Introduction
A faulty temperature sensor can leave your oven stone-cold or turn it into a cremator. Replacing the sensor restores accurate heat control so your food bakes as intended. Follow this procedure to swap the plug-type sensor found in many built-in ovens and the capillary-tube thermostat used in older freestanding stoves.
