. And never open the lid with the plug inserted in mains.

Bless you for this video!!! My foot peddle broke open with a large spring and I was so confused where it went till I saw this video. You definitely saved me money and time getting someone else to fix this simple task.

muchas gracias Dios la bendiga siempre

Great video

Life saver

Are these a viable replacement for the carbon pile old-style pedals?

For these electronic foot pedals, does it matter which wire is positive and which is negative if I were to hard-wire it?

Hi Tanks so much for the demo....is the same pedal used with SINGER 6180 machine?, if not, can you kindly show us the foot pedal of the SINGER 6180 machine. Thanks

Do you know How to repair a Singer brilliance Power board? I need to change one pieces, but i can't find a good pictures with instructions.😥

Thank you for this video. Can you please advise what lubricant is used on the sliding mechanism? Is it some sort of silicone-based product?

yo tengo de ese pedal pero se me cayó y ahora cose lento a que se debe mucho agradeceré su ayuda

Thanks ! my machine´s pedal contains only a variable resistance, a track plate, not a rheostat, i mean, it's the simplest thing ever and i guess i might replace it with just a fader, that slider variable resistance component... what i'd like to know is the value it has to be considering it's 220v ( i guess ), thanks !

So, desolder everything except the slide pot, mount a stereo audio jack in the hole where a wire comes out with wires going to the pot, and use it as a synth pedal?

Hi...you could break the fuse when removing it that way. Try a narrower blade screw driver on one of the ends.

Thank you so much Please support our Channel

Mine has no fuse, two extra yellow 250v bricks

How much current does it use per hour

My singer Merritt electric sewing Machine is running without pressing pedal.please let me know how to repair it by myself.... rply me please

There's a fairly good explanation of how these work here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-quetOZsITJA.html The one you have here has a little more filtering (mostly back EMF suppression), but it's fundamentally identical to a dimmer switch. Quite easy to repair actually.

Is this a 250 volt unit?
