ICP Pressure Switch Tubing for WPG4244060RKB1 — OEM 1178417 | Ships Today

Overview

This OEM pressure switch tubing (part number 1178417) connects the inducer assembly to the pressure switch on ICP WPG4244060RKB1 packaged units, transmitting the negative draft signal the switch needs to prove airflow before the burners light. Over time this small hose can crack, harden, kink, or fill with condensate — any of which prevents the pressure switch from closing and locks the furnace out on ignition. Symptoms include the inducer running but no ignition, the unit short-cycling on a pressure-switch fault, or a flashing diagnostic code indicating an open pressure switch. Replacing aged tubing with the correct OEM hose restores reliable proving and ignition.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before servicing.
2. Access — Remove the burner/control compartment service panel.
3. Document — Photograph the tubing routing between the inducer port and pressure switch before disconnecting.
4. Remove — Pull the old hose off the inducer barb and the pressure switch port, noting any condensate or cracks.
5. Install — Press the new tubing fully onto both barbs, matching the original routing with no kinks or low traps.
6. Test — Restore power and verify the inducer starts, the pressure switch closes, and the burners light normally.

Signs You Need a Replacement

• Inducer runs but burners never ignite
• Pressure-switch fault code on the control board
