GE WB27X1160 Microwave Diode

Microwave High-Voltage Diode – GE

The high-voltage diode works with the capacitor to convert AC power to DC, doubling the voltage supplied to the magnetron for microwave generation. When it fails, the microwave runs but produces no heat, or it blows the fuse. This direct-replacement diode restores proper high-voltage circuit operation and heating.
