How Do You Calibrate Gas Oven Thermostats?
If your gas oven is not cooking your food the way you desire, its thermostat may require calibration. Many ovens run at a higher or lower temperature than the user intends, which can be hard to see unless you always check your food with a thermometer. Place an oven thermometer on the center rack of the gas oven. Set the oven to 350 degrees, and let it run for a half hour. Check the oven thermometer to see whether it reads 350 degrees after the half hour is over. If the thermometer is more than 50 degrees off, the oven’s thermostat will probably need to be replaced. Minor differences can be corrected by calibrating the thermostat. Use a flathead screwdriver to lift off the temperature knob from the oven. The thermostat calibration dial will be located on the rear of the knob itself or down at the bottom of the shaft. If the calibration dial is on the back of the knob, there will be clips or retaining screws locking it in place. Loosen these clips or screws, and adjust the dial as needed
