Why is my GE microwave heating and heating sound does not come on? ?

Your "heating sound" is probably the sound of the fan that should cool down the magnetron.
It looks like that fan may have failed, maybe a loose wire that need to be secured, or dead fan that need to be replaced.
As for the light coming on and off, that really point to a bad contact somewhere.
The two may or not be related.

There is no answer because there is no question - you may think you posted a question a short time ago but if you examine the Most Recent list you will see that you did not...

As for answers that depends on the good nature of a person willing to reply - there is no obligation to answer any question.

As for you specific microwave issue you would do best to summon up a microwave doctor - do not attempt to repair it yourself - danger lurks inside.

Good Luck...
