This magnetron capacitor is the microwave high-voltage capacitor that helps supply the magnetron with the pulse of energy needed to produce heat. Replacing a failing capacitor restores normal heating performance and reduces arcing or loud humming. What it does

• Stores and releases the high-voltage pulse required by the magnetron so the microwave can generate heat.
• Prevents unstable magnetron operation that can cause weak or no heating.
• Common symptoms of a failing capacitor: oven runs but doesn't heat, intermittent heating, loud buzzing/humming, or visible arcing inside the cavity.
• A failed capacitor can also cause blown internal fuses or tripped circuits.

• One capacitor.

• Disconnect power and verify the appliance is completely de-energized before servicing.
• Capacitors can hold dangerous charge; discharge the capacitor safely with an insulated tool.
• Use the exact replacement part and follow the appliance service manual for routing and connections.

This mounting plate anchors the back of an over-the-range microwave to the wall studs, providing the primary support for installation. Replace a bent, damaged, or missing plate to restore a safe, level, and secure mount.

• Provides the rear-wall anchor point the microwave hangs on during installation
• Helps keep the unit level and securely supported under normal use
• Enables proper alignment so top mounting hardware can fasten correctly
• Typical symptoms: can't hang or align the microwave, unit sags/tilts, rear hooks won't engage, plate is bent or corroded

• Disconnect power before beginning
• Use two people to remove/hang the microwave for safety
• Locate wall studs, level the plate, and fasten per your model's installation instructions with the correct hardware
• The microwave's rear tabs fully engage the plate before final tightening

This magnetron is the microwave's high-voltage tube that generates the microwaves responsible for heating food. Use it as a direct replacement when your microwave powers on but no longer heats properly. What it does:

• Generates the microwave energy that heats and cooks food inside the oven cavity.
• A failing magnetron commonly causes the oven to run but not heat; other signs can include weak or uneven heating.
• Can produce unusual humming, arcing or sparking inside the cavity, or a burning smell when failing.
• Works as part of the high-voltage circuit; other components affect overall function.

• Disconnect power and unplug the appliance before servicing; the high-voltage capacitor must be safely discharged.
• Handle the magnetron carefully by the mounting flange—avoid touching the ceramic antenna or terminals.
• Verify exact part number compatibility with your model before ordering; some repairs require replacing other high-voltage components.

This lamp holder, also called a light socket, secures the bulb and provides the electrical connection so the appliance light works reliably. Replace a heat-damaged or loose socket to restore steady illumination.

• Holds the bulb in place and provides electrical contacts
• Helps fix a light that won't turn on, flickers, or works intermittently
• Addresses signs of heat damage, arcing, or a burnt/melted socket
• Ensures proper bulb seating for consistent lighting

• Disconnect power at the breaker or unplug the appliance before servicing
• Allow the area to cool and handle glass bulbs with care
• Transfer wires to the new holder one at a time to maintain correct connections
• Microwaves contain high-voltage components; avoid internal access unless properly trained

This lamp cover is the replacement lens that protects and diffuses your oven's interior light, restoring even illumination while keeping the bulb shielded from heat and food residue. It helps maintain safe, usable oven lighting. What it does:

• Protects the oven light bulb from splashes, crumbs and direct contact.
• Diffuses the bulb for more even interior illumination.
• Replaces a cracked, cloudy, melted or missing lens that can cause dim or exposed lighting.
• Fits over the lamp housing to restore the oven's normal light appearance and function.

• Disconnect power to the appliance before starting and allow the oven to cool completely.
• Handle the cover carefully—wear gloves to protect from sharp edges or broken glass.
• Remove any retaining screws or clips, swap the old cover for the new one, then secure the retainer.
• After installation, restore power and replace the bulb if issues persist.

This fixed-temperature thermostat is a temperature-sensing safety switch that opens at a set limit to help prevent overheating and protect heating systems. Use it to restore proper thermal cutoff control in affected appliances. What it does:

• Senses internal temperature and opens the circuit when a set limit is reached to stop heating
• Acts as a high-limit/thermal cutoff to prevent overheating and potential damage
• Can restore normal heating control when a faulty limiter causes shutdowns or safety trips
• Common symptom link: appliance heater runs erratically, will not heat, or heats continuously and may trip safety circuits

• One fixed-temperature thermostat

• Disconnect power to the appliance before inspecting or replacing the thermostat
• Handle and test with care; verify continuity with a multimeter to confirm failure before replacing
• Follow the appliance service manual and wiring diagrams for correct location and wiring

This capacitor stores and releases electrical energy to help an AC motor start and run smoothly. Replacing a weak or failed capacitor can restore reliable motor operation and reduce humming, no-start, or stall conditions.

• Provides the phase shift and starting torque an induction motor needs to start
• Helps the motor reach and maintain proper speed under load
• Common symptoms of a failing capacitor: motor hums but won't start, intermittent starts, slow or stalled rotation, or frequent thermal trips
• Visible clues may include a swollen case or leaking residue

• Disconnect power to the appliance before servicing; verify no voltage is present
• Capacitors can retain a charge—discharge safely before handling
• Note wire positions; move leads to the new capacitor one at a time and ensure snug terminal fit
• Reuse the original bracket/clip if applicable and secure the capacitor to prevent vibration

This piston assembly restores the moving piston used in the appliance's fluid/valve system to help recover proper dispensing and motion. It replaces a worn or damaged piston so the affected function can operate as intended. What it does:

• Replaces the piston that moves inside a valve or dispenser to control fluid or airflow
• Restores proper actuation and sealing that can prevent drips or improper dispensing
• Commonly installed when symptoms include poor dispensing, leaks near the valve area, sticking motion, or unusual noises during operation
• Works as a direct-fit replacement where this OEM piston assembly is specified

• One piston assembly as shown

• Disconnect power (and water supply or gas, if applicable) before starting any repair
• Follow the appliance service manual and use appropriate tools; keep small fasteners and seals organized
• Inspect sealing surfaces and O-rings; replace damaged seals to ensure a leak-free install
• Test the appliance after installation to confirm correct operation

This molded wire support clip secures wiring and small harnesses to the appliance cabinet or components to prevent rubbing, pinching, or contact with moving/heat-producing parts. It helps reduce chafing and electrical wear for safer, more reliable operation. What it does:

• Holds wiring harnesses and individual wires in place to prevent contact with sharp edges, motors, or heating elements
• Minimizes wire movement and vibration that can lead to chafing or broken conductors
• Helps maintain proper routing for consistent connections and component performance
• Commonly used where a small push-fit retainer is needed to secure low-voltage or signal wires

• One wire support clip as shown

• Disconnect power to the appliance before servicing to avoid shock or injury
• Push-fit installation: align clip over wire/harness and press into the mating hole or slot until it snaps in place; clip may require slight flexing
• Inspect surrounding wiring and routing for damage; replace any frayed or exposed wires before reassembly
• If the mounting hole or panel is damaged, use the correct replacement panel or a suitable repair to ensure a secure fit
