Pilot thermocouples are essential parts of your equipment because they measure your oven’s temperature and ensure foods are being cooked appropriately. It’s also important to have properly operating flame sensors, which confirm that the pilot light is lit whenever the gas valve is open. Ultimately, if any of these parts are broken, your oven may be unsafe to operate and even more issues can arise in the long run.
