Jvm1790 Parts

Replace your cracked glass tray or broken roller ring to restore smooth, stable rotation. Fits inside microwave cavity to support dishes during cooking.

Complete mounting hardware kit for installing over-the-range microwaves. Includes brackets and fasteners to secure unit above cooktop. Replace missing or damaged parts.

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

Mounting hardware kit for over-the-range microwaves. Includes screws, nuts, and washers to secure microwave during installation. Replace missing hardware.

Fix a microwave vent fan that won't remove smoke or steam with this ventilation motor. Restores proper airflow to clear cooking odors effectively.

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

Truss head tapping screw secures panels, brackets, and covers in appliances. Replaces missing or damaged fasteners to restore snug fit and alignment.

This is a small synchronous motor used in microwave ovens to drive components such as the turntable or air damper. It operates at a steady rotational speed to ensure consistent movement during cooking. Replace this motor if the turntable stops spinning, rotates intermittently, or if you hear a humming noise without any movement.

This humidity sensor detects moisture levels inside the microwave cavity during cooking, allowing the control board to automatically adjust cook time and power. It is typically mounted inside the cooking compartment or vent area. Replace this sensor if your microwave's auto-cook or sensor-cook modes no longer work correctly, food is consistently overcooked or undercooked, or the unit displays a sensor error code.

Fixes weak ventilation, excessive noise, or overheating in your microwave. This blower wheel restores proper airflow to clear steam and cool components.

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.

Secures microwave components to their mounting points. Replace this nut assembly if damaged, missing, or worn to prevent rattling and keep parts aligned.

This AC fan motor drives the cooling fan inside a microwave or combination cooking unit, circulating air to prevent internal components from overheating during operation. It helps protect the magnetron, control board, and other electronics by dissipating heat. If your microwave overheats frequently, shuts off mid-cycle, or you no longer hear the cooling fan running, this motor likely needs replacement.

Suction guide bracket that positions and supports the suction component inside your microwave. Replace if cracked, broken, or missing to restore proper alignment.
