Mmv520bws-1 Parts

This block-style fuse holder secures and connects the appliance fuse to the wiring harness, restoring a safe electrical connection and thermal protection. Use it when the original fuse block is cracked, corroded, or no longer holding the fuse securely. What it does:

• Holds and connects the appliance fuse to the wiring harness so the thermal/overload fuse can function.
• Restores reliable electrical contact when the original block is cracked, melted, or corroded.
• Addresses symptoms such as intermittent power, no heat, or appliance not starting when caused by a bad fuse connection.
• Works with the existing fuse and wiring—does not replace the fuse itself.

• Disconnect power to the appliance before inspecting or replacing this part.
• Replace any damaged wiring, connectors, or insulation found during replacement; do not cut corners or bypass thermal safety devices.

Color: White

Sheet metal pan head screw secures panels, brackets, and components to appliance cabinets. Replace missing, stripped, or corroded screws to restore fit.

Microwave runs but won't heat food? A failed magnetron is the most common cause. This RF energy tube replacement restores heating in 30-60 minutes.

Replace your cracked or broken microwave door handle. Installs on the exterior door panel. Includes mounting hardware for secure attachment.

Microwave not heating or sparking inside? This high voltage capacitor stores power for the magnetron. Common repair taking 30-45 minutes with care.

Halogen bulb restores bright interior lighting so you can monitor cooking without opening the door. Replace when dim or burnt out. Verify fit by model.

Replacement lamp cover lens for microwave ovens. Protects and diffuses interior light. Replace if cracked, discolored, or missing to restore lighting.

Protective inlet cover for microwaves. Shields wiring and connections from debris. Replace if cracked, broken, or missing to restore safe coverage.

This thermostat controls oven/dryer temperature by opening or closing its contacts as the appliance reaches set temperatures, helping maintain safe and consistent operation. Replaces a worn or failed thermostat to restore proper temperature regulation. What it does:

• Senses temperature and interrupts heating when limits are reached to prevent overheating
• Re-establishes heating when temperature falls, maintaining normal cycle performance
• Commonly installed when an appliance won't heat, overheats, or cycles erratically
• Works as a direct replacement for the OEM thermostat designed for compatible LG units

• One thermostat

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Note wire locations or take a photo before removing wiring; reconnect wires to the same terminals
• Use a multimeter to verify thermostat continuity and correct operation before and after replacement

This plastic actuator engages the door interlock switches when the microwave door is closed, ensuring the appliance only operates when the door is fully latched. It translates the motion of the door latch into the switch activation needed for safe operation. Replace this part if the microwave won't start, runs with the door open, or the door doesn't latch securely.

Microwave not heating but all other functions work? This magnetron thermostat protects against overheating. Easy DIY repair in under an hour.

Molded wire clip that secures wiring and harnesses to the microwave cabinet. Replace if broken, cracked, or missing to prevent wire rubbing and chafing.

This is an electronic filter board that suppresses electrical noise generated by the microwave, preventing interference with other household electronics. It is typically mounted near the power cord connection inside the microwave's cabinet. Replace this part if the microwave causes static on nearby radios or TVs, trips breakers, or fails to power on at all.

If your microwave runs but won't heat, a failed magnetron capacitor may be the cause. This high-voltage component stores energy for the magnetron.
