General Electric Range / Cooktop / Oven Diode Or Rectifier

The High Voltage Diode is an OEM part for GE microwaves. This high-voltage diode is crucial for converting alternating current (AC) to direct current (DC), enabling the magnetron to generate the microwave energy needed for cooking. Measuring approximately 3-1/2" in length, this diode features a banded side with a #8 ring terminal and a non-banded side with a 1/4" female quick connect.

You should replace the diode-H.V assembly if it becomes faulty due to electrical issues, wear and tear, or physical damage. Continuous exposure to high voltage can cause the diode to deteriorate over time, leading to malfunction.

Symptoms of a bad diode-H.V assembly include:

• The microwave not heating food
• A burning smell or unusual noises during operation
• The microwave shutting off unexpectedly
• Visible damage or burn marks on the diode

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

This high-voltage rectifier diode is used in the microwave's high-voltage circuit. It converts AC to DC so the magnetron can produce heat. A failed diode can cause no heat, loud humming, or a blown fuse when starting. What it does:

• Rectifies high-voltage AC to DC to power the magnetron
• Blocks reverse voltage in the HV circuit
• Common failure symptoms can include: runs but doesn't heat; loud hum then shutdown; line fuse blows at startup

• 1 high-voltage diode

• Unplug the microwave and properly discharge the high-voltage capacitor before servicing—dangerous voltage can remain even when unplugged
• Match diode orientation/polarity to the original and ensure a solid chassis ground connection where used
• Route leads and reinstall any clamps/insulators exactly as found; keep wiring clear of sharp edges and hot components
• If the original diode failed, inspect the HV capacitor and transformer for related issues before reassembly

This resistor is the replacement electrical component that restores the correct resistance in the appliance's control circuitry, helping the unit regulate current for proper operation. It's a direct-fit replacement when the original resistor fails. What it does:

• Limits and controls electrical current in the affected circuit to protect and regulate connected components
• Helps maintain correct operating conditions for heating or control assemblies that rely on precise resistance
• Common symptom: appliance exhibits intermittent operation, blown fuses, or failure of the associated circuit
• Can be used to replace a damaged or open resistor that shows no continuity

• Disconnect power at the breaker or unplug the appliance before any service
• Handle the resistor carefully; avoid stressing leads or terminals
