Haier oven temperature is inaccurate, food undercooked or overcooked compared to set temperature

Safety first: Use an oven thermometer to verify temperature; avoid touching hot surfaces.

• Verify temperature: Place an accurate oven thermometer in the center of the oven and preheat to 350°F (175°C). Compare the displayed temperature with the thermometer reading.
• Adjust calibration: Many Haier models allow temperature offset adjustment in the settings menu (e.g., +/- 35°F). Follow the user manual to calibrate.
• Inspect door gasket: Check the oven door seal for gaps, tears, or compression. Replace the oven door gasket if damaged.
• Sensor check: If large discrepancies persist, test the oven temperature sensor resistance at room temperature and replace if out of spec.

Allow the oven to fully preheat and avoid opening the door frequently, as this affects temperature stability.
