Kenmore Elect Built-IN Oven Model 790

Question

Oven control beeps and displays F code error - will not re-program. House had major power surge and oven was disconnected while new service we installed. This oven had only been used 3 or 4 times. We purchased it new in fall 2004. Unfortunately this oven is in our house in Mexico, state of Sonora, near Navajoa and there are no Sears repair services nearby. PLEASE HELP! Thank you
