Question about Panasonic NN-H644WF Microwave Oven
What causes inverter to fail again . Unit runs for 3 or 4 seconds & inverter buzzes at brushes . Is their another part causing this or was part bad from parts store ?
The magnetron may also be bad, or if there were any weak or inadequate solder joints on the board, that can cause some pretty spectacular failures.
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:
(continuity can be good even though it is bad!)
