A:Answer Yes, I had different problems from the 1st time I used it. Often times the beeping sound would not stop at the end of warming something up. Most of the time the beeping would then turn into a solid tone that would not stop until I unplugged it. If it did stop, it would randomly start beeping again a few minutes after the microwave turned off. A few times after I unplugged it and then plugged it back in, the solid tone would start again without turning on the microwave. I returned it after a couple of days and got another one. So far, no problem with the replacement after 1 month of use.
