How to Calibrate Your Oven Temperature

Accurate oven temperature is essential for consistent cooking. If your recipes are not turning out right, temperature calibration may be needed.

Testing Oven Temperature

What You Need

Oven-safe thermometer (not the pop-up type)

30 minutes

Testing Procedure

Place thermometer in center of oven

Set oven to 350°F

Wait 20-30 minutes for full preheat

Check thermometer reading

Compare to set temperature

Acceptable Variance

±10°F is typically acceptable

±15-25°F warrants calibration

±25°F+ may indicate component issues

Calibrating Most Ovens

Digital Controls

Enter calibration mode (consult manual)

Adjust offset based on test results

Save new settings

Retest to verify

Mechanical Controls

Older ovens may require physical adjustment of the thermostat, typically a professional task.

When Calibration Is Not Enough

If temperature varies widely during cooking or cannot be calibrated within range, components may need repair:

Temperature sensor

Thermostat

Control board
