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 rectifier converts incoming AC power to DC for the appliance's control circuits, restoring correct electrical supply to electronic components so controls and powered features can operate properly. What it does:

• Converts alternating current (AC) from the mains to direct current (DC) used by control boards and electronics.
• Restores power to electronic controls, displays, and powered dispensers when the rectifier has failed.
• Common symptom: control panel, dispenser, or ice maker loses power or becomes unresponsive.
• Needed when intermittent electrical problems occur that trace to the power-conversion stage.

• One rectifier (single part as sold)

• Disconnect power to the appliance before attempting any service to avoid shock hazard.
• Handle the rectifier and control boards carefully; avoid static discharge and physical damage.
• Verify fault with a multimeter and wiring diagrams or service manual before replacement.

This diode is a small rectifier used on the appliance control electronics to allow current to flow in one direction, protecting the board and enabling proper control signals. Replacing a failed diode restores correct circuit behavior. What it does:

• Provides one-way current flow on the control board to prevent reverse voltage
• Protects sensitive electronics from backfeed and voltage spikes
• Can prevent control errors caused by a shorted or open diode
• Commonly replaced when control circuits fail to power or behave intermittently

• Disconnect power to the appliance before accessing controls to avoid shock
• Handle circuit boards and components with ESD care; avoid touching traces and contacts

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
