⚠️ BEFORE YOU START

Unplug the range or flip its breaker. The sensor circuit is low-voltage but lives next to 240V wiring.

Tools

  • Nut driver
  • Multimeter
  • Oven thermometer ($10, for verification)

Parts

  • Temperature sensor (RTD probe) for your model

Step by step

  1. 1 Verify with a thermometer first

    Hang a $10 oven thermometer, set 350°F, and check after 20 minutes. Within ~25°F is normal (use the oven’s calibration offset instead); 50°F+ off points at the sensor.

  2. 2 Test the sensor

    Unplug the range, find the thin probe at the cavity’s upper rear, and measure resistance at its connector: roughly 1080–1100 ohms at room temperature on most ovens. Far off = replace.

  3. 3 Unscrew and withdraw

    Two screws hold the probe’s flange to the back wall. Pull it into the oven cavity until the connector appears, then unplug it. Don’t lose the wire into the insulation.

  4. 4 Fit the new probe

    Connect, feed the wiring back, and screw the flange home.

  5. 5 Re-verify

    Same thermometer test — the dial and the thermometer should now agree within ~15°F. Fine-tune with the calibration setting if you like.

🔧 WHEN TO CALL A PRO

If a new sensor reads right but temps still swing wildly, the control board’s relay is cycling badly — board-level work worth a pro’s meter. If you'd rather skip it entirely, find a oven & range repair pro near you →
