Kenmore Range Error Code F9

A voltage supply problem could prevent all elements in the range from heating. See if the lower oven elements and surface burners heat. If no elements heat, check the house circuit breakers because the range may be getting only 120 volts instead of the 240 volts needed to power the heating elements. Reset both circuit breakers for the range because it’s often difficult to tell whether a breaker tripped. If the range elements don’t heat after resetting the breakers, unplug the range and check the power cord wire connections on the terminal block. Reconnect any loose wires. Replace the power cord if you find damage. If you find no problems with the power cord or circuit breakers, then you’ll likely need to have a service technician diagnose and repair the problem because the technician will need to perform live voltage checks that are dangerous if not performed correctly. If only the upper oven elements won’t heat, unplug the range and check the wire harness connections between the upper bake element and the relay control board. Reconnect any loose wires and repair any broken wires. Measure the resistance of the upper bake element using a multimeter. You should measure near 27 ohms of resistance through the upper bake element. Replace the bake element if you measure infinite resistance. If the upper bake element is okay and you find no wiring problems, check the resistance of the upper oven temperature sensor. You should measure 1090 ohms at room temperature (77 degrees F). If resistance is off by more than 100 ohms, replace the upper oven temperature sensor.
