Overview

This genuine OEM tubing pressure switch (part #1178417) is the combustion safety control for the ICP/Tempstar/Heil WPG3484115LKC1 packaged unit. It is connected by tubing to the inducer/vent system and monitors negative draft pressure. Before the control board allows the igniter and gas valve to fire, the pressure switch must prove that the inducer is running and the flue path is clear. If draft is insufficient — due to a blocked vent, condensate-clogged tube, weak inducer, or the switch itself failing — the contacts won't close and the board safely halts ignition. A faulty or stuck switch is a frequent cause of no-heat lockouts and inducer-running-but-no-ignition complaints.

Access — Remove the service panel to reach the pressure switch and tubing.
Document — Photograph the wire terminals and tubing connections before disconnecting.

Frequently Asked Questions

Does this Pressure Switch fit my ICP WPG3484115LKC1 — Tubing Air Pressure Switch | Ships Today?

Yes. This is the factory-specified OEM pressure switch for the ICP WPG3484115LKC1 — Tubing Air Pressure Switch | 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 WPG3484115LKC1 — Tubing Air Pressure Switch | Ships Today?

Difficulty: Medium (20–30 min)

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.
