Description
The Lennox 80W53 is an OEM replacement pressure switch engineered for precise, reliable performance in Lennox heating systems. Designed to monitor draft pressure within the furnace, this switch helps ensure safe and efficient operation by verifying that the inducer motor is functioning correctly before allowing ignition to proceed.
Key Features
- Set point of -0.68″ water column (wc) for accurate draft pressure sensing
- SPST (Single Pole, Single Throw) switching configuration for straightforward integration
- 1/4″ barb connection for secure, leak-free hose attachment
- OEM Lennox replacement part — direct fit for compatible Lennox furnace models
- Helps protect against unsafe furnace operation due to blocked flues or inducer failure
How It Works
The pressure switch monitors the negative pressure (draft) created by the inducer blower during furnace startup. If the correct pressure level is not achieved — indicating a potential venting or inducer issue — the switch remains open and prevents the ignition sequence from continuing. This critical safety function helps protect both the equipment and the occupants of the building.
Application
- Designed for use in Lennox gas furnaces requiring a -0.68″ wc pressure switch
