Jvm1640bb-002 Parts

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 evaporator fan motor assembly circulates cold air through the refrigerator compartment to help maintain even cooling and proper temperature control. Replacing a failed fan restores airflow and helps the appliance cool correctly. What it does:

• Moves air across the evaporator coil so the refrigerator/freezer can cool efficiently
• Commonly replaced when there is little or no airflow from the fresh-food or freezer section
• Can stop excessive frost build-up on the evaporator caused by poor circulation
• May reduce unusual noise if the original motor bearings have failed
• Helps prevent uneven temperatures that can cause food spoilage

• One evaporator fan motor assembly as shown

• Disconnect power to the appliance before starting any repair
• Access may require removing interior panels or the evaporator cover
• Handle the fan blades carefully to avoid bending or cracking; ensure proper blade seating on the motor shaft

This magnetron generates the microwave energy that heats and cooks food in a microwave oven. Replacing a failed magnetron restores heating performance so your microwave can again cook and reheat reliably. What it does

• Converts high-voltage electrical energy into microwave radiation used to heat food
• Common symptom: microwave runs but does not heat or heats weakly
• A failed magnetron can trip fuses or circuit breakers inside the oven

• Disconnect power and verify the appliance is unplugged before service
• High-voltage components (magnetron, capacitor, transformer) can hold lethal charge — discharge the capacitor and follow safety procedures
• Use proper replacement hardware and gasketing as required; secure mounting and shielding per OEM instructions

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 gas flame sensor detects whether a burner's flame is present so the range/oven's gas valve and ignition control can operate safely. It helps restore reliable ignition and prevents the valve from staying open when no flame is detected. What it does:

• Senses the presence of a gas flame and signals the control to keep the valve open
• Helps prevent gas flow if a flame is not detected
• Can stop ignition or cause the oven/range not to heat when failing
• Commonly replaced when burners won't stay lit or control shows ignition-related errors

• One gas flame sensor

• Turn off electrical power and shut off the gas supply before servicing
• Handle the sensor and its connector carefully to avoid damage
• Reinstall in the exact position and orientation; loose connections can cause false faults

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 stirrer assembly circulates microwave energy inside the cavity so food heats more evenly and prevents cold spots. It replaces a damaged or noisy stirrer that can cause uneven cooking or unusual microwave noise. What it does:

• Spins the microwave stirrer to help distribute microwave energy for more even heating
• Reduces hotspots and cold spots during cooking
• Stops or reduces rattling, grinding, or squealing noises when the original stirrer is worn
• Helps prevent arcing or sparking caused by a cracked or broken stirrer cover

• Disconnect power at the breaker or unplug the appliance before servicing to avoid electrical shock.
• Access may require removing the microwave's outer cabinet or control panel; follow OEM service manual steps.
• Handle the stirrer and cover carefully—plastic parts can crack if forced.

This mounting bracket secures the H.V.C. assembly or cover in place to keep high-voltage components stable and properly aligned. Replacing a damaged or bent bracket restores correct support and reduces movement-related issues. What it does:

• Secures the high-voltage cover/assembly to the appliance chassis to prevent shifting.
• Maintains correct clearance and alignment for high-voltage components.
• Helps reduce noise or arcing caused by a loose cover or bracket.
• Supports safe, reliable operation by keeping wiring and insulating parts in position.

• Disconnect power at the breaker or unplug the appliance before starting work.
• Handle high-voltage components and insulating parts carefully; avoid contact with charged parts.
• Use the OEM part number to fit and orientation before installation.
