Overview

This OEM pressure switch tubing (part number 1178417) is the factory sensing line that connects the pressure switch to the inducer/collector box on the ICP/Tempstar/Heil WPG4604130RKB1. The tubing carries the negative pressure signal that tells the pressure switch the inducer is moving combustion air and that the vent is clear, which is required before the control board will allow ignition. Cracked, kinked, melted, or moisture-clogged tubing is a leading cause of nuisance pressure-switch lockouts where the furnace clicks, runs the inducer, then fails to light. Replacing aged tubing with the correct OEM line restores a reliable pressure signal and proper ignition sequencing.

Compatibility

Direct OEM sensing line for the ICP/Tempstar/Heil WPG4604130RKB1 packaged unit and other WPG-series models that use the same pressure switch and inducer assembly. Confirm routing length and port fitment against your original tubing before installing.

Installation Guide

Safety First — Disconnect power and shut off the gas supply, then verify zero voltage with a multimeter.
Access — Remove the service panel to reach the pressure switch and inducer/collector box.
Document — Photo the tubing routing and both port connections before removing anything.
Remove — Pull the old tubing off the pressure switch port and the inducer/collector box fitting, noting any clips or grommets.
Install — Route the new tubing the same way with no kinks or low spots, and seat it fully on both ports.
Test — Restore gas and power, run a heat cycle, and confirm the pressure switch closes and the burners light.

Signs You Need a Replacement

Furnace runs the inducer but locks out on a pressure-switch fault.
Visible cracks, kinks, melting, or hardening of the tubing.
Moisture or debris trapped inside the line.
Intermittent ignition that improves when the tubing is wiggled or replaced.

Frequently Asked Questions

Does this Pressure Switch fit my ICP WPG4604130RKB1 — OEM Sensing Line | Ships Today?

Yes. This is the factory-specified OEM pressure switch for the ICP WPG4604130RKB1 — OEM Sensing Line | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the pressure switch on my ICP WPG4604130RKB1 — OEM Sensing Line | Ships Today?

Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.

My furnace shows a pressure switch error. What do I replace?

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Is this pressure switch compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP pressure switch?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
