Microwave less than 2 yrs old. Barely out of warranty by days we had to replace the magnetron. So disgusted with whirlpool but thta is another discussion. It is now beeping intermittently for no apparent reason. Microwave working otherwise. We have tried to reset the filter, thinking perhaps it was a notification beep. Nope. We unplugged it and waiting 30 minutes and plugged it back in. Still beeping. Turned off sounds thinking it might stop the beeping. Nope. I am afraid I have a lemon and Whirlpool does not give a flip nor did they when it was by 3 days out of warranty. Anyway, any ideas for a disgusted consumer?
