Parts for Lg LTM9020B / AB1ELGA: Section 4 Parts

A Tap-Tite binding-head screw used to fasten appliance panels and components where a self-tapping metal thread is required. Replaces missing or damaged fasteners to restore secure assembly and reduce vibration or rattling. What it does:

• Creates its own mating thread in thin sheet metal for a secure hold without a nut.
• Holds panels, brackets, and trim in place to prevent looseness or movement.
• Commonly used where stripped, missing, or broken screws cause rattling, misalignment, or parts that won't stay attached.
• Compatible with standard screwdrivers or nut drivers sized to the binding-head.

• Disconnect power and unplug the appliance before working on it.
• Use the correct driver bit to avoid cam-out or head damage.
• Start straight and apply steady pressure; avoid overtightening to prevent stripping the formed threads.
• If the original hole is badly damaged, assess for repair or use of a larger fastener as needed.

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 magnetron is the high-voltage microwave tube that generates the microwave energy used to cook and reheat food in your oven. Replacing a failing magnetron restores heating performance when the rest of the microwave system is functioning. What it does:

• Generates microwave energy that heats food inside the oven cavity
• Common symptom: unit powers on but does not heat
• May also cause loud humming, burning smell, or arcing when failing
• Works with the oven's high-voltage circuit and waveguide to deliver even cooking

• One magnetron

• High-voltage component — disconnect power and discharge the capacitor before service
• Avoid touching terminals or the ceramic insulators; handle by mounting brackets
• Verify other high-voltage components (diode, capacitor, transformer) and seals to ensure safe operation

The Diode is an OEM replacement part for LG countertop microwave models. Located internally on circuit boards regulating magnetron function, it precisely controls the electric current flow.

Causes of a bad diode involve thermal fatigue over time putting repetitive stress on sensitive semiconductor junctions. Microwave demands may accelerate failures.

Symptoms include:

• Intermittent cooking or complete failure to energize the tube
• Error codes appearing on the control panel display
• Buzzing or humming noises emitting from internal circuitry

This OEM LG part is also compatible with Sears/Kenmore microwaves.
