Lennox 14T65 Combustion Air Pressure Switch Kit

The Lennox 14T65 Combustion Air Pressure Switch Kit is a safety device crucial for gas-fired furnaces. It acts as a guardian by monitoring the air pressure within the furnace's combustion chamber. By maintaining proper air pressure, the combustion process functions efficiently and safely. If the air pressure falls below a safe limit, the switch triggers a shutdown of the furnace. This safety measure prevents hazards like improper combustion or flue gas backdraft, which could lead to carbon monoxide leaks or fires. The Lennox 14T65 Combustion Air Pressure Switch Kit is a single unit (measuring around 0.6lbs) and features a Single Pole Single Throw (SPST) Normally Open (N.O.) electrical contact configuration. This design makes it relatively lightweight and straightforward to install and maintain within compatible HVAC systems.
