This magnetron assembly produces the microwave energy used to heat food and includes a built-in thermal cutoff for overheating protection. Replacing a failed magnetron restores heating performance and safe operation in microwave ovens. What it does:

• Generates high-frequency microwaves that cook and warm food.
• Thermal cutoff helps stop operation if the magnetron overheats.
• Commonly replaced when the oven stops heating, heats intermittently, or has weak heating.
• If the oven produces loud humming, arcing, or unusual burning smells.

• Disconnect power and unplug the appliance before service.
• High-voltage components (magnetron and capacitor) can retain lethal charge — discharge the capacitor and follow safety procedures.
• Handle the magnetron carefully; avoid touching terminals or the ceramic output window.

This fan motor spins the oven/convection fan to circulate heat for even cooking and help exhaust hot air. Replaces a worn or noisy motor to restore proper airflow and temperature consistency in the appliance. What it does:

• Drives the convection/circulation fan blade to move air through the oven cavity
• Helps maintain even cooking and consistent oven temperatures
• Reduces buzzing, grinding, or failure-to-spin symptoms when the old motor is failing
• Works as the mechanical drive for air exhaust and internal circulation systems

• Disconnect power to the appliance before servicing to avoid electrical shock
• Handle the motor and wiring gently; match mounting orientation and connector type during install
• Verify blade and shroud clearance before powering the unit

This high-voltage transformer supplies the ignition voltage used to create sparks for gas burner/oven ignition. Replaces a worn or failed transformer to restore reliable spark firing and consistent burner ignition. What it does:

• Converts line voltage to the high-voltage pulse needed for spark ignition
• Sends ignition sparks to surface burners or oven igniters so gas will light
• Common symptom: clicking with no visible spark at the burner or burner(s) that fail to ignite
• Other symptom: intermittent ignition or weak sparking

• One high-voltage transformer

• Disconnect power to the appliance before servicing to avoid electrical shock
• Handle the transformer and high-voltage leads with care; do not operate with covers removed
• Verify correct diagnosis before replacing; check ignition module, wiring, and spark electrodes for faults

This small spacer positions and stabilizes the oven rack inside the cavity. Replacing a worn or missing spacer restores correct rack height and alignment so the rack slides smoothly without scraping or wobbling during use.

• Maintains proper clearance between the rack and oven wall/rail
• Keeps the rack level and correctly aligned on its supports
• Helps the rack slide in and out smoothly
• Direct replacement for a cracked, deformed, or missing spacer

• Disconnect power; if gas, shut off gas supply. Allow the oven to cool completely.
• Remove the rack and note the spacer's original location and orientation.
• Install the spacer in the designated position and ensure it is fully seated.
• Reinstall the rack and ensure smooth movement and secure support.

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 noise filter assembly reduces electrical interference on the appliance's power line to help prevent control malfunctions and limit radio/TV interference. It replaces a damaged or noisy filter to restore proper, quieter operation. What it does:

• Filters EMI/RFI on the incoming power line to reduce electrical noise
• Helps prevent interference-related control/display glitches and resets
• Can stop buzzing or intermittent electrical noise caused by a failing filter
• Protects downstream control boards and sensitive electronics from transient noise

• Disconnect power at the breaker or unplug the appliance before servicing.
• Observe original wiring orientation and secure all connectors; replace only with identical part.
• Use basic hand tools; avoid shorting terminals or touching energized circuits.

This magnetron is the high-voltage tube that generates the microwave energy used to heat food in compatible microwave ovens. Installing a new magnetron restores microwave heating when the tube has failed. What it does:

• Converts high-voltage electrical energy into microwave radiation to heat food
• Restores heating when oven powers up but does not heat or has weak heating
• Addresses humming, arcing/ sparks, or blown microwave fuses caused by a failed tube
• Works as the core microwave source; must be used with intact waveguide and protective cover

• One magnetron (quantity: 1)

• High-voltage components retain lethal charge; disconnect power and discharge the capacitor before service
• Inspect and replace any damaged waveguide cover or high-voltage wiring when installing
• Do not operate the microwave with the outer cover removed; follow OEM torque and mounting instructions

This wire oven rack provides a stable, heat-resistant surface for cookware and bakeware, restoring proper support and cooking alignment in your oven. Designed to slide into existing shelf tracks for everyday use. What it does

• Supports pots, pans and bakeware for even cooking and roasting
• Restores proper shelf height and prevents cookware from tipping
• Allows smooth sliding in and out of the oven on existing track guides
• Replaces bent, warped or missing oven shelving that interferes with cooking

• One wire oven rack

• Slide the rack into the oven's shelf guides until fully seated; no tools typically required
• Allow the oven to cool before handling and wear gloves to avoid sharp edges
• Verify correct orientation (flat side up) and that rack locks into track stops
• Check for bent guides or obstructions before forcing
