Conclusion
If the Cook light comes on, make sure that it turns off when the rice is done cooking. If all is well, enjoy your meal.
You might well ask how I knew to replace the microswitch. The short answer is that at the beginning I didn't know that was the problem. It was pretty obvious to me that this internal switch played an important role in the device operation, and I knew from past experience that connectors and switches are often points of failure.
Once I got my multimeter probes on the switch and saw that it wasn't working, I knew that I was onto something. In theory there could be more than one thing wrong (one failure can cause another) but this rice cooker is so simple that I was confident that repairing the switch would fix the cooker.
