CALIBRATION OF OVEN THERMOSTAT

The oven thermostat control is carefully calibrated at the factory so that its dial settings closely match actual oven temperatures. Field recalibration is seldom necessary, and should not be resorted to unless considerable experience with unexpected cooking results definitely proves that the control is not maintaining the temperatures to which the dial is set.

Do not recalibrate the oven thermostat until after the oven bypass flame has been adjusted (see previous procedure).

When checking the oven temperature, use a test instrument or a reliable mercury thermometer positioned in the center of the oven. The oven bottom must be in place. For convection ovens, the blower baffle must be in place.

Proceed as follows:

1.Place the thermometer or the thermocouple of the test instrument on an oven rack in the center of the oven.

2.Remove the thermostat knob and push out its metal insert (see Figure 13 on page 27).

3.Replace the thermostat knob and turn it to the 400°F (200°C) mark. Check that the oven burner comes on.

4.After oven burner has been on about 15 minutes, check the oven temperature. Open the oven door for as short a time as possible. Use a flashlight, if necessary, to see the thermometer or test instrument clearly.

5.Continue to check the temperature at five-minute intervals until two successive readings are within 5°F (3°C) of each other. If successive readings continue to vary too much, first check the bypass-flame level. If the temperature still will not stabilize, replace the oven thermostat.

6.If the stable, measured oven temperature is in the range 390°F to 410°F (194°C to 226°C) it is not necessary to change the thermostat calibration. If it is outside of the temperature range, continue with this procedure.

7.Look into the thermostat knob to see the calibration screw in the stem (see illustration on page 27). Arrows near the screw indicate which way to turn the screw to make the oven temperature higher or lower. If necessary, scrape the paint seal off the screw. While holding the thermostat knob firmly to prevent the stem from turning, insert a screwdriver through center of the knob, push the calibration screw inward, and turn the screw in the appropriate direction that will increase or decrease the oven temperature to make the measured temperature agree with the dial setting. Turn the screw only in small increments until the stable, measured oven temperature is in the range 390°F to 410°F (194°C to 226°C).

8.Turn the thermostat knob to the 450°F (230°C) mark. Allow the oven to heat until two successive readings made five minutes apart are within 5°F (3°C) of each other. If the stable, measured oven temperature is now in the range 440°F to 460°F (224°C to 236°C) it is not necessary to further adjust change the thermostat calibration. If the oven temperature cannot be set correctly, replace the thermostat.

9.Replace the knob insert that was removed in Step 2.
