Using this oven temperature sensor is easy. First, make sure your oven is turned off and unplugged to avoid any electrical hazards. Then, locate the old sensor and carefully remove it. Next, connect the new sensor with the 2 - way plug and place it in the same position as the old one. Finally, plug in your oven and turn it on. When using, don't touch the sensor directly with wet hands to prevent electrical shock. For maintenance, keep the sensor clean and free from debris. If you notice any issues with your oven's temperature control, check the sensor for damage. If it's damaged, replace it as soon as possible.
