Ksb3540bo Parts

The KitchenAid Blender Drive Coupler is an OEM part for KitchenAid blenders. This part connects the blender's motor to the blade assembly.

Causes for issues with the drive coupler often involve overloading the blender, blending hard or frozen ingredients without sufficient liquid, or simply the natural degradation of the component over time.

Symptoms of a malfunctioning Blender Drive Coupler include:

• The blender's motor running, but the blades not spinning
• Visible wear or damage to the coupler's teeth
• Unusual noises during operation, indicating a misalignment or damage

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

Color: clear. It measures about 3-1/2 inches in diameter.

This replacement seal keeps liquids and food particles out of the blender motor housing to protect internal components and help prevent leaks. Fits the motor assembly where the shaft passes through the housing. What it does

• Seals the motor shaft opening to help prevent liquid from entering the motor housing.
• Reduces risk of motor damage or shorting caused by leaks into the base.
• Helps stop leaking at the blender base or around the blade assembly when worn.
• Replace if the seal is cracked, flattened, swollen, or shows visible wear.

• Always unplug the appliance before disassembly and removal of the jar or motor housing.
• Remove the blade and jar assembly per the service diagram to access the shaft seal; inspect mating surfaces and replace damaged components.
• Ensure the new seal is seated evenly around the shaft and in its groove; do not force or over-stretch the seal.
• After reassembly, run a short water test (with the unit unplugged from any direct water source) to check for leaks before normal use.

This Foot is the support pad the appliance or a mounted component rests on, helping keep it stable and properly leveled. Replace a worn or missing foot to reduce rocking and vibration and protect surrounding surfaces.

• Provides a stable contact point between the chassis/component and its mounting surface
• Helps maintain level placement for proper alignment and operation
• Cushions movement to reduce vibration and rattling noises
• Replaces cracked, flattened, or missing feet that cause wobbling or uneven stance

• Disconnect power and shut off any water or gas supplies; move the appliance carefully with assistance
• Access the foot location; remove the old foot and install the new one securely
• Adjust height/level as needed and verify the unit is stable before use

This interlock collar assembly centers and supports the door/lid interlock so the appliance can detect and secure the door during operation. Restores proper engagement of the latch for reliable start/lock behavior and safety sensing. What it does:

• Positions and stabilizes the interlock/lock mechanism so the door or lid can latch correctly.
• Helps the appliance register a closed/locked door so cycles can start and run.
• A worn, cracked, or broken collar can lead to failure-to-start, door not locking/unlocking, or intermittent door-latch problems.
• Works with the interlock/latch components to maintain safe operation of the door/lid assembly.

• Disconnect power before attempting any service; follow basic electrical safety.
• Replacement requires access to the door/lid latch—use appropriate hand tools and avoid forcing plastic tabs.
• Inspect the interlock and latch components for additional wear; replace damaged parts as needed.
• Refer to OEM instructions for model-specific removal and reassembly guidance.

This interlock collar assembly secures the door latch area so the appliance detects a closed door and allows normal operation. It restores proper door engagement and helps prevent the unit from starting with the door open. What it does:

• Centers and supports the door latch/interlock mechanism for reliable door closure
• Ensures the door switch or interlock can engage so the appliance will start when closed
• Can cause no-start, intermittent starting, or a loose/loose-feeling door if worn or broken
• Helps stop rattling or misalignment around the latch area when functioning correctly

• Disconnect power (unplug or switch off breaker) before starting any repair
• Basic disassembly may require removing the appliance front or door trim to access the collar
• Inspect the door latch and interlock switch for wear while replacing the collar
