Dacor Range Error Code F30

F30 on a Dacor range indicates a shorted temperature sensor or shorted temperature sensor wiring circuit. The oven's control board is detecting abnormally low resistance from the temperature sensor, which prevents accurate temperature measurement. The oven will not operate normally until the faulty sensor or damaged wiring is repaired or replaced.

No, you should not attempt to use the oven while the F30 code is active. A shorted temperature sensor means the control board cannot accurately monitor oven temperature, which could lead to overheating or unpredictable operation. Discontinue use of the oven until the sensor or wiring fault is diagnosed and corrected.

If the oven temperature sensor itself has failed, replacement sensor parts typically range from $30 to $80 depending on the specific Dacor model. If professional labor is needed, total repair costs including the part and service call generally range from $150 to $300. Wiring harness repairs or control board replacement, if required, can push costs toward the higher end of that range or beyond.

A knowledgeable DIYer can often diagnose and fix this error by testing the oven temperature sensor with a multimeter and replacing it if it reads near zero ohms. The sensor is typically accessible from inside the oven cavity and secured with one or two screws. However, if the fault is in the wiring harness inside the oven walls or near the control board, professional repair is recommended to ensure safe handling of the wiring.

Resetting the range by cutting power at the breaker may temporarily clear the F30 code, but the error will return as soon as the oven attempts to operate again and reads the shorted sensor circuit. A reset does not fix the underlying electrical fault in the sensor or wiring. The root cause must be repaired before the code will stay cleared.
