hi I was broilng sausage when the F10 light came on- model # FGEF3035RFA! I can't ge the code off

Hello,

If you got that error while the range was in use it means that the control detected a runaway temperature, which means the range is not cycling the oven at the set temperature. In most cases that is caused by a bad temperature sensor in the oven. If you have an ohmmeter and know how to use it, follow the instructions on the page linked below

If you do not have a meter then just order and replace the temperature sensor as that is most likely the problem, however, if that does not fix it, the main control has failed. The parts for your model to fix that error are linked below.
