Parts for Lg LMVH1750ST / AS1ELGA: Section 5 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

A small replacement fastening nut used to secure components on LG appliances. Replacing a worn or missing nut restores a secure fit and helps eliminate looseness or rattling for reliable operation. What it does

Color: brown. Measures about 10 inches in diameter.

This drive shaft transfers motor torque to the appliance drum or tub, restoring proper rotation and reducing wobble. A direct-fit replacement designed to return smooth, quiet operation when the original shaft is worn or damaged. What it does

• Connects the motor/transmission to the drum or tub so the drum can spin.
• Restores correct alignment and rotation to reduce wobbling or scraping.
• Helps stop symptoms like noisy operation, grinding, or a drum that won't turn.
• Works as the mechanical link in drive assemblies where a worn shaft prevents normal function.

• Disconnect power and water supply, and drain the appliance before beginning service.
• Access may require removing the cabinet, front panel, or tub—follow the service manual for your model.
• Use appropriate tools and follow OEM instructions for safe removal and reassembly.

A high-voltage capacitor for the appliance's high-voltage circuit that stores and releases electrical energy to support proper heating operation. Replacing a failing capacitor can restore consistent heating and prevent related electrical faults. What it does:

• Stores and delivers high-voltage energy used by the magnetron/ high-voltage assembly to generate heat.
• Failure may cause no-heat or weak-heat conditions in the oven.
• Faulty capacitors can contribute to arcing, loud humming, or blown high-voltage fuses.
• Works as part of the HV circuit; not a user-serviceable low-voltage control.

• High-voltage components can hold a dangerous charge—disconnect power and discharge the capacitor before servicing.
• Use insulated tools and avoid touching terminals; verify proper operation with appropriate test equipment.

The drawing capacitor is an OEM component for LG countertop microwaves. It is an integrated electric part that stores and releases power allowing the main control board to communicate smoothly with high-load cooking components like the magnetron tube and turntable motor.

Symptoms of a bad drawing capacitor include: 

• Microwave failing to power on or start cooking presets  
• Components like the turntable or magnetron not engaging
• Unusual crackling or burning smells from internal circuits
• Control panel displaying error codes for capacitive malfunctions

Causes can be normal component fatigue or manufacturing defects after extended use.

This OEM LG part can also be used on Kenmore/Sears appliances. 

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.

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

• Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
• Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
• Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
• Use when the existing sensor fails to report correct temperatures or the part number matches.

• Always disconnect power to the appliance before servicing to avoid shock or damage.
• The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
• Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

This thermostat is a temperature-sensitive safety switch used in LG microwaves. It monitors internal temperature and opens the circuit when overheating is detected to help protect components from heat damage.

• Monitors temperature at its mounting location inside the microwave
• Opens on overtemperature to interrupt power for safety
• Depending on model/location, a failed or open thermostat can cause no heat, the unit shutting off mid-cycle, or no power until it cools
• Helps prevent damage to the magnetron, cavity, and wiring due to overheating

• Unplug the microwave before service; the high-voltage capacitor can retain a dangerous charge
• Note wire positions, remove mounting screws, and install the new thermostat flat against the surface for proper heat sensing
• Reassemble and test; ensure vents and filters are clear to maintain proper airflow and prevent future overheating

A molded air guide that channels internal airflow to improve circulation and component cooling inside the appliance. Replaces a worn or broken guide to restore designed airflow paths and reduce air leaks. What it does

• Directs and channels airflow through the appliance to support proper ventilation and cooling.
• Helps maintain consistent operating temperatures by guiding air where the manufacturer intended.
• Common symptom: reduced airflow or cooling performance, longer cycle times, or inconsistent operation.
• Common symptom: rattling or vibration if the guide is cracked, loose, or damaged.

• One air guide.

• Disconnect power (and gas, if applicable) before beginning any repair.
• Inspect mounting tabs and surrounding seals; replace any damaged fasteners to ensure a secure fit.
• Handle the plastic guide carefully to avoid cracking; align tabs and press into place until seated.
• Test operation after installation; recheck for unusual noises or airflow issues.

The Turntable Motor is an OEM replacement part for LG microwaves. Located under the microwave cavity, it rotates the special turntable platter during cooking operations.   

Symptoms of a faulty turntable motor include:

• Turntable failing to spin or rotating unevenly during cooking  
• Abnormal noises or vibrations coming from the bottom of the unit
• Uneven cooking results along microwave perimeter 

Causes related to normal wear of internal motor workings through extended use. Damage from power surges is also possible over time.

This LG replacement part is compatible with some Kenmore models as well.
