The GE appliance technician replaced the magnetron, HV capacitor, and diode without luck but only charged me the service call, not for the rest. He however told me the only item left would be the HV transformer. Having watched the nearly 2 hour teardown and rebuild for the parts, it gave me the knowledge needed to attempt the HV Transformer. Having received the transformer, I tore into the micro removing the old TF. To my dismay, the old TF tested good (per advice from the internet checking the prim and sec resistance values... they also came close to the new TF. So I elected to dig out the schematic and troubleshooting flowchart hidden inside my micro. All things led back to a door switch which checked bad... part which I didn't have. Reassembled micro, ordered switch from Parts Select and installed in about 1/2 hour. Micro work great now. Only if the GE tech would have followed the flow-chart! I ended up returning the HV Transformer since it wasn't used and not needed. Had to absorb shipping costs.
