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 oven heating element replaces a failed bake element to restore even, reliable oven heat for baking and roasting. It's a direct-replacement style part that heats the oven cavity when the bake function is used. What it does

• Heats the oven cavity during bake cycles so food cooks evenly
• Commonly used when the oven won't reach or hold baking temperatures
• Can fail visibly (broken or burned) or electrically (open circuit)
• Works with the oven's temperature control to maintain set temperature

• Disconnect power at the breaker before starting any repair to avoid shock.
• Handle the element carefully; connectors and terminals can be fragile.
• Confirm wire terminal fit and secure mounting; replace only with the correct OEM-style element.

Evaporator fan motor that circulates cold air over the evaporator coil to help maintain even refrigerator temperatures. Replacing a failing motor restores airflow, reduces warm spots and frost buildup, and cuts down on excessive fan noise. What it does:

• Spins the evaporator fan blade to move cold air through the evaporator and into the cabinet.
• Promotes even cooling to prevent warm zones and food spoilage.
• Stops or reduces abnormal noises caused by a worn or seized motor.
• Helps prevent frost accumulation linked to poor airflow.

• Disconnect power to the appliance before beginning any repair.
• Handle the motor and fan blade carefully; ensure the fan blade is seated properly on the shaft.
• Remove evaporator/fan housing panels and retain screws and clips for reassembly; verify wiring connectors match before reconnecting.

This spacer sets the correct gap between mating parts in your appliance's assembly, preventing rubbing and misalignment. Replace a missing or worn spacer to restore a solid fit, reduce noise, and protect surrounding components.

• Maintains proper spacing between components for correct alignment and operation
• Reduces metal-to-metal contact, squeaks, and premature wear
• Helps fasteners and panels seat securely
• Typical symptoms when failed: loose or rattling parts, uneven gaps, or visible wear marks

• Disconnect power; for gas models, shut off the gas. Allow the appliance to cool completely.
• Access the assembly per your model's diagram; note the original orientation/stack-up before removal.
• Reuse original fasteners if serviceable; hand-start threads and tighten snugly to avoid damaging the spacer.
• Verify alignment and clearances before fully reassembling. Quantity and location vary by model.

This heat-resistant insulation helps contain oven heat and shield surrounding components. Replacing worn insulation supports faster, more consistent preheating, steadier baking temperatures, and cooler exterior panels for safer, more efficient operation. What it does:

• Wraps/lines the oven cavity or panels to reduce heat loss and protect nearby wiring and controls
• Helps the oven preheat efficiently and maintain consistent cooking temperatures
• Limits heat transfer to exterior panels and surrounding cabinetry
• Common signs of failure: longer preheat times, temperature swings, unusually hot sides/back, or insulation that is burnt, brittle, soaked, or missing

• 1 insulation piece

• Disconnect power and, if applicable, shut off gas before servicing
• Access typically requires removing rear/side panels or sliding the unit out; take photos to aid reassembly
• Wear gloves and a dust mask; handle gently—do not compress insulation and keep clear of sensors/wiring
• Re-secure with original clips/tape, reinstall panels, then test preheat and check for abnormal exterior heat

This high-temperature insulation is used in the oven assembly to contain heat and protect nearby components and cabinetry. Replacing damaged insulation helps the appliance maintain set temperatures and keeps exterior surfaces from getting excessively hot. What it does:

• Replaces insulation that is torn, charred, or saturated with spills/grease

• One insulation piece

• Disconnect power; for gas models, also shut off the gas supply
• Remove the range or wall oven and access the oven body
• Wear gloves, eye protection, long sleeves, and a dust mask; fibers can irritate skin and lungs
• Reinstall in the same orientation/routing as the original; do not compress insulation or block vents

This interior refrigerator lamp provides illumination inside the fresh food compartment so you can see food clearly. Restores normal fridge lighting when the original bulb or socket fails. What it does:
