How To Test a Microwave For Leaks

Microwave radiation leakage is rare but does happen. Here’s how to test your appliance.


  • Step 1: If you don't take your microwave to a repair shop, contact your state health department or local Food and Drug Administration field office.
  • FACT: Did you know? The Food and Drug Administration has regulated the manufacture of microwave ovens since 1971.
  • TIP: A repair service must have state-legislated testing equipment, and must notify state agencies of any leaks.
  • Step 2: Take your microwave to a repair professional. Repair services have the proper tools to gauge leak hazards.
  • Step 3: Unplug your microwave, put your cell phone inside, close the door, and call it from another phone. If it rings, you have a leak.
  • Step 4: Visually inspect your microwave for possible signs of leakage, such as dust in the door seals.
