Microwave Performance Test

Follow the below steps to test the performance of your microwave:

  1. Place a glass bowl (preferably a 2qt. glass measuring bowl) with 1qt. of water in the center of the microwave cavity. The water must be 59-75 degrees Fahrenheit (15-24 degrees Celsius).
  2. Heat the water for exactly 2 minutes 30 seconds on High (this is the default setting).
  3. A temperature rise in the range of 28-40 degrees Fahrenheit (15-22 degrees Celsius) indicates that the oven is cooking properly.
