Calibrating your Imperial convection oven’s thermostat ensures accurate cooking temperatures and reliable kitchen performance.

Follow these straightforward steps:

Step 1: Assess Initial Temperature

  • Check the oven’s current temperature compared to its set temperature.
  • Identify how much adjustment is needed (for example, 30 degrees below target).

Step 2: Remove the Oven Dial

  • Carefully pull the dial off the thermostat shaft.

Step 3: Locate the Adjustment Screw

  • Find the flathead adjustment screw inside the thermostat shaft.

Step 4: Adjust the Thermostat

  • Use a flathead screwdriver to turn the screw:
    • Counterclockwise (left) increases temperature.
    • Clockwise (right) decreases temperature.
  • Hold the shaft steady while turning the screw.

Step 5: Recheck the Temperature

  • Replace the dial and set to desired temperature (e.g., 400°F).
  • Verify using an oven thermometer, ensuring accuracy within 15 degrees of the set temperature.

Summarized Overview:

Proper calibration of your oven thermostat improves cooking precision and reduces energy waste. Regularly checking and adjusting keeps your kitchen running smoothly and efficiently.

Helpful Tips:

  • Always calibrate using a reliable oven thermometer.
  • Small adjustments at a time are recommended to prevent overshooting your target temperature.
  • If the knob is equipped with a removable center plate, remove it. Place it back on the stem without the center plate. Insert a screwdriver and hold the adjustment screw in place (don’t let it move!) And turn the knob to match the actual temp.
