Adjustment of Oven Thermostat
The oven thermostat is carefully calibrated at the factory so that the dial setting matches the actual oven temperature. Field
recalibration is seldom necessary, and should not be resorted to unless considerable cooking experience definitely proves that
the control is not maintaining the temperatures to which the dial is set.
Obtain a test instrument or a reliable mercury thermometer, then do the following:
1. Place the thermocouple of test instrument or the thermometer in the middle of the oven.
2. Turn on the oven and set the thermostat to 400°F.
3. After the oven has been on about 20 minutes check oven temperature. The oven door should be open for as short a time
as possible. Use a flashlight, if necessary, to see the thermometer clearly.
4. Continue to check the temperature at 5-minute intervals until two successive readings are within 5 degrees of each other.
The thermostat should be recalibrated if the reading is not within 20 degrees of the dial setting (400°F). If calibration is
required, adjust the thermostat, as follows:
5. Remove the oven temperature control knob. Be careful to not turn the stem (which would change the temperature setting).
6. While holding the stem in place, turn the calibration screw (see drawing below). If the actual measured temperature is lower
than the dial setting, turn the screw counterclockwise. If the measured temperature is higher than the dial setting, turn the
screw clockwise. Replace the control knob.
7. Set the oven temperature to 450°F. After about 20 minutes, check the oven temperature. Continue to check the
temperature at 5-minute intervals until two successive readings are within 5 degrees of each other. If the actual oven
temperature is not within 20 degrees of the dial setting (450°F), replace the thermostat.
Calibrate the thermostat by holding the
shaft in place while turning the screw
counterclockwise to increase the temperature,
or clockwise to decrease the temperature.
With the control knob removed,
the control shaft will extend out
of the control panel.
