Hi @charles82655
Was there a power outage just prior to the problems appearing on the oven?
What is the complete model number of the oven?
Asking as there are three models i.e. JTD3000SN1SS, JTD3000SN2SS & JTD3000SN3SS and they may not be all exactly the same as far as parts are concerned.
I can't find a download of the mini manual online (GE p/n 31-2000513) which may help to find out exactly what is wrong (control board issue perhaps?) but here's an [https://products.geappliances.com/appliance/gea-support-search-content?contentId=16290|article] that may help you to find it in your oven or if it isn't there to hopefully get one from the manufacturer.
