Oven temperature is consistently too hot or too cold compared to the set temperature.

Safety first: Use caution when working around a hot oven.

• Verify with thermometer: Place an oven-safe thermometer in the center of the oven and run a 350°F (177°C) bake cycle for at least 20–30 minutes. Compare the reading to the set temperature.
• Adjust calibration: Many Whirlpool ovens allow temperature calibration via the settings menu. Adjust the offset (e.g., ±30°F) according to your user manual to match the actual temperature.
• Check sensor: If the error is large or inconsistent, test the oven temperature sensor resistance at room temperature (~1080–1100 Ω). Replace if out of spec.
• Inspect door gasket: Check the door gasket for gaps, tears, or flattening that could cause heat loss. Replace the oven door gasket if damaged.
