Panasonic Inverter Microwave Oven Schematic request
Greetings,
I am experimenting with the inverter board from the Panasonic NN-H665BF microwave oven (part no. F66456G01AP) in an effort to convert it from constant power to constant voltage and reduce output noise, ripple, and voltage to 2kV. I have the schematic for a somewhat similar Panasonic oven, the NN-G62BH, but there are big differences, especially that my oven inverter uses only a single IGBT driver, has no current transformer and uses a very different control IC. In a web forum, a poster mentioned having schematics for these ovens on a 'Panasonic Service Manual CD' but I have not found any other reference to this online. Does anyone have a schematic or could point me to a source (the Panasonic website only shows 'Instruction Manuals' which are users' guides.)? Hopefully I can save the many hours required to trace the PCB. Thanks, Michael |

It's because most users don't want them repaired and if you don't know how a microwave works, then you have no business being inside of one. |
