Kenmore Range 790.78402012 (79078402012, 790 78402012) Parts

This control mounting hex nut secures the burner or oven control to the control panel, keeping the shaft stable so the knob turns smoothly and the switch stays properly aligned.

• Threads onto the control/infinite switch or thermostat bushing to fasten it to the panel
• Prevents the control from rotating or shifting when the knob is turned
• Replace if the original nut is missing, stripped, rounded, or corroded
• Common signs: loose or wobbly knob, switch spins in the panel, or misaligned knob indexing

• Disconnect power; for gas appliances, also shut off gas before servicing
• Pull off the knob and any trim; support the control body from behind the panel while removing/installing the nut
• Start the new nut by hand to avoid cross-threading; tighten snugly with the correct-size wrench—do not overtighten
• The control sits square in the panel and the knob operates smoothly before restoring power

This manifold supply tube routes gas from the appliance's inlet/regulator to the burner manifold and valves. Replacing a damaged tube helps restore safe, consistent fuel delivery and reliable burner performance. What it does

• Channels gas from the regulator/inlet to the burner manifold/valve assembly
• Maintains proper fuel flow to multiple burners
• Replace if the tube is bent, cracked, corroded, or leaking
• Symptoms can include multiple burners not lighting or weak/uneven flames due to restricted flow

• 1 manifold supply tube

• Shut off the gas supply and disconnect electrical power before servicing
• Note the routing and orientation of the original tube to match bends and connections
• Use only approved practices for your fitting type; do not apply sealant to flare-seat connections
• After installation, perform a soap-and-water leak test on all joints; do not operate if bubbles appear

This oven rack is a replacement wire shelf that supports cookware and bakeware inside the oven cavity, restoring proper spacing and airflow for even cooking and broiling. Ideal when the original rack is bent, rusted, or missing. What it does:

• Provides a stable surface for pans, baking sheets and cookware
• Restores correct oven spacing for even heat circulation
• Replaces bent, warped or corroded racks that catch or bind
• Enables use of multiple rack positions for different cooking needs

• Allow the oven to cool completely and disconnect power before installing
• Position rack with the rolled edges toward the oven walls and slide into desired rack guides
• Use gloves to avoid sharp edges and protect finishes
• Clean gently with non-abrasive cleaners; do not use oven self-clean while rack is in place unless rack is rated for self-clean cycles

This cabinet insulation helps reduce heat transfer inside the refrigerator, supporting stable temperatures and efficient cooling. Replacing damaged or missing insulation can improve temperature control and reduce frost buildup. What it does:

• Fills gaps between the cabinet and liner to slow heat transfer and maintain internal cold
• Helps the appliance reach and hold set temperatures more consistently
• Reduces condensation and excess frost on interior surfaces
• Can improve compressor run-time and overall energy efficiency when intact

• Disconnect power before starting
• Remove food and shelving from the compartment before accessing the insulation
• Handle insulation carefully to avoid tearing; secure per manufacturer routing and adhesive points
• Dispose of old insulation per local regulations

This orifice is the small gas jet that meters fuel to a range or oven burner, helping restore correct flame size and consistent heat for reliable cooking performance. What it does:

• Controls the gas flow to a burner, producing the correct flame for even heating
• Commonly used when flame is unusually small, weak, or uneven
• Helps address burners that light slowly or do not reach proper temperature
• Works as part of the burner assembly with the regulator and valve to maintain safe operation

• One orifice

• Turn off gas supply and electrical power before starting work
• Do not force threads; use appropriate thread sealant if specified by OEM
• After installation, check all fittings for leaks with a gas-safe detector or soapy water

This genuine oven bake element heats the oven cavity for baking and roasting, restoring proper cooking temperatures and consistent results. Replaces a damaged or non-heating bake element to bring your oven back to service. What it does:

• Heats the oven cavity so food reaches and holds set temperatures
• Restores even baking and roasting when the oven fails to heat
• Replaces elements that show visible damage, burn-through, or no glow
• Works with electric ovens that use a separate bake heating element

• Disconnect power to the appliance at the breaker before starting work
• Handle the element carefully to avoid bending or damaging terminals
• Remove oven racks and access the element from inside the oven
• Verify proper fit and secure mounting; tighten terminal fasteners firmly and restore power to test

This inner oven door glass replaces a cracked, broken or fogged inner door panel to restore thermal performance and visibility into the oven cavity. It helps keep heat in the oven and prevents direct exposure to the internal cavity. What it does:

• Replaces damaged or cracked inner oven door glass that can compromise heating and safety
• Restores the oven door's insulating layer to reduce heat loss and improve cooking consistency
• Provides a clear viewing window to check food without opening the door
• Stops rattling or vibration caused by loose or broken glass

• Disconnect power to the appliance and ensure the oven is completely cool before starting
• Wear cut-resistant gloves and eye protection when handling glass to avoid injury
• Some installations require removing the oven door and disassembling door screws or clips; keep fasteners organized

This trim piece finishes the appliance door opening and restores a clean, finished appearance. It covers the edge of the door/frame to improve looks and help prevent gaps where dirt could collect. What it does

• Replaces cracked, chipped, or missing decorative trim along the door or frame
• Restores a smooth, finished edge and consistent appearance after damage or disassembly
• Helps reduce dust and debris buildup in the gap between the door and cabinet
• Prevents sharp or jagged edges where the original trim is broken

• One replacement trim piece as shown

• High-level, no-specialty tool install; typically snaps or screws into place—keep original fasteners when possible
• Power off and unplug the appliance and ensure the door is supported before removing or installing trim
• Handle edges carefully; wear gloves if trim is damaged to avoid injury
• If fasteners or clips are missing/damaged, replace them with manufacturer-recommended hardware

This wire rack provides a sturdy, corrosion-resistant shelf surface to support food containers, pans and other items inside the compartment. It restores usable storage space and helps keep items organized and level. What it does

• Replaces a bent, broken or missing wire shelf so items sit flat and don't slide or tip
• Supports dishes, trays and food containers for safe storage and even airflow
• Maintains proper spacing for drawers and other interior components to operate
• Visible wear or rust on the wires can cause sharp edges or instability

• High-level swap: remove any items, lift out the old rack and set the new rack into the existing support grooves or clips
• No special tools typically required; gentle pressure may be needed to seat rack into supports
• If rack has mounting clips, confirm clips are intact and positioned correctly before use
• For safety, avoid forcing parts;

This thermo disc is a small temperature-sensing switch that helps monitor and control appliance temperatures to protect components and support proper operation. It fits into the appliance's temperature circuit and responds at a designed trip point. What it does

• Senses temperature and opens or closes an electrical circuit at its rated trip point
• Helps prevent overheating by interrupting power when temperatures exceed the design threshold
• Supports proper temperature control for timed cycles or safety systems
• Commonly used in temperature-regulation and safety applications inside appliances

• One thermo disc

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Replace only with the exact part number for proper function and safety
