Genuine Electrolux Zanussi Microwave Oven High Voltage Diode Part # 5550428022

Genuine AEG Electrolux Zanussi Microwave Oven High Voltage Diode 5550428022

Genuine high voltage diode from Electrolux Group, used in the high voltage circuit of a microwave oven. The diode converts the alternating current from the transformer into direct current, which allows the magnetron to generate the power needed to heat your food.

If your microwave has stopped heating properly, is making unusual noises, or has tripped a fuse, a faulty high voltage diode is a common cause and a relatively inexpensive part to replace compared to a new magnetron or transformer. This component is supplied as a single item and is a straightforward part to fit for anyone comfortable working inside a microwave's high voltage section. Before ordering, check the part number on the diode you are removing against the one listed here to make sure it is the correct match for your appliance.

Key Compatibility:

Manufacturers reuse the same part across many models and change model numbers between production runs, so the safest check is your own model number rather than the brand. Enter it in the checker above and we will confirm against this part.
If you are unsure, message us with your full model number and we will confirm before you order.

Expert Installation Tip: High voltage capacitors inside microwaves can hold a dangerous charge even after unplugging, so always discharge the capacitor safely before touching the diode or any surrounding components.
