Magnetron

This magnetron is the high-voltage tube that generates the microwave energy used to heat food in compatible microwave ovens. Installing a new magnetron restores microwave heating when the tube has failed. What it does:

• Converts high-voltage electrical energy into microwave radiation to heat food
• Restores heating when oven powers up but does not heat or has weak heating
• Addresses humming, arcing/ sparks, or blown microwave fuses caused by a failed tube
• Works as the core microwave source; must be used with intact waveguide and protective cover

• One magnetron (quantity: 1)

• High-voltage components retain lethal charge; disconnect power and discharge the capacitor before service
• Inspect and replace any damaged waveguide cover or high-voltage wiring when installing
• Do not operate the microwave with the outer cover removed; follow OEM torque and mounting instructions

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

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.

This duct-magnetron (waveguide duct) directs microwave energy from the magnetron into the oven cavity and helps protect internal components. Replacing a damaged duct restores proper wave guidance and prevents arcing or burn damage. What it does:

• Channels microwaves from the magnetron into the cooking cavity for even energy transfer
• Shields surrounding components from heat and sparking that can occur with a cracked or warped duct
• Helps prevent arcing, burning smells, and visible sparks inside the microwave
• Maintains proper alignment between the magnetron output and the oven waveguide

• One duct-magnetron (waveguide duct) as shown

• Unplug the appliance and ensure power is disconnected before servicing
• Microwave high-voltage components can store lethal charge; discharge capacitors and follow safety procedures
• Handle carefully to avoid bending or further damaging the duct; wear gloves and eye protection
