Kenmore / Sears Microwave Magnetron

The Magnetron is an OEM part for LG microwaves. As the primary cooking mechanism, it generates microwave energy to heat and cook foods quickly.

Causes can be from normal wear and tear over years of use. Damage may also occur if the microwave interior is exposed to moisture, spills or debris.

Symptoms of a faulty magnetron include:

• Slow or ineffective cooking
• Hot or cold spots in cooked foods
• Buzzing or humming noises emanating from inside the microwave

This OEM LG part is also compatible with some Kenmore models.

The Magnetron is an OEM part for Whirlpool microwaves. This part generates the microwave energy necessary for cooking and heating food.

Causes of a bad Magnetron can include normal wear and tear over time, power surges or electrical issues, or physical damage from impact or mishandling.

Symptoms of a bad Magnetron include:

• The microwave not heating or cooking food properly
• Arcing or sparking inside the microwave cavity
• Strange noises or buzzing sounds during operation
• Burning smells or smoke coming from the microwave

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

A replacement magnetron assembly that generates the microwave energy used for cooking and reheating. Installs in countertop and over-the-range microwave ovens to restore normal heating performance when the magnetron fails. What it does:

• Produces high-frequency microwave energy that heats food inside the oven cavity.
• Commonly replaces a unit when the microwave stops heating or heats very weakly.
• Can address symptoms like no/poor heating, intermittent heating, or loud humming from the oven during operation.
• Not a control or capacitor—this part is the microwave-generating tube and works with the oven's HV system.

• Always disconnect power and unplug the appliance before starting service.
• The high-voltage capacitor can retain a dangerous charge; discharge properly.
• Handle the magnetron carefully; avoid touching terminals or the antenna.
• Follow OEM instructions and safety guidelines for reassembly and testing.

This magnetron is the microwave's high-voltage tube that generates the microwaves used to heat food. Replacing a faulty magnetron restores heating performance and stops power-related cooking failures. What it does:

• Converts high-voltage electrical energy into microwave radiation that heats food
• Common symptom: microwave runs but does not heat
• Also be needed if you notice humming, arcing, or a burning electrical smell during operation
• Works with the oven's high-voltage system and waveguide to deliver cooking power

• Disconnect power before servicing; microwave high-voltage components can retain lethal charge
• Discharge the high-voltage capacitor and follow safety procedures
• Inspect waveguide cover and surrounding components for damage when replacing the magnetron

This magnetron is the high-voltage microwave tube that generates the microwave energy used to cook and reheat food in your oven. Replacing a failing magnetron restores heating performance when the rest of the microwave system is functioning. What it does:

• Generates microwave energy that heats food inside the oven cavity
• Common symptom: unit powers on but does not heat
• May also cause loud humming, burning smell, or arcing when failing
• Works with the oven's high-voltage circuit and waveguide to deliver even cooking

• One magnetron

• High-voltage component — disconnect power and discharge the capacitor before service
• Avoid touching terminals or the ceramic insulators; handle by mounting brackets
• Verify other high-voltage components (diode, capacitor, transformer) and seals to ensure safe operation
