A heat sensor in a furnace detects the temperature inside the furnace. When the temperature reaches a certain level, the sensor signals the furnace to either turn on or off to maintain the desired temperature. This helps regulate the temperature and ensures the furnace operates efficiently by preventing overheating or underheating.
