Oven temperature too hot or too cold compared to set temperature; food overcooks or undercooks.

Safety First: Use an accurate oven thermometer to verify temperature before replacing parts. Turn off power before accessing internal components.

Step-by-step:

• Verify temperature: Place an oven thermometer in the center of the oven. Preheat to 350°F and allow 15–20 minutes. Compare actual temperature to the set temperature.
• Adjust calibration: Many Premier EOCs allow temperature adjustment (e.g., ±35°F). Refer to your manual to enter calibration mode and adjust up or down based on your test.
• Inspect sensor: If calibration cannot correct a large error (over 35°F), test the oven sensor resistance at room temperature. Replace the oven temperature sensor if out of specification.
• Check door gasket: Inspect the oven door gasket for gaps, tears, or flattening. Replace if damaged to prevent heat loss.
