Butch L Hensley , AR November 09, 2020 Appliance: Model KENMORE ELITE MICROWAVE MODEL 72179203010 Microwave would run with door open. I repaired it by replacing the lower door switch and the micro switch just above the lower door switch. The top door switch wasn’t replaced. Total time to repair took about 45 minutes.
