Hi my microwave recently made a loud pop and then quit heating everything else seemed fine ,took to a repair shop for 50 bucks they told me I needed a new magnetron and diode for a price of 300 more I decided to repair myself ordered the parts and replaced them, seemed pretty simple.but when i plugged it in to give it a test it came on for about a second then everything shut down no power period.Seems like it has to be a fuse but what would cause this . any help would be grateful.I am determined Thanks Vincehttp://forum.appliancepa...images/smilies/smile.gif

Thanks Gene if capacitor was bad would that cause the no heating and display to go out.when i took my microwave in to have it checked everything worked just no heat then when i replaced mag and diode it instantly shut it all down wondering if the appliance store give me wrong advice i checked the old mag and diode by the directions and both checked fine.would capacitor short the fuses
