This door gasket is the flexible rubber seal that fits the dishwasher door to keep water inside the tub during cycles. Replacing a worn gasket restores a watertight seal and helps stop leaks and moisture buildup. What it does:

• Seals the gap between the door and tub to prevent water leaks during wash cycles
• Keeps spray and suds inside the dishwasher, protecting surrounding flooring and cabinetry
• Helps reduce odors and mold growth by maintaining a tight seal that limits moisture escape
• Common symptom: water pooling or dripping from the bottom/side of the door
• Common symptom: visible cracks, tears, flattening, or hardened areas in the gasket

• One door gasket

• Inspect the door channel and mating surfaces; clean away residue before installing the new gasket
• Press the gasket evenly into the door channel, working from one end to the other to avoid twisting
• Turn off power and water to the appliance before working on the door; refer to the service manual for model-specific instructions

This high-limit thermostat is the overheat safety switch for the heating circuit. It opens when excessive temperature is detected to cut power to the heater, protecting the appliance and restoring normal heating when replaced.

• Monitors temperature at the heater and opens the circuit if it overheats
• Helps prevent damage from excessive heat and potential safety hazards
• A failed-open thermostat may cause no heat, poor drying, or unusually long cycles
• Frequent tripping may point to underlying circulation or control issues that should be checked

• Disconnect power at the breaker or unplug the appliance; allow it to cool completely before service
• Access location per model; typically mounted on or near the heater or heater housing
• Note wire positions and transfer leads one at a time; secure using existing mounting hardware
• After installation, run a test cycle to confirm proper heating

This thermostat with attached sensing cable detects and regulates appliance temperature to help maintain proper heating cycles and protect against overheating. It replaces a failed temperature control component so your appliance can heat correctly and safely. What it does:

• Senses internal temperature and sends a signal to the control to start or stop heating
• Helps prevent overheating by providing accurate temperature feedback
• Works as the temperature-sensing element used by the appliance control board

• Disconnect power before servicing to avoid electric shock
• Handle the sensing cable and probe gently; do not kink or pinch the capillary/sensor
• Verify proper routing and secure mounting of the sensor per the appliance's service instructions

This clear replacement lens protects and covers an internal appliance light while restoring proper light dispersion and appearance. It replaces a cracked, cloudy, or missing lens to improve interior visibility and finish. What it does:

• Covers and protects the internal light bulb or LED assembly from debris and moisture.
• Restores even light dispersion for brighter, clearer interior illumination.
• Replaces cracked, chipped, or discolored lenses that cause glare or reduced visibility.
• Helps maintain original appearance and prevents direct contact with the light source.

• Disconnect power to the appliance before any service to avoid electrical shock.
• Handle the lens carefully to avoid scratching; align retaining tabs or slots before snapping into place.
• Use only the factory fasteners or clips; do not overtighten or force the lens into position.

This high-temperature 220V, 15-watt oven light bulb restores bright interior lighting so you can monitor cooking progress without opening the door. It's built for sustained heat and replaces a burned-out or flickering lamp.

• Illuminates the oven cavity during baking, broiling, and cleaning cycles
• High-temperature design for continuous heat exposure
• Common failure symptoms: no light when switched on, dim or intermittent illumination, blackened glass, or a broken filament

• Disconnect power at the breaker and allow the oven to cool completely
• Remove the light lens/cover; unthread and remove the old bulb
• Thread in the new bulb of the same voltage and wattage; do not overtighten
• Reinstall the cover, restore power, and test the light
