Kenmore / Sears Range / Cooktop / Oven Magnetron

This microwave high-voltage capacitor stores and releases energy in the high-voltage circuit to power the magnetron. Replacing a failed capacitor helps restore proper heating and protects other components in the high-voltage system.

• Works with the transformer and high-voltage diode to supply the magnetron with the required voltage
• Failure may result in the unit running but not heating
• Shorted capacitors can blow the internal fuse or trip a breaker; opens may cause loud humming or buzzing
• Visible swelling or leakage on the capacitor body are common failure signs

• Unplug the microwave; capacitors can retain a dangerous charge even when unplugged—discharge using an appropriate, insulated method before servicing
• Note wire positions and terminal orientation; transfer any mounting hardware from the original part
• Mount securely and route wires to avoid pinching

This motor start/run capacitor helps the compressor and fan motors start and run reliably, restoring normal cooling performance when a failing capacitor causes hard starts or intermittent motor operation. A direct-replacement component for affected units. What it does:

• Provides the electrical phase shift and stored energy needed for compressor and fan motor startup.
• Helps prevent slow starts, humming, or motors that won't start reliably.
• Restores stable motor operation and can reduce overheating or tripping caused by a weak capacitor.
• Works as a replacement for the same OEM-design capacitor in compatible refrigerators and freezers.

• One replacement capacitor (single unit)

• Disconnect power to the appliance before inspecting or replacing the capacitor to avoid shock.
• Verify capacitor is fully discharged before handling; use insulated tools and follow safety procedures.
• Match the capacitor's mounting and terminal type to the existing part for correct fit and connection.

This magnetron generates microwave energy to heat food in compatible countertop and over-the-range microwaves. Replacing a worn magnetron restores cooking power and helps eliminate uneven heating or failure to heat. What it does:

• Converts high-voltage electrical power into microwave radiation used to cook and reheat food
• Common symptom: oven runs but food doesn't heat or heats very slowly
• May also be needed if you notice loud buzzing, arcing, or burning odors during operation
• Works with the microwave's high-voltage system; other components may also need inspection

• One magnetron (single unit as shown)

• Disconnect power and discharge the microwave's high-voltage capacitor before servicing
• Inspect surrounding parts (waveguide, diode, capacitor, and cooling fan) for damage during replacement
• Use only the correct replacement part number to ensure proper fit and safe operation
