Runaway Temperature

Whenever you select an oven temperature, the heating elements are commanded to rise until that temperature is reached. If your Frigidaire electric range senses that the temperature is going beyond acceptable limits, the F10 code will display and the range will automatically shut off to prevent damage. The oven will not come on until the temperature cools significantly. If this happens repeatedly, you can severely damage your oven.

RTD Sensor Probe

A faulty RTD sensor probe is one of the causes for an F10 code or overheating oven. The sensor probe is supposed to detect the exact temperature in the Frigidaire electric range cavity and relay it to the oven’s main control so it knows when to shut off the heating elements. Follow your wiring diagram to find the probe’s location, which can differ among the models. Inspect it for any obvious damage such as cracks or tears in the wiring.

Resistance Check

If the probe appears to be intact, it could be broken internally and giving faulty information. Check it for ohms resistance by using a multimeter. Disconnect your oven’s power and follow the probe’s leads to the connecting points. Disconnect those and turn your multimeter to read ohms resistance. Place the red and black probe to each of the terminals. At room temperature, the probe should typically read around 1,100 ohms. If your reading is far above or below that, your probe needs to be replaced.

Thermostat

Other possible causes for an F10 overheat code include a bad thermostat, which is connected to your Frigidaire electric range’s temperature controls. A faulty thermostat could command the elements to heat beyond capacity if it isn’t correctly reading the temperature control’s limits. You can also test that for resistance in the same manner as the sensor probe, except you should get a “zero” or infinity rating.
