Bosch Range Error Code F30

F30 on a Bosch range means the control module has detected an open circuit in the oven temperature sensor system. The RTD probe or its wiring is not completing the circuit, so the oven cannot monitor internal temperature. The oven will not operate normally until the fault is resolved.

No, you should not use the oven while F30 is active. The error means the control module cannot read oven temperature, so there is no way for the oven to regulate heat accurately. Attempting to use the oven in this condition creates a risk of overheating.

Repair costs depend on whether the fault is a failed RTD sensor probe or a wiring harness issue. RTD sensor probes typically cost between $30 and $80 for the part. Adding professional labor, total repair costs generally range from $100 to $250. A simple connector reseating requires no parts and minimal labor cost.

A knowledgeable DIYer can diagnose F30 by measuring resistance at the two violet wires on the control module harness connector and comparing that reading to the RTD Sensor Resistance chart for the model. If the harness is intact and connectors are secure but resistance is wrong, the RTD sensor probe needs replacement. If you are not comfortable working with appliance wiring and connectors, a qualified technician should perform the repair.

Resetting the range by cycling power may temporarily clear the display, but the F30 code will return as soon as the control module attempts to read the sensor circuit again and finds the open condition. The underlying fault in the sensor probe or wiring harness must be repaired to permanently clear the error.
