Gas Furnace Components Quiz

Gas Furnace Components

• Heat Exchanger: Transfers heat between two substances, ensuring efficient heating within the furnace.
• Induced Draft Motor: Responsible for venting flue gases produced during fossil fuel combustion, contributing to safety and efficiency.
• High Limit Switch: A safety mechanism that ensures furnace operation remains within a designated temperature range, preventing overheating.
• Gas Valve: Regulates and controls the flow of gas into the burners, critical for safe and efficient operation.
• Burners: Final component for delivering gas or gas-air mixtures to the combustion zone, crucial for effective heating.
• Circuit Board: Manages the sequence of operations necessary for the furnace's proper functioning, coordinating various components.
• Blower and Blower Motor: A centrifugal fan powered by a motor that circulates air throughout the heating system, enhancing air distribution.
• Flue Pipe: Conducts flue gases from the combustion process out of the furnace, essential for ventilation and safety.
• Door Switch: A safety feature that disables the furnace when the access door is removed, protecting users from accidental exposure.
• Rollout Switch: Stops furnace operation if flames escape the combustion chamber, acting as a critical safety device.
• Flame Sensor: Utilizes various technologies (heat, infrared, light) to detect flame presence, ensuring fire safety and operational accuracy.
• Transformer: Modifies voltage within the system to ensure compatibility with various electrical components.
• Pressure Switch: Opens and closes based on pressure changes, part of safety and operational protocols within the furnace system.
