PURPOSE: A temperature control device is provided to prevent a fire due to the malfunction and heat of a triac by supplying power to a load across two traics in parallel. CONSTITUTION: A first photo triac(130) and a second photo triac(140) are connected to a control unit in parallel. A first triac(150) supplies external power to a load(190) connected to a heater and is connected to the first photo triac. A second triac(160) is connected to the second photo triac. A triac temperature sensor senses the temperatures of the first triac and the second triac. A control unit(120) controls external power supplied to the load.
