Had a fryer in one outlet and a table top grill in a different outlet the breaker went had
To reset but it doesn't work now, it will not reset, so outlets don't work. How do we fix this problem?

Will not reset, as in trips as soon as it is reset, or will not move at all?

Did you move the breaker all the way OFF then back to ON?

Yes moved breaker all the way Off then back to On, Now What??

The Breaker needs to be replaced.
They will go bad/break.
Or you still have a short?

Is this a commercial or residential building? Did these devices work together before or is the installation brand new?

If this is a residential kitchen, then both receptacles should be protected by a GFCI device. Either a Breaker or GFCI receptacle. The circuit should be 20 amp.

What is the amperage required by the units?

Don brings up a good point. Is there a GFI involved?
When you reset breaker does it immediately trip off again or does it stay in position but you don't have power to outlets. (Stan's question)
