EXPHV10 Microwave High Voltage Diode
XPARTCO EXPHV10 Microwave High Voltage Diode
The XPARTCO EXPHV10 is a universal aftermarket replacement high voltage diode (rectifier) compatible with most major microwave brands including GE, Whirlpool, Maytag, Samsung, LG, Frigidaire, Panasonic, Sharp, KitchenAid, and Kenmore. The high voltage diode is a critical component in the microwave's high-voltage circuit, working alongside the high-voltage capacitor and transformer to convert alternating current (AC) to direct current (DC) — providing the high-voltage DC power required by the magnetron to generate microwave energy and heat food.
When the diode fails — due to electrical surges, overheating, or normal wear — the magnetron cannot receive the correct power supply, resulting in a microwave that runs but does not heat. A failed diode may also cause the high-voltage fuse to blow repeatedly. Rated at 12,000V DC (12 kV) with a 500mA current capacity, the EXPHV10 is a universal cross-brand replacement that meets or exceeds OEM specifications across hundreds of microwave models.
Quick Answer
The XPARTCO EXPHV10 Microwave High Voltage Diode fixes microwaves that run but produce no heat, have a repeatedly blown fuse, or have a humming sound with no heating. It converts AC to DC power for the magnetron and is rated 12,000V DC / 500mA. Universal fit — compatible with most GE, Whirlpool, Maytag, Samsung, LG, Frigidaire, Panasonic, Sharp, KitchenAid, and Kenmore microwaves.
Common Problems This Part Fixes
- Microwave runs (turntable spins, light works) but does not heat food

Frequently Asked Questions
Will the EXPHV10 fit my microwave?
The EXPHV10 is a universal replacement diode compatible with most GE, Whirlpool, Maytag, KitchenAid, Samsung, LG, Frigidaire, Panasonic, Sharp, and Kenmore microwaves. Use the model search above to verify, or contact our support team before ordering.
What does the high voltage diode do?
The high voltage diode works with the capacitor and transformer to convert AC power to high-voltage DC power — typically around 4,000 to 5,000 volts. This DC voltage powers the magnetron, which generates the microwave energy that heats food. A failed diode prevents the magnetron from receiving proper power, resulting in a microwave that runs but does not heat.
How do I test if my microwave diode is bad?
After safely discharging the capacitor, use a multimeter set to the diode test mode. A good diode will show continuity in one direction and no continuity in the other (one-way electrical flow). A bad diode will show either no continuity in both directions (open) or continuity in both directions (shorted). A shorted diode will also cause the fuse to blow repeatedly.
My microwave fuse keeps blowing — is the diode the problem?
A shorted high voltage diode is one of the most common causes of a repeatedly blown microwave fuse. When the diode shorts, it draws excess current which blows the fuse. If you replace only the fuse and it blows again immediately, test the diode and capacitor as well before replacing the fuse again.
Is this an OEM or aftermarket part?
This is an aftermarket universal replacement part built to OEM-equivalent electrical specifications. It is not a genuine OEM part from any specific brand, but is rated at 12,000V DC / 500mA — meeting or exceeding the requirements of most microwave high-voltage circuits.
