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.
