Calibration
Calibration Check
• Place thermometer in the center of oven cavity.
• Set thermostat to 350°F and place both 3-heat switches in the “HIGH” position.
• Allow the oven to Preheat for at least half an hour.
Cycle on temperatures and cycle off temperatures for 3 cycles.
(Red indicator light indicates when oven is calling for heat)
After 3 cycles average the temperature. ( Add all six temperatures and divide by 6)
Calibration Adjustment
• A 1/16” flat blade screwdriver with a 2” shaft is required to make adjustments to the
thermostat.
• Maintain the oven temperature at 350°F.
• Without turning the thermostat, remove the knob.
• Locate the adjustment screw at the base of the shaft and insert the screwdriver.
• Hold the shaft and turn the screwdriver counter clockwise to increase the temperature and
clockwise to decrease the temperature. (1/8 of a turn will move the temperature 5-7 °F in
either direction).
• Reinstall the oven knob and recheck the oven temperature.
