Kenmore Oven Error Code F30

F30 indicates an open circuit in the RTD temperature sensor probe circuit. The oven's electronic control board is not receiving a valid resistance signal from the probe, which prevents it from monitoring oven temperature. The cause is typically a broken wire, a failed RTD probe, or in less common cases, a faulty control board. The code appears only when the oven is in or attempting to enter an active cooking mode.

No, you should not attempt to use the oven while F30 is active. The oven's control board cannot read temperature without a functioning RTD circuit, meaning it has no way to regulate or limit heat. Continuing to operate the oven in this condition could create an uncontrolled heating situation. Resolve the fault before resuming normal use.

Repair cost depends on which component has failed. An RTD sensor probe is generally an inexpensive part, with DIY repair costs typically ranging from $15 to $50 for the part alone. Professional labor to diagnose and replace the probe can bring the total to $100 to $200. If the analog control board requires replacement, parts costs range from roughly $100 to $300 or more depending on the model, with professional repair potentially reaching $250 to $500 total.

Many DIYers can resolve F30 by inspecting the RTD probe wiring for breaks or loose connectors, and by testing the probe resistance with a multimeter. If the resistance does not match the probe resistance chart at room temperature, replacing the RTD sensor probe is a straightforward repair that typically requires only a screwdriver. If the wiring and probe both test correctly, replacing the analog control board is more involved and may warrant professional service.

A reset, such as cutting power at the breaker and restoring it, may temporarily clear the display, but the F30 code will return as soon as the oven attempts to enter an active mode if the underlying fault has not been corrected. The wiring, RTD probe, and control board must be diagnosed and the defective component repaired or replaced for the code to clear permanently.
