Hello from JA My name is Woody. I will be glad to assist you today. I have been servicing ALL Major Brands of Appliances for 33 Years, and have over 100,000 in home repairs and over 50,000 phone and internet repairs under my belt.
The C39a is a control board error .there is no way to reset the error the control /claock has to be replaced

If the issue is the oven control board why don't the burners work??? I would think that the control board might be another part?? Please advise
Have you checked fro proper voltage to the range ,when you said nothing worked I assumed you ment the control / oven
Check where the cord attaches to the range .
the power line outside was cut one leg was not getting 120 v you were correct
