Additionally, it protects the internal components of the furnace; running a system with low pressure can cause the heat exchanger to overheat and crack, leading to expensive repairs or replacements. Key Functions and Safety Roles The primary role of this component is to prevent life-threatening hazards.
Understanding Furnace Pressure Switch Safety Component Importance
The pressure switch is connected to two ports: one that senses the pressure from the blower and another that vents to the outside of the flue. This movement creates a specific range of positive air pressure inside the venting system.
When the furnace initiates a heating cycle, the blower motor activates to push air through the heat exchanger. Identifying a Faulty Component Maintenance and Troubleshooting While the switch itself is not a consumable part that wears out like a filter, the components around it require attention to ensure it functions correctly.
Understanding Furnace Pressure Switch Safety Component Importance
If the heat exchanger cracks or the venting is obstructed, harmful gases can leak into the living space. One of its most critical functions is to guard against the buildup of carbon monoxide (CO).
