Kenmore Microwave 721.88519900 (72188519900, 721 88519900) 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

Replace your microwave grease filter to maintain proper ventilation and reduce odors. Filters grease and smoke from cooking. Verify fit with your model number.

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.
