I heard my refrigerator for the first time last night while laying on the floor playing with the dog. It is the only time I have heard it. But the freezer is totally packed with 75 pounds fresh caught salmon and tune that we bought fresh off the boats the other day, so I figured it was really working. Today, I have not heard it.
I also had the earlier voodoo microwave replaced and the new one is working perfect. It baked homemade wild blackberry cobble to perfection. I didn't know there were any problems with the new models.
