Genuine Samsung part.

Cross Reference Information

Part Number DE81-06784A replaces AP7029147, 66676.

Description

This high-voltage diode assembly converts the microwave oven's high-voltage AC into the DC needed by the magnetron so the appliance can produce heat. Replaces a failed diode to restore normal heating performance. What it does:

• Converts high-voltage alternating current to direct current for the magnetron.
• Commonly linked to no-heat or weak-heat symptoms when the diode fails.
• Can cause blown thermal fuses or visible arcing if shorted.
• Works as part of the oven's high-voltage circuit alongside the capacitor and transformer.

What's included:

• One high-voltage diode assembly

Install notes:

• Always unplug the appliance before servicing and discharge the high-voltage capacitor before touching components.
• Handle with insulated tools and avoid contact with capacitor terminals; high voltage can be lethal even when unplugged.
• Inspect the high-voltage capacitor and fuses when replacing the diode; replace any damaged parts to prevent repeat failures.
