Description

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

What's included:

• One magnetron

Install notes:

• 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 part fixes the following symptoms

• Noisy
