Electrical shortage

Hello,

I had an over the stove microwave installed 2.5 years ago and the installer added an electrical outlet to my kitchen to pwr the microwave. I am not sure how he wired it but I think he wired it to another outlet in the kitchen. I recently had a problem with the microwave shutting down before the time set on the microwave was completed. The microwave would go completely dead and then after a few minutes would turn back on. I checked the outlet and there was no electricity. I checked another outlet on the same wall to the right of the microwave and there is no electricity their either. I ran an extension cord from the microwave to a GFI outlet and the microwave works fine. I check the breakers and cannot find one that is tripped. I replaced the outlet to the microwave and still no electricity. How would I go about finding the problem with these 2 outlets?

Thanks,

Glenn

Re: Electrical shortage

At first I thought an overheat protection device in the microwave was shutting off the unit.
But if the entire circuit is dead then either the breaker went bad or a wire is loose somewhere.

Re: Electrical shortage

This is a longshot: the microwae circuit is slightly overloaded and tripped a breaker. But, the toggle handle didn't slam to the off position as it would do with a direct short.

Try cycling all the 15A & 20A breakers off then back on.

If that doesn't work, reset all the GFCI receptacles you can find.

But, if ***** actually came back on ,as you say "The microwave would go completely dead and then after a few minutes would turn back on. I checked the outlet and there was no electricity", you probably have a loose connection feeding the microwave that only shows itself after heating up.
If so, check the box the electrician connected to.
