This was the motor control board (also called the speed control board, motor control unit, or MCU in various places across the web). The repair was straightforward, except for two complications. First the old part was difficult to access in this model washer (Frigidaire Gallery Series front load washer). Instead of being easy to reach on the left side where there was space, it was sort of behind the actual motor on the right side of the housing. I spent some time trying to figure out whether is is possible to remove the side panel of the washer for easier access (I had removed the back panel), but that side appears to be structural, and can't be opened. Only one screw holds the part in place, and after removing this screw it was possible (difficult, but possible) to slide the part under the motor and remove it from through the back panel. There are 4 electrical connections. 3 of them were easy to remove and connect to the new part, the 4th was difficult. This connection is the one where there is a single wire and there is an unusual connection, sort of a large blade with a connector that looks like it should just slide off, but wouldn't. I was eventually able to get it off by loosening a metal curl with pliers, and then squeezed it again after attaching it to the new part. If I had to do this repair again, I estimate it would take 20 minutes, but since I was unsure about what would work and was being cautious about possibly breaking parts or finding easier ways, I spent around an hour working on it. I used a square bit screwdriver to remove the screws on the back panel and securing the part, however, they were all also set to work with a Philips head as well. It wasn't as easy as I hoped, but doing it myself saved quite a bit of money and wasn't actually that hard, in the end.
