Hi, to one and all,
First of all, thank you for replying to my thread. I am very grateful for any help in this matter.
The reason why I was asking for information on a shop or firm that might be able to help me replace this 40+ year capacitor. Is because I have a basic understanding of electronic. So if I could have got the exact replacement, it was a straight forward case.
Years ago we had small stores in this country where the owners were really into electronic as it was there hobby as well as there livelihood. They were not just sales people, like you get in the stores nowadays, who just know what a component looks like, but they do not know what it does.
I will now tell you the full story, a couple of weeks ago I purchased a 2nd hand Singer sewing machine, being sold for spare’s or repair’s. The lady who I purchase it from, said that she thought that the motor needed servicing?!.
When I got it home and plug it in, I switched it on, the light came on first of all, then a few seconds later the machine started working. By it self!, with out me having to press the electric speed controller. I could also smell a burning smell at the same time, so I switch the machine off, and opened the electric speed controller. I found a capacitor in it, that had ruptured. A picture of which I have enclosed, it is the 0.1 uf, I have also sent a picture of the inside of the speed controller.
You will see that I have replaced the ruptured capacitor with a replacement, that I purchased from a company in this country called “RAPID” I sent them a photo of the capacitor, they in turn came back and said that this was the closes they had. I have sent a photo of it as well. The information printed on the pack states the following, Suntan TS08V0A9104KBB0D0R 0.1 uf + - 10% 310VAC x2 mini polyprop Film capacitor.
When I had installed this replacement, I again switched the machine on, this time when the light come on, and a few seconds had past, and the machine did not start of its own accord. I pressed the electric speed controller, and the machine worked as it should do. So I ran the machine back and forth speeding up slowing down, and then stopping, to smell the air just in case there was still a problem. I must admit that I was feeling very pleased with my self. But then there was the sound of crackle’s, and sputter’s, then pop, then smoke poured from the machine. So I switch it off, and open it up, to find out what had burn’t up, the motor looked alright. So I opened up the electrical connection box inside the machine, and found that there was another capacitor there,(0,22uf) that had now ruptured. Which you will see from one of the picture is linked in parallel with a resistor.
So there are a few question to be asked, did the new replacement capacitor cause the other capacitor to rupture?, or should the first question be, what caused the capacitor in the electric speed controller to rupture in the first place. This is why I think the lady who sold me the machine said that she thought that the motor needed servicing because she had smells a burning smell, and thought it was the motor. But the burning smell had been coming from the cracked capacitor in the electric speed controller. I did look on the internet to see what could cause a capacitor to rupture, and it mention an over voltage situation.
Any thoughts on what I have informed you, would be much appreciated
