Customer Questions and Answers for Magnetron (Microwave Oven) by Whirlpool

This magnetron generates the microwave energy that cooks food inside a microwave oven, restoring heating performance when the original tube fails. Replaces a failed magnetron to return proper cooking and reheating. What it does:

• Converts electrical power into microwave energy used to heat food.
• Restores normal cooking when the oven no longer heats or has weak heating.
• Resolves loud humming, sparking, or intermittent heating caused by a failing tube.
• Works with the oven's high-voltage circuitry and waveguide to distribute energy into the cavity.

• Disconnect power and unplug the appliance before service; high-voltage components can retain a dangerous charge.
• Discharge the high-voltage capacitor before touching the magnetron or associated wiring.
• Inspect and replace any damaged waveguide covers or mounting hardware for safe operation.
