I have a model ME21K7010DG microwave that is approximately 2.5 years old. Shortly after purchase the unit began randomly beeping and displaying the #7. I was told this was a known issue and the door was replaced under warranty. Not long after the warranty expired the unit began the same problem. Now, the unit also randomly turns the fan on. This is a dangerous product as it is unsafe for any any product to turn itself on spontaneously when no one is around.
I am being told that Samsung will not stand behind the product because it is no longer under warranty. Shameful.
