The refrigerator repair guys have come and gone and it turns out they did not have all the parts needed to repair the refrigerator after all! They replaced the compressor and motherboard, plugged it in and sparks flew, which is (they explained to Julie, who explained it to me) bad.
Recapping: This morning our main refrigerator was not working. Now it’s not working and there’s solder powder all over the kitchen, which Julie, bless her, is cleaning up.
