Overview

This OEM pressure switch tubing (part #1178417) is the hose that connects the draft inducer and vent system to the pressure switch on the ICP / Tempstar / Heil WPG4364060RKB1 packaged gas-electric unit. The tubing carries the negative pressure signal the switch uses to confirm the inducer is running and the flue is clear before the control board allows ignition. Over time this tubing becomes brittle, cracks, kinks, or fills with condensate, which prevents the pressure switch from proving and leaves the furnace stuck in a no-heat lockout. Replacing worn tubing with this OEM-spec part restores a clean pressure signal and clears intermittent or persistent pressure-switch faults that mimic a failed switch.

Compatibility

Designed for the gas-heat section of the ICP / Tempstar / Heil / Comfortmaker WPG4364060RKB1 packaged gas-electric unit. Match the tubing diameter and routing to your original before installing.

Installation Guide

Safety First — Shut off the gas and disconnect power, then verify zero voltage with a multimeter.
Access — Remove the burner/inducer compartment service panel.
Document — Photograph the tubing routing between the inducer port and the pressure switch.
Remove — Slip the old tubing off both barbed fittings, noting any condensate or cracks.
Install — Press the new tubing fully onto the inducer port and the pressure-switch fitting, routing it so it drains and does not trap condensate.
Test — Restore gas and power, call for heat, and confirm the pressure switch proves and the burners light normally.

Frequently Asked Questions

Does this Pressure Switch fit my ICP WPG4364060RKB1 — Ships Today?

Yes. This is the factory-specified OEM pressure switch for the ICP WPG4364060RKB1 — 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 WPG4364060RKB1 — 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.
