Our lasted maybe two years??
Programmed to work exactly 2 years then components reaches end of life so that you have to replace it with a new one.
Bought it 3/19/19 and malfunctioned 4/27/20. Lasted a whole 14 months. Fan continues to run and interior light is on while door is closed, only way to stop it is to unplug the fan. My previous microwave lasted 9yrs! Kmart/Sears customer service has no sympathy. This was a $219 microwave. WHAT.A.WASTE. Going to my local home appliance store now to purchase a new one...especially since Kmart and Sears no longer exist where I live! Never will be Kenmore again.
