The control unit on my Maytag model #MFF2557HEQ went out 4 days ago. Since I was unsure how to diagnose the problem, we called the repairman in. He is ordering the $95 dollar part and installing it for another $155 (2 house calls plus labor) for a total of $250. Makes me wonder since I saw the above post if there is a quality problem? My refrigerator just turned 3 years old.
