Yes, Panasonic is aware of this faulty product, and has a solution. A chat with tech support today (9-12-2023) said "Yeah, those are symptoms of an internal component failing, unfortunately. Would you like me to look for a service center?" [br]
My microwave, and dozens of other people's (read the unhappy 1 star reviews on Amazon) echo the exact same failure sequence. And they are not happy, because if it is out of the 1 year warranty-- so it's toast. For what I paid (over $350 with tax and shipping) it should have lived longer than 2 years and 6 months!
