Trane RSS498013 Adjustable Air Pressure Switch Kit

Product Description

The TRANE RSS498013 is a universal adjustable air pressure switch kit designed for use in gas furnace and air handler applications. The switch monitors negative pressure generated by the inducer motor and proves that proper draft conditions exist before allowing the control board to continue the ignition sequence. The adjustment range of 1.0 to 4.0 inches water column makes this kit a flexible replacement option across a wide range of residential and light-commercial heating systems. Licensed HVAC technicians install this component as part of routine furnace service or safety-control replacement.

This kit is suited for residential and light-commercial gas furnace installations where the original pressure switch has failed or is out of calibration. The adjustable setpoint allows a single kit to cover multiple furnace configurations, reducing the need to stock several fixed-setpoint switches. Technicians working on single-stage and two-stage induced-draft furnaces will find this kit applicable in many common service scenarios. Always verify the required operating setpoint against the equipment nameplate or service manual before making final adjustments.

Key Features

• Adjustable pressure range of 1.0 to 4.0 inches water column covers a wide variety of furnace applications
• Universal kit design reduces the number of individual replacement parts needed in a service vehicle
• Monitors inducer motor draft to prove safe combustion conditions before ignition proceeds
• Intended as an OEM-style replacement for failed or out-of-calibration pressure switches
• Compatible with induced-draft gas furnace control systems requiring standard pressure-switch sensing

Compatibility

Designed as a universal OEM-style replacement air pressure switch kit for induced-draft gas furnaces requiring an adjustable setpoint within the 1.0 to 4.0 inches water column range. Consult the equipment nameplate and service documentation to confirm fitment before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with the equipment manufacturer's service documentation and applicable local mechanical codes. Disconnect power to the furnace and allow the inducer motor to come to a complete stop before removing the existing pressure switch or any connected tubing. Verify that all pneumatic tubing connections are secure and free of cracks or blockages before restoring power. Set the adjustable setpoint to match the value specified on the furnace rating plate or in the original equipment service manual.
