The lights are flashing on the Cintrol Panel. Most of the time it is just the Normal and heavy duty lights. Someimes the others flash. I have been able to fix the problem by turning off the power and re-seeding the ribbon cable on the control board. This fis would work for a while (1 week) but then i would have the same problem. Now my fix no longer works. Is my problem really the connection between the ribbon cable and the control board, or is the real problem the control panel? Please help!
