Dacor Range Error Code Oven On Indicator Light blinks once every 2 seconds

This blinking pattern indicates the oven temperature sensor circuit is open, meaning the control board is not detecting any resistance signal from the sensor. The oven cannot measure its internal temperature and will not operate until the fault is resolved. The first diagnostic step is to measure the sensor resistance at controller board connector P2, which should read between 1050 and 1100 ohms at room temperature.

The oven itself will not heat while this fault is active, so there is no immediate safety risk from the oven overheating. However, you should not attempt to bypass or ignore the fault, as the open sensor means the oven has no way to regulate its temperature. Surface burners on a gas or electric range may still function, but the oven should remain unused until the sensor circuit is repaired.

Replacement oven temperature sensors for Dacor ranges typically cost between $30 and $80 for the part alone, depending on the specific model. If a technician is performing the repair, total costs including labor generally range from $100 to $250. Costs can be higher if the issue involves wiring harness repair or control board replacement rather than just the sensor probe.

A knowledgeable DIYer can perform the initial resistance check at board connector P2 using a multimeter to determine whether the sensor, wiring, or connector is at fault. If the sensor reads open or far outside the 1050 to 1100 ohm specification, replacing the sensor probe is a manageable repair that involves removing the old probe from the oven cavity and reconnecting the new one. However, if the fault traces to the control board or internal wiring harness, professional service is recommended.

Resetting the range by cycling power at the breaker will not clear this error if the underlying sensor circuit fault still exists. The control board will re-detect the open circuit on the next power-up and resume the blinking indicator. The fault will only clear once the sensor, wiring, or connector issue is physically corrected and the circuit reads within the proper resistance range.
