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.

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?
