Hi, I have a Technika Freestanding Cooker GHE09TDSS-4 gas cooktop with electrical oven. I have had nothing but trouble with the oven. I've had the control panel replaced twice and the cooker is on 5 1/2 years old and I've come home from work and now there is absolutely no power to the oven at all but the clock is working fine. Do you have any suggestion other than tossing the useless piece of crap?
