First thing was to look on YouTube for the error code. There were dozens of videos pointing to the most common problem: the hall (rotor position) switch. After watching the YouTube video twice, I ordered the switch from Appliance Parts Pros. Received the switch in three days and it took about 15 minutes to make the repair. My sister in-law was ecstatic that she didn't have to pay a repair man. Who knows how much it would have cost. Total cost of repair was about $26.00 and that included shipping.
