Oven overshoots the set temperature — e.g., set to 350°F but climbs to 550°F or higher. A degraded sensor sends incorrect resistance readings to the control board, causing runaway heating.
Oven fails to reach or maintain the set temperature. The sensor may have drifted out of spec, causing the EOC to cut power to the heating element prematurely.
Hot spots or cold spots during cooking. Inconsistent sensor resistance output prevents the control board from cycling the bake element correctly.
F3 or F4 fault displayed on the oven's control panel. These codes indicate an open or shorted oven temperature sensor circuit — replacing this sensor clears the code in most cases.
Electronically-controlled ovens may refuse to enter bake or broil mode when the control board detects an out-of-range sensor signal at startup.
💡 Pro Tip: How to Confirm Your Sensor Is Bad
Your part is likely the culprit if you notice any of the following:
⚠️ Oven runs but won't reach the set temperature, or continuously overshoots it
⚠️ Food is undercooked or burnt even at correct settings — uneven baking or roasting
⚠️ F3 or F4 error code displayed on the oven control panel
⚠️ Oven temperature randomly spikes (e.g., set to 350°F but climbs to 550°F+)
🔬 DIY Test: Unplug the oven and use a multimeter to measure resistance across the sensor's two terminals. At room temperature (~70°F) you should read approximately 1080–1090 ohms. A reading significantly higher, lower, or open-circuit (OL) confirms the sensor has failed and must be replaced.
