Frigidaire Range Error Code F30

Open RTD sensor probe or wiring problem (open condition in probe circuit)

Frigidaire codesFrigidaire range codes

Open RTD sensor probe or wiring problem (open condition in probe circuit). EOC may initially display F10 thinking a runaway condition exists.

First step from the service manual

Check wiring in probe circuit for possible open condition. Check RTD resistance at room temperature (compare to probe resistance chart). If resistance does not match the chart, replace the RTD sensor probe.

The complete diagnostic procedure includes additional test steps, resistance specifications, wiring diagram references, and component test points.

What F30 means on a Frigidaire range

The F30 error code indicates the Electronic Oven Control (EOC) has detected an open circuit in the RTD sensor probe connection. An open circuit means the control board is receiving no signal from the probe, which typically points to a broken sensor, a disconnected connector, or a damaged wiring harness between the EOC and the probe. The board requires a continuous resistance reading from the RTD sensor to regulate oven temperature; when that signal is absent, it throws F30 and halts normal oven operation.

The RTD (Resistance Temperature Detector) sensor probe is a small component mounted inside the oven cavity that measures temperature by changing its electrical resistance as heat increases. Your range relies on this constant feedback loop to know when to cycle the heating elements on and off. When the connection is broken anywhere along the path from the probe tip to the control board, the oven has no way to monitor temperature and will not operate safely.

F30 can be triggered by a failed sensor probe, a loose or corroded connector at either end of the wiring harness, or a wiring harness that has been damaged by heat or physical wear over time. The condition is specific to an open circuit, meaning the resistance reading is infinite or absent rather than simply out of range.

Common causes of F30

  1. 01

    Failed RTD sensor probe

    Part replacement

    The RTD sensor probe itself has developed an internal open circuit, producing no resistance reading at all. This is the most common cause of F30 and can be confirmed by measuring resistance at the probe terminals with a multimeter and comparing to the RTD resistance chart.

  2. 02

    Disconnected or loose sensor connector

    Wiring / connection

    The wiring harness connector at the RTD sensor probe or at the EOC has come loose or pulled out, breaking the electrical circuit entirely. This can happen from vibration over time or from a previous repair where the connector was not fully seated.

  3. 03

    Damaged wiring harness between EOC and sensor probe

    Part replacement

    The wiring harness running from the EOC to the sensor probe can develop breaks, burns, or chafed insulation that creates an open circuit. Heat exposure inside the oven cavity is a common cause of harness degradation over years of use.

  4. 04

    Faulty Electronic Oven Control (EOC)

    Part replacement

    If the sensor probe resistance checks out correctly and the wiring harness and connectors show no faults, the EOC board itself may have a failed input circuit that cannot read the sensor signal. This is the least likely cause and should only be suspected after the sensor and harness have been ruled out.

Frequently asked questions about F30

What does the F30 error code mean on a Frigidaire range?
F30 means the Electronic Oven Control has detected an open connection in the RTD sensor probe circuit. The control board is receiving no resistance signal from the temperature sensor, which prevents the oven from monitoring or regulating heat. The fault can originate at the sensor probe itself, the wiring harness, or a connector between the probe and the EOC.
How do I fix the F30 code on my Frigidaire range?
Start by unplugging the range and locating the RTD sensor probe inside the oven cavity, typically mounted on the back wall. Disconnect the sensor and measure its resistance with a multimeter at room temperature, then compare the reading to the RTD resistance chart in your service manual. If the resistance does not match, replace the sensor probe. If the sensor reads correctly, inspect the wiring harness and connectors between the sensor and the EOC for damage, breaks, or loose connections.
Can I still use my Frigidaire range if the F30 code is showing?
The oven portion of the range will not operate safely with an active F30 code because the control board cannot monitor oven temperature without a functioning sensor signal. Surface burners on a gas range may still ignite, but you should not attempt to use the oven until the fault is resolved. Continuing to attempt oven use with this code active will not damage the range further, but it will not heat correctly.
How much does it cost to fix an F30 error on a Frigidaire range?
An RTD sensor probe is the most common fix and typically costs between $20 and $50 for the part, making it one of the more affordable oven repairs. If the wiring harness is damaged, harness assemblies generally range from $30 to $80. If the EOC board is the root cause, board replacement can cost $150 to $300 or more for the part alone. A technician diagnostic visit typically adds $80 to $150 in labor.
Is the F30 code on a Frigidaire range a difficult repair to do yourself?
Replacing the RTD sensor probe is considered one of the easier oven repairs for a DIY homeowner. The probe is accessible from inside the oven cavity, usually held in place by two screws, and connects to the wiring harness with a simple plug connector. Testing the sensor with a multimeter before purchasing parts is recommended. Replacing the wiring harness or EOC board requires more disassembly and comfort with appliance wiring, so professional service is advisable for those repairs if you are not experienced.
