My microwave does not seem to be cooking foods?
Microwave specs: GE® 30" Built-In Double Microwave/Thermal Oven JTP90DPBB. This microwave is just 1.5 years old. The light in the microwave goes on and off as the door of the microwave opens and shuts. The light is also on when you put in cook time etc. The power shows 10. But the food inside does not seem to be getting cooked. The last time I used it for heating up a glass of water in a glass container-which worked. After which immediately I was heating up a glass of coffee again in a glass container-it did not work. I do not see how it could just stop working like that. Am I missing something here?
Is there any trouble shooting button?
