Hello paigeh, I can understand your concern about the error code. The information you have received is good. The F13 indicates a problem with the EOC (Electronic Oven Control board). This can be caused by a power surge or glitch through the electrical supply lines. You can try disconnecting electrical power completely from the range by unplugging it. Leave it unplugged for a few minutes. If the fault code returns when you plug the range back in, then the EOC will need to be replaced. For more specific information reply with the full model number and we will be glad to assist you further.
