Kenmore Range Error Code F30

F30 on a Kenmore range means the Electronic Oven Control board has detected an open circuit in the RTD temperature sensor probe circuit. The board is not receiving a valid resistance signal from the probe, which prevents it from monitoring oven temperature. The code appears when the oven is running or when you try to start a cooking function. The cause is usually a broken wire, loose connector, or a failed sensor probe.

You should not attempt to use the oven while F30 is active. The control board cannot read oven temperature, which means it cannot regulate the heating elements properly. Operating the oven in this condition creates a risk of overheating. Surface burners on a gas or electric range may still function, but the oven should remain off until the fault is diagnosed and repaired.

If only a wiring repair or connector reseating is needed, costs are minimal, typically just your time. An RTD sensor probe replacement generally runs between $20 and $60 for the part, depending on the model. If the EOC control board is the root cause, board replacement can cost anywhere from $100 to $300 or more for the part alone. Professional labor charges will add to these figures depending on your location and service provider.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the display, but F30 will return as soon as you try to use the oven again if the underlying fault is still present. The code is triggered any time an active mode is attempted with an open probe circuit. A reset is only useful for ruling out a one-time control glitch, not for resolving a wiring or sensor problem.

Start by unplugging the range and inspecting the wiring harness connected to the RTD sensor probe for any visible breaks, burn marks, or disconnected plugs. Reconnect or repair any loose connections you find. Next, test the probe's resistance with a multimeter at room temperature and compare the reading to the probe resistance chart for your model. If the resistance is out of range, replace the RTD sensor probe. If wiring and the probe both test correctly, the EOC board may need to be evaluated.
