The warranty is 2 years but I have yet to see a 6091 just go out, they typically fail from getting wet or a break in the cord. The most common water damage being water entering the foodtimer button from being touched with wet fingers. Waveboxes made in the last 3.5 years have no alarm, that was a fairly old feature. Send it in and I am happy to check it out.
