Display was dead.
Control board 8302319 had a loose resistor in area that seemed to have drawn some excess current. Repaired connections to ckt board and display retored.
However, This appeared to be a symptom not the root cause.
Upper and lower oven now work as does clock. Display has multiple orange lines accross the face and difficult to view some of the digits. Display seems to be drawing higher than normal current.
I assume the control board is bad and will have to be replaced. Does anyone repair these boards? Seems a shame to throw away the whole board when it appears to be a display sub-board problem.
