How to calibrate oven?
A friend asked me to help calibrate her oven. We measured it with an oven thermometer and it overheats by almost 60 degrees. Her oven is about 15 years old so it doesn't have a digital control panel, only knobs. The only ways I know to calibrate older ovens is either by adjusting the screws on the back of thermostat knob or by adjusting the screw in the shaft of the thermostat but this oven has neither. The oven is a White-WestingHouse model CWEF310ES1. Anybody know of any other to calibrate ovens?
