I have a Dacor Epicure Millennia Pure Convection Double oven that is 8 yrs old. I am no longer able to reset the clock by pushing the clock button. The clock still runs but the time is not correct and I can not change it by pushing the button. Do you know if this is a part I can replace myself or if I need a service technician to do it. I called one service company and they said it would cost about $350 for the part and labor to replace the membrain (?) that controls the clock function. That seems very high to me. Any suggestions would be greatly appreciated. Thanks.
