i had the same problem. Firstly have you tried to reset the timer ? (press the second and third buttons together, then press + or - to set the clock) but mine kept re-unsetting its self and flashing. so following someone elses advice on here. Turn oven off at wall... i removed the cooker tops, pulled the blue wires out of the back of the timer, covered exposed conectors with electrical tape, put all back together. My ovens will now work but obviously no clock or timer.
