Product Details

Genuine Samsung part.

Cross Reference Information

Part Number 0401-001002 replaces AP3998685.

Description

This high-voltage diode replaces the microwave oven diode that works with the HV transformer and capacitor to provide power to the magnetron, helping the oven produce heat. Use this exact-fit replacement when the diode is damaged. What it does:

• Converts the transformer's AC into the DC needed by the magnetron
• Helps maintain the high-voltage path for normal heating operation
• Common symptoms of a failing diode: microwave runs but doesn't heat, blown cavity fuse, or visible burning/damage on the diode
• Works as part of the high-voltage assembly with the transformer and capacitor

What's included:

• One replacement high-voltage diode

Install notes:

• Always unplug the appliance and discharge the high-voltage capacitor before servicing
• Handle high-voltage components carefully; wear insulated gloves and use insulated tools
• Replace with the same orientation and secure all connections; inspect surrounding components (fuse, capacitor) for damage
