Lennox Furnace Pressure Switch OEM Replacement

The Lennox furnace pressure switch is an OEM replacement part for Lennox gas furnaces. It is also called an air pressure switch, draft inducer pressure switch, or vacuum switch. It monitors airflow and draft from the inducer motor and confirms proper venting before the furnace lets the burners ignite.

Key Features:

• Genuine Lennox OEM replacement design for reliable fit and function
• Diaphragm-style switch that opens and closes in response to pressure changes from the inducer motor
• Prevents burner ignition if the inducer is not creating proper draft, which helps keep the furnace operating safely
• Helps resolve common problems such as a furnace that will not ignite, short cycling, or an inducer that runs without the burners firing
• Built for dependable performance through repeated heating cycles

Several models are available in this product line. Each one is matched to a specific Lennox furnace application, so choose the part number that corresponds to your furnace's original switch. Replacing a failed or worn pressure switch with an OEM part helps restore dependable furnace operation.
