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.appliancepartspros.com/images/smilies/smile.gif

Hello,

Possible the high voltage capacitor (#2 at the diagram) is shorted out. Open the control panel to access the capacitor and the fuse.

Discharge the capacitor and check it for continuity.

- The high voltage capacitor Part number: 5303319549

Part number: 5303319549



- The fuse kit (included the monitor switch) Part number: 5303319559

Part number: 5303319559



Here are the breakdown diagrams and Parts for Frigidaire PLMVZ169GCB Microwave - AppliancePartsPros.com

Gene.

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

If the capacitor is open then the microwave would not heat.

If the capacitor is shorted then it will blow the fuse.
