Sorry for resurrecting an old thread, but I need help with one of these.
Same type of washer, same board, different failure. With my motor control, the fusible link traces near the mov had vaporized. Also, one of the 3 components leading from ground to the motor control has vaporized. Further troubleshoot revealed a shorted phase in the control chip, a low side transistor shorted source to ground.
I found the datasheet for the chip, and it looks like the component is a current sense shunt for a phase of the motor. They're pictured previously and are little rectangles with a Chevron in the middle.
My burning question is what are these components? I did a resistance check and the two that are good measure about 3k ohms and diode check both ways about 1.4 volts with my fluke meter.
