Jvm1840cd-002 Parts

This holder nut assembly secures a component to the appliance frame, restoring proper mounting and reducing vibration or movement. Replace a damaged or missing holder nut to keep connected parts stable and functioning. What it does:

• Secures a component or assembly to the appliance frame or mounting bracket
• Prevents looseness, rattling, and misalignment caused by worn or missing mounting hardware
• Restores a safe, stable connection that helps maintain normal operation
• Matches OEM mounting geometry for a direct replacement when the original nut is damaged

• Disconnect power to the appliance before servicing to avoid shock or injury
• Access the mounting area by removing the appropriate panel or cover per your model's service instructions
• Start threads by hand to avoid cross-threading, then tighten with the correct tool; do not overtighten
• If any fasteners or nearby components are damaged, replace them as needed for a secure installation

This microwave thermostat is a temperature-sensitive safety switch that helps protect the unit from overheating. When the preset limit is reached, it interrupts power to the affected circuit to help prevent damage and erratic shutdowns.

• Monitors temperature at its mounting location and opens the circuit if overheating is detected
• Helps protect internal components from excessive heat
• Common symptoms of a failed thermostat include: unit shuts off during cooking, won't start until it cools down, or has no power/no heat due to an open safety
• Replace if the original tests open when it should be closed

• Disconnect power by unplugging the unit or switching off the circuit breaker before servicing
• Microwaves contain a high-voltage capacitor that can retain a dangerous charge; only qualified persons should service and discharge the capacitor
• Note wire locations before removal and transfer connections firmly to the new thermostat
• Mount the thermostat securely and in the same position to ensure proper temperature sensing

This washered screw secures panels and internal components where a combined screw-and-washer fastener is required, restoring proper fit and stopping movement or rattling. Simple replacement with the correct fastener keeps assemblies aligned and stable. What it does

• Secures panels, brackets or components where a washered screw is specified
• Replaces missing, stripped or corroded fasteners that allow vibration or gaps
• Helps stop rattling, loose panels or misaligned parts caused by a failed screw
• Provides a sealed bearing surface to distribute load and prevent pull-through

• One washered screw

• Disconnect power and/or water to the appliance before starting any repair
• Use the correct screwdriver or bit to avoid cam-out and fastener damage
• Align parts before tightening and snug; avoid over-tightening which can strip threads or crack plastic

This run capacitor helps the appliance motor start and run smoothly by storing and releasing electrical energy. Replacing a worn capacitor can restore reliable motor operation and reduce abnormal motor noise or cycling. What it does:

• Provides the brief power boost motors need to start and maintain RPM
• Helps stabilize motor voltage and improve run efficiency under load
• Commonly linked to symptoms such as motors that hum but won't start, slow or intermittent motor operation, or unusual motor noise
• Reduces stress on motor windings that can lead to premature failure when functioning properly

• One motor capacitor

• Always disconnect power at the breaker or unplug the appliance before servicing
• Capacitors can hold a charge; discharge safely
• Observe proper polarity and mounting location during installation; secure wiring and connectors

This upper duct directs exhaust and airflow inside the appliance to help proper ventilation and heat management. It replaces a damaged or warped upper duct to restore correct internal airflow paths. What it does:

• Channels exhaust and internal airflow between the cooktop/vent area and the vent housing
• Restores proper airflow if the original duct is cracked, bent, or blocking ventilation
• Helps reduce unusual smells or cooking smoke reaching cabinetry by maintaining the exhaust path
• Works as a structural guide for adjacent panels and components in the vent area

• Follow the appliance service manual for disassembly steps and correct reinstallation order
• Disconnect power (and gas if applicable) before servicing to avoid shock or injury
• Use appropriate hand tools; avoid overtightening fasteners that can crack the duct or mounting tabs

This rear duct assembly channels exhaust and airflow at the back of the appliance to help maintain proper ventilation and consistent cooking performance. It replaces a damaged or rusted rear duct to restore correct air routing and safety. What it does:

• Directs exhaust and ventilation from the oven cavity to the appliance rear outlet
• Prevents hot air from escaping into adjacent components, reducing heat-related wear
• Helps maintain even temperature distribution and consistent cooking results
• Addresses symptoms like visible duct damage, rattling at the rear, or disrupted exhaust flow

• Intended for rear-panel installation; follow your appliance service manual for exact procedure
• Disconnect power and gas before beginning any repair
• Use correct fasteners and gaskets from the OEM parts list when reinstalling
