Kenmore / Sears Capacitor

Microwave not heating? High voltage capacitor stores energy to power the magnetron. DIY repair typically takes 30-60 minutes with proper safety care.

Microwave not heating or making loud buzzing noise? This high voltage capacitor stores and releases power to the magnetron. Moderate DIY repair.

Fix a microwave that won't heat or makes loud humming noises. This high voltage capacitor often fails when the magnetron can't generate heat properly.

This replacement shield is a direct-fit protective cover that restores the appliance's factory protection for internal components. It prevents contact with sensitive parts and helps keep wiring and controls clear of debris. What it does:

• Protects wiring, controls and nearby components from heat, moisture and debris.
• Restores the original barrier that helps prevent accidental contact with moving or hot parts.
• Replaces cracked, broken or missing shields that can lead to rattling, exposed components or interference.
• Helps maintain appliance safety and quiet operation when installed correctly.

• One replacement shield

• Always disconnect power to the appliance before starting any repair.
• Handle replacement shield carefully — edges may be sharp; use gloves and basic hand tools.
• Retain and reuse original fasteners unless new hardware is specified; ensure shield is properly seated and secured.
• Do not operate the appliance with shields or covers missing.

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

If your microwave won't power on or runs intermittently, a faulty capacitor may be the cause. This part stores electrical charge for the magnetron.

Fix a refrigerator that won't cool or has a humming compressor with this running capacitor. Restores smooth motor operation and prevents overheating.

Fix a washer that won't start or hums but doesn't spin with this capacitor. Common fix for motor starting issues. Moderate DIY repair in 30-45 minutes.
