Armstrong Furnace R06428D457 Inducer Blower Kit with Pressure Switch

Description

The Armstrong Furnace R06428D457 is an OEM-quality inducer blower kit designed as a direct replacement for compatible Armstrong furnace models. This complete kit pairs a draft inducer blower assembly with an integrated pressure switch, delivering a matched solution that simplifies service calls and helps restore furnace operation quickly.

Why the Inducer Blower Matters

The draft inducer motor is responsible for drawing combustion gases through the heat exchanger and exhausting them safely out of the flue. A properly functioning inducer is critical for efficient combustion, safe venting, and overall furnace reliability. When the inducer fails or degrades, the furnace may lock out on safety, produce error codes, or fail to ignite entirely.

Integrated Pressure Switch

This kit includes a factory-matched pressure switch that monitors the negative pressure (draft) created by the inducer blower. The pressure switch confirms adequate airflow before allowing ignition to proceed, acting as a key safety interlock. Because the blower and pressure switch are supplied together as a kit, technicians can be confident in component compatibility and calibration right out of the box.

Key Features

• Complete inducer blower kit with matched pressure switch included
• OEM Armstrong Furnace replacement part (SKU: R06428D457)
• Designed for direct, drop-in replacement on compatible Armstrong furnace models
• Pressure switch provides critical draft-proving safety interlock prior to ignition
• Helps restore furnace operation and eliminate nuisance lockouts caused by inducer or pressure switch failure
• Simplifies troubleshooting by replacing both components simultaneously

Application

This kit is intended for use in Armstrong furnace models that utilize a draft inducer blower with a pressure switch safety circuit. Always verify compatibility with the specific furnace model and serial number before installation. Refer to the furnace wiring diagram and service manual for proper installation procedures.
