This magnetron capacitor is the microwave high-voltage capacitor that helps supply the magnetron with the pulse of energy needed to produce heat. Replacing a failing capacitor restores normal heating performance and reduces arcing or loud humming. What it does

• Stores and releases the high-voltage pulse required by the magnetron so the microwave can generate heat.
• Prevents unstable magnetron operation that can cause weak or no heating.
• Common symptoms of a failing capacitor: oven runs but doesn't heat, intermittent heating, loud buzzing/humming, or visible arcing inside the cavity.
• A failed capacitor can also cause blown internal fuses or tripped circuits.

• One capacitor.

• Disconnect power and verify the appliance is completely de-energized before servicing.
• Capacitors can hold dangerous charge; discharge the capacitor safely with an insulated tool.
• Use the exact replacement part and follow the appliance service manual for routing and connections.

This capacitor stores and releases electrical energy to help an AC motor start and run smoothly. Replacing a weak or failed capacitor can restore reliable motor operation and reduce humming, no-start, or stall conditions.

• Provides the phase shift and starting torque an induction motor needs to start
• Helps the motor reach and maintain proper speed under load
• Common symptoms of a failing capacitor: motor hums but won't start, intermittent starts, slow or stalled rotation, or frequent thermal trips
• Visible clues may include a swollen case or leaking residue

• Disconnect power to the appliance before servicing; verify no voltage is present
• Capacitors can retain a charge—discharge safely before handling
• Note wire positions; move leads to the new capacitor one at a time and ensure snug terminal fit
• Reuse the original bracket/clip if applicable and secure the capacitor to prevent vibration

This thermistor is a refrigerator temperature sensor that monitors internal air temperature so the control board can regulate cooling. Replaces a failed sensor to help restore accurate temperature readings and more consistent cooling. What it does:

• Senses internal refrigerator temperature and sends a variable resistance signal to the control board
• Helps the control system cycle the compressor and fans correctly for stable temperatures
• Commonly replaced when refrigerator runs too cold, too warm, or has irregular cooling cycles
• Can address temperature-error codes or defrost control issues when the sensor is faulty

• Disconnect power to the appliance before inspecting or replacing the sensor
• Handle the sensor and wiring harness carefully to avoid damage to the probe or connectors
• Install in the original sensor mounting location and secure wiring away from moving parts

The Interlock Switch is an OEM part for Whirlpool microwaves. It monitors the position of the microwave door and signals to the control board whether it is safe to operate.
