Question about Neff H7871N2GB Convection / Microwave Oven
Found blown 10a fuse blown on display pcb.Replaced fuse but found blown diode on mircowave power supply.Dose this mean the microwave unit is blown or is it worth replacing the diode and where can i get a replacement.Dose anyone have a service manual for this machine.
If the diode failed by opening, there may be no other damage. If the dioded failed by shorting, the alternating current may have damaged other components. Ohm it out. You can get diodes from digikey.com, mouser.com, or radio shack or any electronics or appliance supply. If the diode is charred and you can't get the part number, the oven rating can be used to select a replacement. Since the fuse was 10 amps, the diode should also handle at least 10 amps. If you can power the unit and read the voltage at the diode input this will give you the power (volts times amps). It's always worth trying as it's cheaper than replacing the unit.
