thank u , repair-man I did what u said (Braeker on-off) and still blinking making no sense . so i decide to take out the stove and open it-up , looks good to me. no burn mark or scraths. so I spray lot of ELECTRICAL CONTAC CLEANER all over the circuit board and let it dried. now works perfect. , for how long is going to work ?? any input of what was the problem.?
