I am very disappointed with the loud frequent buzzing that occurs during drying. I have read reviews and clicked on numerous links that describe "normal" sounds, but have yet to find a suitable example or explanation for the sound. The service person that installed it stated that the buzzing was the heat sensor. If so, it is a significant distraction to hear throughout the drying cycle. As our home has limited space for a washing unit, we are relegated to living with it, but it is terribly disappointing.
