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 turntable coupler connects the microwave's motor shaft to the glass tray so it rotates smoothly for even heating. Replace a worn or cracked coupler to restore reliable tray rotation and consistent cooking performance.

• Couples the turntable motor shaft to the glass tray to drive rotation
• Helps keep the tray centered and moving smoothly
• Common symptoms: tray not turning or stopping intermittently
• May cause uneven heating and clicking or grinding noises from the turntable area

• Disconnect power to the microwave before servicing
• Remove the glass tray and roller ring; lift the old coupler straight up from the motor shaft
• Align the new coupler with the shaft flat/splines and press down until fully seated; reinstall roller ring and tray

Replacement thermostat that senses and controls the appliance heating system to restore accurate heating and stable temperature cycles, helping the appliance reach and maintain the set temperature. What it does:

• Senses temperature and signals the heating element or valve to turn on/off to maintain set temperature.
• Commonly linked to symptoms such as failure to reach set temperature, temperature fluctuating or cycling erratically, or continuous heating.
• Works as the temperature-regulation component in the appliance's control pathway to stabilize performance.
• Matches the OEM function for temperature control; use when thermostat diagnostics indicate a failed or inaccurate sensor.

• Disconnect power to the appliance before attempting removal or installation to avoid shock or ignition hazards.
• Handle the sensing element and terminals carefully to avoid damage; ensure secure electrical connections and proper routing of any capillary or sensor lead.
• After installation, test the appliance through a full heat cycle to confirm correct operation.

This glass turntable provides a stable, heat-resistant surface for even cooking and serving in compatible countertop and over-the-range microwaves. Replaces a cracked, chipped, or missing tray to restore proper food rotation and support. What it does:

• Serves as the primary cooking surface that rotates food for more even heating.
• Supports cookware and plates while preventing direct contact with the microwave floor.
• Restores proper rotation when the original tray is broken, chipped, or missing.
• Helps keep the interior cleaner by containing spills and splatters on an easily removed surface.

• Unplug the appliance or disconnect power before removing or installing the tray.
• Handle carefully—use gloves if the old tray is cracked or shattered to avoid cuts.
• Set the tray onto the roller guide/drive hub so it seats flat and rotates freely; verify smooth rotation before use.
• If rotation is still impaired after installing the tray, inspect the roller ring and drive coupling for damage and replace as needed.

This replacement tray restores a damaged or worn internal tray to help contain spills and stabilize components for reliable appliance operation. It provides a like-for-like fit where the original tray is cracked, warped or missing. What it does:

• Holds and contains water, ice melt, or minor spills to protect interior cabinet surfaces
• Supports nearby components and helps maintain proper alignment
• Prevents leaks from spreading and reduces risk of odors or corrosion
• Replaces trays that are cracked, warped, broken or otherwise damaged

• One replacement tray

• Turn off power to the appliance before attempting service
• Remove nearby shelving or panels to access and remove the old tray; use gentle prying if needed
• Inspect surrounding seals and components and replace any damaged parts to prevent future leaks

A rotating ring assembly that supports the oven/microwave glass turntable and helps it rotate smoothly for even cooking. Replaces a worn or damaged support ring to restore stable, quiet tray rotation. What it does:

• Supports the glass turntable and keeps it centered while rotating
• Provides low-friction rolling action so the tray turns smoothly
• Reduces wobble, scraping or grinding noises during rotation
• Helps ensure even cooking by maintaining steady tray movement

• Disconnect power (unplug or shut off breaker) before servicing
• Remove the glass tray and old support ring, then position the new ring in the cavity so rollers align with the turntable
• Re-seat the glass tray and test rotation by hand before restoring power
• Handle the glass tray carefully to avoid chipping or injury

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 rivet assembly is a direct-replacement fastening piece used to secure appliance panels and components, restoring a stable, rattle-free fit and preventing movement caused by worn or broken rivets. What it does:

• Secures panels, brackets, or component mounts to restore proper alignment and support
• Stops rattling, vibration, or loose hardware caused by damaged or missing rivets
• Provides a durable mechanical fastener where original rivets have sheared or loosened
• Helps maintain safe operation by keeping parts properly retained

• Disconnect power (and gas/water if applicable) before attempting any repairs
• Removal may require drilling out the old rivet; installation typically needs a rivet gun or equivalent tool
• Keep hardware orientation the same as the original; replace any damaged surrounding parts

A small replacement push-button spring that restores reliable button return and control feel on affected appliances. Replaces worn or broken button springs so controls snap back and operate more consistently. What it does:

• Provides tension behind a push button so the button returns to its original position after pressing
• Restores proper button feel and prevents buttons from sticking or remaining depressed
• Helps resolve intermittent or unresponsive control-button action caused by a weak or broken spring
• Used in push-button/control-panel assemblies where a compact compression spring is required

• Disconnect power to the appliance before accessing controls to reduce shock risk
• Remove the control panel or button assembly per your model's service instructions; keep small parts secure
• Note spring orientation and seating; use needle-nose pliers if needed to position the spring carefully

This door lever is the user-access handle component that lets the appliance door open and latch reliably. It replaces a damaged or broken lever to restore normal door operation and safe access. What it does:

• Provides the handle/lever action needed to open and close the appliance door
• Restores a secure latch action when the original lever is cracked, worn, or broken
• Stops sticking or slipping that can prevent the door from opening smoothly
• Helps prevent further damage to the door assembly by replacing a compromised lever

• Disconnect power to the appliance before beginning any work to avoid shock or injury
• Basic hand tools typically required; access may require removing the door or inner panel
• Inspect surrounding trim and mounting points for damage; replace additional parts if worn
