Dacor Oven Error Code F1 — Oven Temperature Sensor Failure
What this means
Error code F1 on Dacor ovens and ranges indicates the oven temperature sensor (RTD probe) has failed or is providing readings outside the acceptable range. Dacor ovens use a precision platinum RTD sensor that measures oven cavity temperature and communicates with the control board to regulate heating. If the sensor is disconnected, has an open circuit, or is severely out of calibration, the oven cannot maintain accurate temperature and will display F1. The oven will not operate until the sensor issue is resolved.
Alternate codes: F01, Error F1
Step-by-step fix
4 stepsReset the oven
Turn off the Dacor oven at the circuit breaker for 3 minutes. Restore power and check if F1 clears. A power surge or temporary glitch can sometimes trigger a false F1 reading.
Dacor ovens may require you to press a specific button sequence after a reset to clear the error display — consult your model's manual.
Test the oven temperature sensor
Turn off power at the breaker. Open the oven and locate the temperature sensor probe — it extends from the upper rear wall of the oven cavity. Disconnect the sensor wiring connector (accessible behind the oven or at the control board). Measure resistance across the sensor leads with a multimeter. At room temperature (77°F / 25°C), a Dacor RTD sensor should read approximately 1,080–1,100 ohms.
Dacor uses high-quality RTD sensors, but they can fail from thermal stress during self-clean cycles. If you use self-clean frequently, the sensor experiences extreme temperatures.
Inspect the wiring harness
Trace the sensor wiring from the oven cavity to the control board. Look for heat-damaged insulation, loose connectors, or corroded pins. Dacor ranges with a cooktop above the oven can have wiring routed through high-heat areas where damage occurs.
Pay special attention to the wire where it passes through the oven cavity wall — this is the highest stress point for heat damage.
Replace the sensor
If the sensor reads open circuit or significantly outside the 1,080–1,100 ohm range, replace it. Remove the single or dual mounting screws from inside the oven cavity, pull the sensor and wire through the back, install the new sensor, and reconnect. Restore power and test by setting the oven to 350°F.
After installing a new sensor, allow the oven to run at 350°F for 20 minutes and verify the actual temperature with an oven thermometer to confirm accuracy.
When to call a professional
If the sensor and wiring test fine but F1 persists, the control board's sensor input circuit may have failed. Dacor control boards are premium components and should be replaced by an authorized technician.
