Componant ID……

[Mark(IOM)]

Hello troops,

Can someone please identify the componant in the picture for me please. It came out of a Whirlpool AWO/D 4605 Washing Machine which although had power to it, was not responding to any programme etc. I checked the PCB, and found this to be damaged.

Thanks a lot.

Re: Componant ID……

well we know its probably a resistor what i cant make out are the coloured rings this is how you will get the value

have a good look at it try to detemine the colours your looking for

black, brown, red,orange ,yellow,green,blue violet grey white

then put them here

Re: Componant ID……

I’m fairly certain there is a thread or two concerning this very problem and identifying the component….
the site is going so slow for me that i have given up searching for it, but i’m sure it is there somewhere

Re: Componant ID……

Thanks guys… I found the thread you were talking about Chezza, and the content is similar to my problem.
I make it a 470ohm resistor with a 5{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} + or – on the link Dave sent. The colours on the resistor look like – Yellow – Violet – Brown – Gold. Seems high ohm’s compared to what the guys were dealing with on the thread mentioned by Chezza though !

Re: Componant ID……

Have you tried to see if it’s actually open circuit? They can sometimes look like that and still retain correct value. Might be what was in line with it that’s to blame for the fault.

Re: Componant ID……

Thanks Mike, no, it isnt open circuit, it gives a reading of 0.8 ohms, so I thought that although it was not open circuit, it was not up to its correct value and that was why the machine might not be not operating..? I have checked the in line components visually, and all look ok.

Re: Componant ID……

Kind of strange for a resistor to go what is practically short circuit. I wonder if you got the number of bands right. There are sometimes 4 + the tolerance with certain types.

agree never known a resistor to go down in value only up

Re: Componant ID……

Mmm, I have to say, sometimes the bands are not so easy to make out re the colours etc. I thought someone might recognise the one I have posted. On my calculation, I make it a 470ohm resistor. I was hoping to try a repair. It is a scrapped machine, and w ould be a good project to try.

Re: Componant ID……

It sounds like its more likely to be a 470 uH inductor (choke) in which case the meter reading is probably correct.

Re: Componant ID……

any chance of a pic of the pcb ? and the resistor component number might have an old timer knocking about so can tell you exactly what its supposed to be

Re: Componant ID……

Just a reminder. Before measuring values of a component (eg resistor), you need to unsolder one leg out of the pcb before measuring. This is because your meter can be reading through other components on the board,giving a false reading.

Re: Componant ID……

Thanks for your replies all, I have attached some pics of the PCB. The suspect piece came out of the location marked L003 on the PCB. I made the measurement when I had taken the resistor off the board, and the pic of it is at the top of this thread. I am starting to get a little concerned when ‘Chokes’ are mentioned..! :eeek: Not looking as straight forward as I had hoped.. ❗

Re: Componant ID……

When circuit boards are marked “L” is used as the type mark for an Inductor (choke), if it was a resistor then it would be an “R”.

I don’t know the board in the picture but I would quickly check that “R020” is not open circuit as that looks like a fusible resistor – Do you get any life from the display or is it completely dead?

colours yellow,violet, orange, gold inductor value: 47 Millihenrys +/- 5 {e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}
