Overview

This is a genuine OEM pressure switch tubing assembly (part number 1178417) for the ICP/Tempstar/Heil WPG4304060LKA1 packaged gas unit. The tubing carries the negative pressure signal from the draft inducer assembly to the pressure switch, allowing the switch to confirm proper combustion-air venting before the ignition sequence proceeds. Cracked, collapsed, or condensate-clogged tubing is a frequent cause of nuisance pressure-switch lockouts. Symptoms include the furnace failing to light, the inducer running but ignition never starting, or a flashing control-board fault code indicating an open pressure switch.

Frequently Asked Questions

Does this Pressure Switch fit my ICP WPG4304060LKA1 — OEM | Ships Today?

How do I replace the pressure switch on my ICP WPG4304060LKA1 — OEM | Ships Today?

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.
