What should I do if an error code flashes in the display?

If 'F—and a number or letter' flash in the display and the oven control signals, this indicates a function error code. Press the CLEAR/OFF pad, allow the oven to cool for one hour, then put the oven back into operation. If the function error code repeats, disconnect all power to the oven for at least 30 seconds and reconnect. If the error code repeats again, call for service.
