Parts for Kenmore 721.66339011 (72166339011, 721 66339011): Interior Parts

This is a truss-head tapping screw used to secure trim, panels, and small assemblies on compatible LG appliances. It provides a low-profile, wide-bearing head that helps hold parts flush and resist pull-through. What it does:

• Fastens plastic and sheet-metal components where a self-tapping thread is needed
• Truss head spreads load to prevent damage to soft or thin materials
• Helps secure control panels, brackets, or trim pieces that require a low-profile head
• Common replacement when original mounting screws are missing, stripped, or corroded

• One truss-head tapping screw

• Use the correct screwdriver bit and moderate torque to avoid stripping the screw or workpiece
• Start threading straight and let the screw form threads without forcing at an angle
• Disconnect power and follow appliance-specific service safety procedures before working internally
• Replace any damaged mating threads or clips for a secure fit

This truss head tapping screw secures panels, brackets, and covers in your appliance. Replacing a missing or damaged fastener restores a snug fit, reduces vibration, and helps keep components properly aligned for reliable performance.

• Provides low-profile holding power; wide truss head helps secure thin panels and trim
• Replaces lost, stripped, or corroded screws at the original mounting points
• Helps eliminate rattling, vibration, or loose handles/covers
• Addresses situations where a screw will not tighten or backs out during use

• Disconnect power; shut off water/gas if applicable before servicing
• Align parts and hand-start threads to avoid cross-threading
• Tighten until snug; do not overtighten to prevent stripping
• If the receiving hole is damaged, for repair before installing the new screw

This thermostat controls refrigerator temperature to help maintain proper cooling and prevent spoilage. It replaces a failed or inaccurate temperature control to restore consistent operation. What it does:

• Senses internal temperature and signals the compressor to cycle on/off
• Helps keep food at steady, safe temperatures when functioning correctly
• Commonly replaces thermostats that cause warm temperatures or inconsistent cooling
• Works as a direct replacement when matching the OEM part number

• Always disconnect power to the appliance before servicing to avoid shock or injury
• Handle the sensor and terminals carefully; avoid bending or damaging components
• Basic hand tools are typically required; follow your model's service manual for exact instructions

The Diode Assembly is an OEM replacement part for LG microwaves. As an electrical part, it plays a key role in regulating power distribution throughout the microwave. 

Symptoms of a bad diode assembly can include:

• Lights or displays failing to illuminate  
• Inability to power the microwave or select cooking functions
• Intermittent or unexpected shutting off during use
• Sparking, burning smells or tripped circuit breakers

Causes may arise from repetitively fluctuating power loads degrading individual diodes over time. Moisture intrusion into electrical pathways can also cause issues.

This genuine LG OEM assembly is also compatible with some Kenmore microwave models as well.
