Oven temperature is inaccurate; food is undercooked or overcooked compared to the set temperature on a Monogram range.

Safety first: Use an oven thermometer rated for high temperatures when testing.

• Verify temperature: Place an oven thermometer in the center of the oven and preheat to 350°F. Compare the actual temperature after 20–30 minutes to the set temperature.
• Adjust calibration: Many Monogram models allow temperature adjustment in the settings menu (e.g., +/- 35°F). Follow the user manual to calibrate.
• Inspect sensor: If calibration cannot correct large errors, test the oven temperature sensor resistance and replace if out of spec.
• Check door gasket: Inspect the door gasket for gaps, tears, or compression. Replace if damaged to prevent heat loss.
