Mates bread maker stopped working so I had a look inside and saw this burned resistor.
I’m guessing the heat changed the colors a bit so wondering if anyone has experience in reading cooked resistor values.
I removed it from the PCB and measured it at 403 Ohms.
Thanks for any help.
Thanks! I’ll try replacing it with a 490 ohm resistor and see if it works again.
The element in the bread maker looks like it came loose a bit and made slight contact with the internal metal housing. I wonder if that caused the resistive element to sink more current than the PCB was designed for, burning out the resistor.
That sounds like a possible fail state. Also shitty design. It should use a resettable thermal fuse or something to detect faults without parts burning.
Consider maybe adding a fuse to the design?
You’ll need a fairly high wattage resistor. That one looks like maybe 1W but it might be more.
