Frigidaire Range Error Code F30

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.

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.

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.

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.

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.
