Frigidaire Magnetron

The Magnatron is an OEM part for Frigidaire microwaves. It is the principal electronic component responsible for converting electrical energy into microwave radiation, allowing for fast and efficient cooking or heating of food.

Causes can be related to normal component fatigue over extended use. High voltage magnetron coils are also susceptible to power fluctuations or surges over time.

Symptoms of a faulty magnatron include:

• Inability of the microwave to transmit energy and heat foods
• Slow or ineffective cooking times
• Oven light working but no microwave output
• Overheating, arcing or burning smells from the unit

This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.

This microwave magnetron generates the energy that heats food in the oven cavity. Replacing a failed magnetron often restores normal heating.

• Produces microwave energy to heat food inside the cavity
• Typical failure symptom: microwave runs but does not heat
• Can cause loud humming or buzzing during operation
• May trip a breaker or blow a fuse at the start of a cook cycle

• Disconnect power before servicing; for built-in/OTR units, switch off the circuit breaker.
• The high-voltage capacitor can retain a dangerous charge—discharge it using the proper service procedure.
• Handle the ceramic antenna/insulator carefully and avoid overtightening mounting screws.
• Reinstall airflow shrouds/ducts and transfer any reusable brackets or thermal devices from the original part as required.

High-voltage magnetron that generates microwave energy to heat food in the oven cavity. Replacing a failed magnetron restores heating when the microwave runs but food doesn't warm. What it does:

• Converts high-voltage power into microwave energy to heat food in the oven cavity.
• Commonly needed when the microwave motor and lights run but the unit fails to heat.
• A failing magnetron can cause unusual noises, intermittent heating, or a burning odor.
• Critical high-voltage component — faults can create arcing or other dangerous conditions.

• Disconnect power and unplug the appliance before accessing the microwave cavity.
• High-voltage capacitor may retain a lethal charge—do not attempt capacitor discharge unless qualified.
• Handle the magnetron by the housing, avoid touching ceramic antenna or terminals.

The Magnetron is an OEM part for Frigidaire microwave ovens. Located behind the waveguide plate inside the microwave chamber, the magnetron generates electromagnetic waves to cook and heat food. Powered by a high-voltage transformer, a magnetron coil focuses 2.45GHz radio waves through the waveguide into the cavity.

Causes of a bad magnetron can include failures of the cathode filament or insulator over extended use, depletion of filament or high voltage components.

Symptoms of a bad Magnetron include:

• Slow or incomplete cooking even on high power 
• Discolored or burnt spots on food
• No visible arcing yet cavity runs continuously
• Oversparking sounds or burning smells from chamber

This genuine OEM Frigidaire magnetron is compatible with Electrolux, Gibson and some Kenmore microwave models as well.

This magnetron converts high-voltage electrical energy into microwave energy to heat food in a microwave oven. Replacing a failed magnetron restores cooking power and eliminates cold or uneven heating. What it does:

• Generates the microwave radiation that cooks food inside the oven cavity
• Restores normal heating when a burned-out magnetron causes no-heat or weak heating
• Addresses symptoms such as loud arcing, a burning smell, or no microwave output
• Works with the oven's high-voltage circuit and waveguide to deliver microwaves to the cavity

• Disconnect power and allow capacitors to fully discharge before servicing; high-voltage risk is present even with the unit unplugged
• Inspect and replace any damaged waveguide covers or high-voltage components when present
• Use correct mounting hardware and gasket alignment to avoid arcing or microwave leakage

This magnetron is the high-voltage microwave source used in countertop and over-the-range ovens to heat food. Replacing a failed magnetron restores the oven's ability to generate microwave energy for cooking. What it does:

• Generates microwave energy that heats and cooks food inside the oven cavity.
• Commonly needed when the oven runs but does not heat, or heating is very weak.
• May be replaced if you hear loud buzzing, intermittent heating, or experience arcing/sparking inside the cavity.
• Works with the oven's high-voltage circuit and waveguide to distribute microwaves evenly.

• One magnetron (single unit as shown)

• High-voltage component: always disconnect power and discharge the capacitor before service.
• Inspect and replace any damaged waveguide cover, seals, or mounting hardware; secure all connections and shielding per OEM instructions.
• Follow all safety warnings in the oven's service manual and dispose of the old magnetron according to local regulations.
