Lg Microwave JVM1790BK Parts

Holds the damper assembly in place inside the microwave cavity above the wave stirrer. Replace if bracket is bent, broken, or missing during installation.

Microwave door won't stay closed or latch? This door latch spring provides tension to secure the door shut. DIY repair in under 10 minutes with video help.

This is a micro switch that detects whether the microwave door is properly closed and latched. It is part of the safety interlock system that prevents the microwave from operating with the door open. Replace this switch if the microwave does not start when the door is shut, runs with the door open, blows a fuse when the door closes, or stops mid-cycle intermittently.

Turntable won't spin or rotates unevenly? This microwave turntable motor restores smooth rotation. Easy DIY repair—most complete it in under 10 minutes.

Color: brown. Measures about 10 inches in diameter.

The Switch, Micro is an OEM part for LG microwaves. This micro switch is crucial for the operation of the microwave door mechanism, ensuring that the microwave only operates when the door is securely closed.

Causes of a bad micro switch can include wear and tear from frequent use, damage due to electrical faults, or physical impact that disrupts its functionality.

Symptoms of a bad micro switch include:

• The microwave not starting or stopping unexpectedly
• The door not latching properly
• The microwave light not turning on or off correctly
• Error messages appearing on the control panel

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

Replace your microwave's halogen bulb to restore interior and cooktop lighting. Recommended when bulb burns out from normal use. Verify fit by model number.

Glass turntable tray for microwaves. Supports dishes and rotates for even heating. Replace if cracked, broken, or missing to restore proper rotation.

Fix F4 error codes or sensor cook failures with this microwave humidity sensor. Restores automatic cooking cycles. Moderate DIY difficulty.

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

Threaded nut assembly secures internal components in your microwave. Replace if stripped, worn, or missing to eliminate rattling and maintain alignment.

If your microwave heats unevenly or makes unusual noises, a damaged stirrer fan cover may be the cause. This cover protects the fan and ensures proper heat distribution. Easy DIY fix.

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 magnetron is the high-voltage tube that produces the microwave energy used to heat food in a countertop microwave. Replacing a failing magnetron restores normal heating performance and stops weak or no-heat conditions. What it does

• Generates microwave energy that heats food inside the oven cavity
• Stops microwave from heating when the tube fails or output is reduced
• May be the cause of loud humming, arcing, or burning smells during operation
• Works with the oven's high-voltage system and waveguide to deliver even cooking

• One magnetron

• Disconnect power before servicing and discharge the high-voltage capacitor; high-voltage components can be lethal
• Inspect and retain any mounting hardware, gaskets, and the waveguide cover for proper reassembly
• Do not operate the oven with the waveguide cover or protective shielding removed

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 holder secures the door lock assembly to the washer, keeping the latch and lock mechanism aligned for reliable door closure and operation. Replaces a worn or broken lock mounting bracket to restore proper door engagement. What it does:

• Mounts and supports the washer door lock assembly to keep the latch aligned
• Holds the lock in place so the door can fully close and lock during cycles
• Common symptoms: door won't latch, door comes loose, washer won't start, or door/lock error codes
• Prevents excessive movement that can damage the lock or striker

• Unplug the appliance and turn off water supply before beginning work
• Basic hand tools (screwdriver, nut driver) are typically required; keep fasteners for reassembly
• Handle edges and the door/lock assembly carefully to avoid damage
