Samsung 72169-406-100 Diode (High-Voltage) OEM Part

Product Details

Genuine Samsung part.

Cross Reference Information

Part Number 72169-406-100 replaces AP4091549.

Description

This high-voltage diode directs and converts the microwave's HV circuit current so the magnetron can produce heat. Replacing a failed diode restores correct high-voltage flow and helps resolve heating problems. What it does:

• Converts and directs high-voltage current in the magnetron circuit
• Helps enable the magnetron to generate microwave energy for cooking
• Commonly linked to no-heat or weak-heat symptoms
• Can cause blown fuses or arcing when failed

What's included:

• One high-voltage diode

Install notes:

• Disconnect power and verify the capacitor is fully discharged before servicing
• High-voltage components can be lethal; use insulated tools and observe safety procedures
• Test related components (capacitor, fuse, magnetron) if symptoms persist
