Mike T Colombus , NE June 16, 2014 Mirowave ran but the magnetron would not funtion Found one of the interlock door switch springs had a crack in it, but was not noticeable. After alittle trial & error found a door switch not fully made. Looked up the whirlpool microwave model number on the computer. Microwave part pictorial sections were shown. Called APPs operator who was very nice & helpful. Correct whirlpool part was ordered & received the NEXT DAY. I am satisfied with quick service & price.The microwave is back in service.
