IS THIS NORMAL?

IS THIS NORMAL ❓ [b] Beko wmb91442lw
To have brown heat markings around a component like a chip. I found this whilst trying to find anything unusual on the pcb.i have a pic but too large to post any ideas? Thank you.

Then resize it, if the image is on a PC then Windows Paint is perfectly adequate for simple resizing.
There are also plenty of simple, free image resizing apps for all smartphones or tablets.

You don’t say why you felt you needed to look at the pcb in the first place?

Re: IS THIS NORMAL?

Ok thanks. Just looking for anything that looks abnormal and cheap to fix.

Resized pic of the component.

Re: IS THIS NORMAL?

The bottom left and bottom right pins do look as though they’ve overheated. Probably looks pretty burnt on the track side too?

Re: IS THIS NORMAL?

Slight discolouration. But this is all new to me. Looking into replacing it as they are so cheap.and checking other components on the board.

I’m deep undercover in enemy territory if you must know.shhh the code, wmb 91442lw no spin…traced to pcb…
May need a VIPER12A PWM SMPS Controller…….info limited…
All else is good….the search continues….

Re: IS THIS NORMAL?

What does the other side of the pcb look like, might just need a spot of solder?

Hey, I`m also behind enemy lines too in more ways than one!
Your machine is fitted with the dreaded Askoll M500 induction motor which is well known as a source of grief. Underneath its plastic cover is a pcboard, all part of the motor, and that is the most likely problematic area. I have to be honest and say I have never replaced the motor as the motor is about £160 which is a robbery price / about half the price of the damn machine.
Your original question ref the chip: 50/50. Have seen this on other pcbs on other makes of machine and there`s nothing wrong. This part is still a suspect though and since it is cheap to replace that first and see what happens.
Back to the motor, there are a few articles written on this on the net but in German and French, have yet to stumble on anything in English but I didn`t spend a lot of time looking to be honest- try youtube? If you type in Askoll M500 Beko motor some stuff crops up.

Re: Askoll m500 motor

Outside of the motor there is an induction coil mounted low down on the back left of machine, on some this goes, I have had a few where when it was changed it sorted the no motor action fault, but to be honest most are the motor that fails
