Goodman 0130F00469 2-stage Pressure Switch

Product Description

The Goodman 0130F00469 is a 2-stage combustion air pressure switch designed for use in gas furnace systems. It monitors negative pressure created by the inducer blower motor to confirm proper venting and combustion airflow before allowing ignition to proceed. This switch operates at two set points: negative 0.1 inches water column and negative 0.75 inches water column, corresponding to the low-fire and high-fire stages of a two-stage furnace. It is a direct OEM-style replacement component typically installed by licensed HVAC technicians during routine service or system repair.

This pressure switch is suited for residential gas furnaces that operate on a 2-stage heating sequence. In a 2-stage furnace, the inducer motor runs at different speeds depending on the heating demand, and the pressure switch must verify adequate draft at both stages before the control board allows the gas valve to open. This part is appropriate for applications where the original switch has failed, reads incorrectly, or where a furnace is experiencing lockout faults related to draft proving.

Key Features

• 2-stage operation with dual set points at negative 0.1 and negative 0.75 inches water column
• Monitors combustion air pressure to verify proper inducer and vent performance
• Prevents ignition if draft pressure is outside the specified range, protecting the heat exchanger and flue system
• OEM-style replacement design for straightforward swap-out during service calls
• Air-sensing switch type suited for gas furnace draft proving applications

Compatibility

Designed as an OEM-style replacement pressure switch for 2-stage residential gas furnaces requiring negative 0.1 and negative 0.75 inches water column set points.

Installation Notes

Installation should be performed by a licensed HVAC technician. Before servicing, shut off power to the furnace at the disconnect switch and turn the gas supply to the off position. The pressure switch connects to the inducer housing via a rubber hose; inspect the hose and port for cracks, blockages, or moisture before installing the replacement switch. Verify that wiring terminals are fully seated and that the furnace cycles through both heating stages without fault codes after installation.
