Capacitor

This washer motor run capacitor stores and releases electrical energy to help the drive motor start and run smoothly. Replacing a weak capacitor can help restore consistent agitation and spin and reduce motor humming or stalling under load.

• Provides the phase shift and torque assist the drive motor needs to start and stay running
• Can address: washer won't start, no agitate or spin, motor only hums/buzzes, or stops under load
• Visible clues of failure can include a swollen, cracked, or leaking capacitor case

• Unplug the appliance before servicing; capacitors can retain a charge even when power is off
• Discharge the capacitor safely before handling
• Note wire positions; move leads to the same terminals and secure the capacitor in the original bracket/orientation
• Inspect connectors and replace any burnt or loose terminals to ensure a tight fit

Fix a microwave that won't heat or blows fuses. This high-voltage capacitor powers the magnetron. Moderate DIY repair, requires careful discharge.

Microwave stopped heating or makes humming noise before shutting off? The high voltage capacitor often fails first. DIY repair in under 30 minutes.

This is a high voltage capacitor used in the microwave's magnetron circuit. It stores and releases electrical energy to help power the magnetron, which generates the microwaves that heat food. Replace this capacitor if the microwave runs but does not heat, hums loudly without cooking, or if the capacitor has visibly bulged or leaked. Always discharge the capacitor before handling, as it can retain a dangerous charge even when unplugged.

Dryer hums but won't start or spin? A failed capacitor prevents the motor from activating. This part sends the electrical jolt needed to start your dryer.

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.

Microwave won't heat or makes humming noise? This capacitor works with the magnetron to generate heat. Moderate difficulty repair, 30-45 minutes.

Microwave not heating? This high-voltage capacitor stores and releases electrical energy to power the magnetron for heat production. DIY fix.

Fix a dryer motor that won't start or hums without spinning with this motor start/run capacitor. Restores the electrical boost needed for smooth operation.

Fix a microwave that runs but won't heat with this capacitor. Works with magnetron and diode to restore heating function. Moderate DIY repair.

189-227 MFD, 125 VAC

This is an oil-filled high-voltage capacitor used in the microwave's magnetron circuit. It stores and releases electrical energy to help power the magnetron, which generates the microwaves that heat food. Replace this capacitor if the microwave runs but does not heat, hums loudly without heating, or if the capacitor has visibly bulged or leaked oil.

This motor capacitor helps start and run appliance electric motors by providing the brief boost of power the motor needs to reach operating speed. Replaces a failed capacitor to restore normal motor starting and performance. What it does:

• Provides the electrical phase shift and momentary voltage boost motors need to start and run
• Commonly replaced when a motor hums, will not start, or runs weakly
• Helps stabilize motor operation and reduce hard starting stresses
• Resolves intermittent or failed motor startup symptoms when capacitor is the root cause

• Disconnect power to the appliance before accessing or replacing the capacitor
• Discharge stored voltage in the capacitor before handling to avoid shock
• Verify terminal connections and orientation match the original before installation

Microwave won't heat? A faulty capacitor often causes no heating or weak performance. This high-voltage capacitor restores full power. Moderate DIY.

If your microwave runs but won't heat, a failed magnetron capacitor may be the cause. This high-voltage component stores energy for the magnetron.

If your microwave won't heat food or makes buzzing sounds, the high voltage capacitor may have failed. This part stores electrical energy for the magnetron.
