Lg Microwave JVM1790BK Parts

This is a replacement screw used to secure appliance components and panels. It restores proper fastening where a stripped, missing, or damaged screw causes loose parts or rattling. What it does:

• Fastens panels, trim, or internal components to maintain structural fit
• Helps stop vibration-related noise from loose assemblies
• Replaces missing or corroded screws that prevent proper closures
• Restores secure mounting after repairs or disassembly

• Use the correct screwdriver or bit to avoid stripping the head
• Tighten until snug—do not over-torque to prevent thread damage
• Keep small parts away from children and pets
• Disconnect power or water before accessing internal parts

Fix weak or noisy ventilation with this microwave blower fan. Restores proper airflow when exhaust isn't working. Moderate DIY repair in 30-45 minutes.

Fix a microwave that overheats or shuts off unexpectedly with this cooling fan motor. Direct replacement part restores proper ventilation and cooling.

Microwave turntable not rotating? This synchronous AC motor drives the turntable rotation. Common DIY repair, typically takes 15-30 minutes.

The Time Delay Fuse is an OEM part for LG microwaves. This fuse provides a safety mechanism by delaying the flow of electricity, protecting the microwave's electrical components from power surges and ensuring the appliance operates safely. It helps to prevent immediate damage in the event of a power surge or electrical fault, thus prolonging the lifespan of the microwave.

Over time, the time delay fuse can become damaged due to electrical surges, wear and tear, or faulty connections. If the fuse blows, it can disrupt the microwave’s ability to function correctly.

Symptoms of a bad time delay fuse include:

• The microwave not turning on
• No response from the microwave control panel
• The microwave stopping unexpectedly during operation
• Electrical issues or blown circuits in the microwave

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

The Common Nut is an OEM part for LG ranges. It secures the fan blade to the motor shaft. This nut maintains the fan's stability and preventing it from becoming dislodged during use.

Causes of a bad common nut can include loosening over time due to vibration, improper installation, or damage from impact or mishandling.

Symptoms of a bad common nut include:

• Excessive noise or vibration from the fan assembly
• The fan blade becoming loose or detached, causing poor air circulation
• Potential risk of the fan blade becoming a projectile if completely detached

This OEM LG part is also compatible with some Kenmore models.a

This is a motor start/run capacitor that helps the appliance's motor start and run smoothly by supplying a brief boost of electrical energy. Replacing a failing capacitor restores reliable motor startup and operation. What it does:

• Provides the brief electrical surge needed to start and keep the motor running
• Commonly linked to motors that hum, fail to start, or run intermittently
• Helps prevent overheating from repeated start attempts when functioning properly
• Works with the appliance's start circuitry to ensure consistent performance

• Disconnect power to the appliance before accessing electrical components
• Discharge the capacitor and use insulated tools
• Observe polarity/terminal layout and secure connections to factory specifications
• Dispose of the old capacitor according to local electronic-waste regulations

Replaces cracked, broken, or warped outer door frame on your microwave. Secures door glass and maintains proper alignment. Restores appearance.

Drive shaft that connects the motor to the turntable system in your microwave. Replace when the original shaft is worn, stripped, or damaged.

A flat washer used with the appliance's fastening hardware to distribute load and reduce wear. Helps maintain secure connections and prevents damage to mating surfaces for reliable operation. What it does:

• Provides an even bearing surface for bolts or screws to prevent pull-through
• Reduces friction and wear between fasteners and housing parts
• Helps keep fasteners tight and resists loosening from vibration
• Commonly used where a smooth, protective spacer is needed

• Verify correct location and orientation before reassembly
• Use manufacturer-recommended fasteners and torque specifications
• Power off and unplug the appliance before accessing internal components

Microwave won't heat or makes humming noise? High voltage capacitor stores energy for the magnetron. Moderate DIY repair, requires safe discharge.
