Kitchenaid K45ss Parts

Mixer won't run or just hums? Worn motor brushes in the holder cause power loss. This DIY repair restores full motor function on stand mixers.

The Grey Thumb Screw is an OEM Replacement Part designed for securing attachments on 4.5 and 5 Whirlpool and KitchenAid quart mixers. This screw plays a critical role in ensuring the stable and secure connection of various mixer attachments. With a user-friendly design, it offers easy installation without the need for additional tools. It can be installed by hand-screwing.

This genuine replacement gear is a drivetrain component that transfers motor rotation to a mating mechanism inside your appliance. Replacing a worn or stripped gear restores smooth, reliable motion and helps prevent damage to adjacent parts.

• Meshes with adjacent gear(s) or a shaft to drive an internal mechanism
• Worn or rounded teeth can cause slipping, skipping, or no movement
• Intermittent or stalled movement can indicate a stripped or damaged gear

• Disconnect power (and shut off water/gas if applicable) before servicing
• Access the assembly; note orientation and timing marks
• Transfer any spacers, keys, or retaining clips from the old gear
• Seat the new gear fully and verify smooth manual rotation before restoring power

If your mixer makes excessive noise or vibrates during operation, a worn spring seat cap may be the cause. This part centers and secures springs for smooth, quiet performance.

If your stand mixer runs only on high speed or won't change speeds properly, a worn governor drive stud may be the cause. This small repair restores smooth speed control in about 30 minutes.

This cap spring is a small coil that supplies the return tension a cap or button needs to operate smoothly. Replace it if weakened, bent, or missing to restore proper feel and reliable engagement of the mechanism.

• Maintains spring tension under a cap/button to keep parts aligned
• Helps the cap return smoothly and prevents looseness or rattling
• Supports consistent engagement of the related control or latch
• Typical signs of fatigue: loose or wobbly cap, sticking action, poor return, or a spring that pops out

• Disconnect power and shut off water/gas supplies before servicing
• Note the spring's orientation and stack-up; take photos as you disassemble
• Use needle-nose pliers and control the spring so it doesn't eject
• Seat components fully and test operation before final reassembly

Fix a mixer that won't turn on or has burnt electrical smell. This motor field assembly controls variable speed. Replaces worn electrical components.

White plastic back cover for stand mixers. Protects internal components at rear of motor housing. Replace if cracked, broken, or missing.

This bearing supports a rotating shaft or assembly inside the appliance, reducing friction for smooth, quiet operation. Replacing a worn bearing restores proper alignment and helps prevent noise and premature wear on connected parts.

• Provides a low-friction surface for smooth rotation
• Helps keep the rotating component centered and stable
• Reduces vibration and operating noise
• Common failure signs: grinding/squealing, wobble or play, rough or intermittent rotation

• Disconnect power; also shut off water or gas supply if applicable
• Access the assembly per your model's service information and note part orientation before removal
• Inspect the shaft/hub and any spacers or seals for wear; replace related worn components
• Seat the bearing squarely—do not force; apply only manufacturer-specified lubricant if called for in service literature

Replace your mixer's wavy spring washer to reduce vibration and noise. This washer maintains proper tension between shaft components for smoother operation.

If your mixer runs intermittently or loses power, a cracked or missing brush holder cap may be letting the carbon brush slip. Simple threaded repair.

Fix a mixer that won't start, slows down, or makes grinding noises. This armature (motor rotor) restores reliable operation when worn or burned.

Fix intermittent mixer operation or arcing sounds with this brush holder housing. Secures carbon brushes for steady motor contact and consistent speed.

This headless, cup-point set screw secures a component to a shaft or hub inside your appliance. The 1/4-28 x 3/8 in size bites into the mating surface to prevent slipping, helping keep collars, pulleys, or knobs aligned and stable.

• Locks a hub, collar, or pulley to a shaft to prevent movement
• Helps maintain alignment and reduce wobble or vibration
• Replaces missing, stripped, or damaged set screws
• Common signs include components slipping on a shaft, rattling noises, or recurring loosening

• Disconnect power before servicing
• Clean threads and align with any flat on the shaft before tightening
• Start threads by hand to avoid cross-threading; tighten securely without overtightening
• Recheck tightness after a brief test run

This 6-32 machine screw fastens brackets, panels, and internal components in your appliance. Replacing a missing or stripped screw restores a secure, rattle-free fit and keeps assemblies properly aligned during normal operation.

• Secures components to frames, brackets, or covers
• Helps maintain proper alignment of panels and hardware
• Replaces missing, damaged, or stripped fasteners
• Common signs: loose/rattling panels, misaligned parts, or a screw that won't tighten

• Disconnect power (and water, if applicable) before servicing
• Match thread and length to the original fastener; reuse any washers if present
• Start threads by hand to avoid cross-threading; tighten snugly without overtightening
• Use the driver that matches the head style on your original screw

• Thread size: 6-32 (machine screw)

This is a flat washer used in the drive assembly of a stand mixer. It sits between moving components to reduce friction and prevent wear on mating surfaces. Replace this washer if the mixer is making unusual noises, vibrating excessively, or if the original washer is worn, cracked, or missing.
