Kenmore Microwave 721.86019010 (72186019010, 721 86019010) Parts

This is a motor start/run capacitor that helps the appliance's motor start and run smoothly by supplying a brief boost of electrical energy. Replacing a failing capacitor restores reliable motor startup and operation. What it does:

• Provides the brief electrical surge needed to start and keep the motor running
• Commonly linked to motors that hum, fail to start, or run intermittently
• Helps prevent overheating from repeated start attempts when functioning properly
• Works with the appliance's start circuitry to ensure consistent performance

• Disconnect power to the appliance before accessing electrical components
• Discharge the capacitor and use insulated tools
• Observe polarity/terminal layout and secure connections to factory specifications
• Dispose of the old capacitor according to local electronic-waste regulations

A Tap-Tite binding-head screw used to fasten appliance panels and components where a self-tapping metal thread is required. Replaces missing or damaged fasteners to restore secure assembly and reduce vibration or rattling. What it does:

• Creates its own mating thread in thin sheet metal for a secure hold without a nut.
• Holds panels, brackets, and trim in place to prevent looseness or movement.
• Commonly used where stripped, missing, or broken screws cause rattling, misalignment, or parts that won't stay attached.
• Compatible with standard screwdrivers or nut drivers sized to the binding-head.

• Disconnect power and unplug the appliance before working on it.
• Use the correct driver bit to avoid cam-out or head damage.
• Start straight and apply steady pressure; avoid overtightening to prevent stripping the formed threads.
• If the original hole is badly damaged, assess for repair or use of a larger fastener as needed.

Size: 5 inches x 7 3/4 inches.

This turntable assembly restores smooth rotation inside your microwave so food heats more evenly. Replace a cracked tray or worn support to eliminate wobble and scraping noises while maintaining a stable, level surface for dishes.

• Supports and rotates cookware with the drive coupler during cooking
• Promotes even heating by keeping food moving through the microwave energy
• Stabilizes the tray to reduce spills, wobble, and noise
• Replaces broken, chipped, or missing glass tray and support ring

• Disconnect power and allow the microwave to cool before servicing; handle glass carefully
• Remove old tray and ring; clean the cavity floor and turntable track
• Position the roller ring on the track; align the tray with the center coupler until it seats flat
• Test with a cup of water to ensure smooth, quiet rotation

A flat washer used with the appliance's fastening hardware to distribute load and reduce wear. Helps maintain secure connections and prevents damage to mating surfaces for reliable operation. What it does:

• Provides an even bearing surface for bolts or screws to prevent pull-through
• Reduces friction and wear between fasteners and housing parts
• Helps keep fasteners tight and resists loosening from vibration
• Commonly used where a smooth, protective spacer is needed

• Verify correct location and orientation before reassembly
• Use manufacturer-recommended fasteners and torque specifications
• Power off and unplug the appliance before accessing internal components

This drive shaft transfers motor torque to the appliance drum or tub, restoring proper rotation and reducing wobble. A direct-fit replacement designed to return smooth, quiet operation when the original shaft is worn or damaged. What it does

• Connects the motor/transmission to the drum or tub so the drum can spin.
• Restores correct alignment and rotation to reduce wobbling or scraping.
• Helps stop symptoms like noisy operation, grinding, or a drum that won't turn.
• Works as the mechanical link in drive assemblies where a worn shaft prevents normal function.

• Disconnect power and water supply, and drain the appliance before beginning service.
• Access may require removing the cabinet, front panel, or tub—follow the service manual for your model.
• Use appropriate tools and follow OEM instructions for safe removal and reassembly.

A molded air guide that channels internal airflow to improve circulation and component cooling inside the appliance. Replaces a worn or broken guide to restore designed airflow paths and reduce air leaks. What it does

• Directs and channels airflow through the appliance to support proper ventilation and cooling.
• Helps maintain consistent operating temperatures by guiding air where the manufacturer intended.
• Common symptom: reduced airflow or cooling performance, longer cycle times, or inconsistent operation.
• Common symptom: rattling or vibration if the guide is cracked, loose, or damaged.

• One air guide.

• Disconnect power (and gas, if applicable) before beginning any repair.
• Inspect mounting tabs and surrounding seals; replace any damaged fasteners to ensure a secure fit.
• Handle the plastic guide carefully to avoid cracking; align tabs and press into place until seated.
• Test operation after installation; recheck for unusual noises or airflow issues.
