Look for the code inside the manual. They usually have troubleshooting codes in them!!

control circuit problem

It could possibly be you are not getting 240 volts to the range. The top igniter may be getting a current back through the other side of the 240 circuit and that is why it works when the oven is turned on but the oven will not be getting power to heat. Have the 240 circuit checked or make sure the circuit breakers are reset correctly.

Gas or electric oven?

"This oven is equipped with a state of the art electronic oven control. Among its many features is a full time oven circuit diagnostics system. The control constantly monitors its internal circuitry as well as several crucial oven circuits to insure they are all operating correctly. If at any time one of these systems fails, the control will immediately stop operation, and beep continuously (flashing an error code of F1, F3 or F9 in the display window, if equipped). Electronic control has detected a fault condition. Press CLEAR to clear the display and stop the beeping. Reprogram oven. If fault recurs, record fault number, press CLEAR and contact an authorized servicer."
