Dacor Range E2 Error: Sensor circuit out of range
This dacor range e2 error code guide explains what this fault means for your Dacor appliance and how to respond safely. What E2 Means on a Dacor Range E2 on a Dacor range signals the oven temperature sensor circuit is producing a reading outside the allowable range during active cooking. Unlike F1 (fully open sensor) […]

Answer to continue safely
Is it safe to keep using?
Maybe. The oven heats but temperature readings are unreliable. Use an oven thermometer and monitor closely.
Can I reset the code?
Yes. Reseating the sensor connector and power cycling sometimes resolves intermittent E2 faults.
When to stop immediately?
Stop if you notice: Do not use the oven for temperature-sensitive cooking — inaccurate temperature control is both a food-safety and fire concern., Stop if E2 appears on every cook cycle — the sensor requires physical replacement, not repeated resets..
Symptoms You May Notice
Oven temperature varies widely from the set point
An independent oven thermometer confirms the actual cavity temperature swings more than 50°F above or below the set temperature on a consistent basis.
E2 appears mid-cycle, not at startup
Unlike F1 or F3 which trigger at startup, E2 typically appears during a cooking cycle after the oven has been running for 15-20 minutes — the sensor drifts once it reaches operating temperature.
Baking results are inconsistent from use to use
The same recipe produces different results each time because the oven temperature varies between uses, even at the same setting.
Code clears on cancel but returns within one cook cycle
Pressing Cancel clears E2 temporarily, but the code returns within the next bake session — the underlying sensor drift is not resolved by a simple cancel.
Possible Causes
RTD sensor drifting at operating temperature
The sensor reads correctly at room temperature (passes the 1080-ohm cold test) but drifts significantly at 350°F or higher. This failure mode is not caught by a static resistance test and requires dynamic testing.
DIY PossibleCorroded or loose sensor connector
The connector between the RTD probe and the wiring harness has developed corrosion or a loose pin, creating intermittent contact that causes the resistance reading to fluctuate during heating cycles.
DIY PossibleSafe Checks You Can Do
-
1
Reseat the RTD sensor connector
With the range unplugged, locate the RTD probe at the rear of the oven cavity (two mounting screws, rear wall). Disconnect the wiring connector, inspect the pins for corrosion or bending, and firmly reseat. Also reseat the connector at the control board end if accessible.
A light spray of electrical contact cleaner on the connector pins followed by reseating can clear corrosion that causes intermittent contact.

Verify temperature with an independent thermometer
Place a calibrated oven thermometer at the center rack position. Set the oven to 350°F and after 20 minutes note the actual temperature. A deviation greater than 35°F from the set point, combined with E2, confirms the sensor is the source of the fault.
Test at multiple temperatures (350°F, 400°F, 450°F) — a drifting sensor often gets worse at higher temperatures.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Connector reseated and cold test passes (1080 ohms) but E2 returns after 20 minutes of cooking — sensor is drifting at temperature and must be replaced.
- New sensor installed but E2 persists — control board sensor input circuit requires professional diagnosis.
