I bought the control board from Appliance Parts Pros. It arrived really fast and my husband replaced the part in probably 15 minutes or less. I don't know what it is, but my appliances go out around the holidays every year! Have had to replace a stove and a dishwasher between Halloween and Christmas the past two years, and I'm on my fourth refrigerator in three years! Wish I had known about Appliance Parts Pros a lot sooner; I would have saved many hundreds of dollars!
