Overview

This OEM pressure switch assembly with tubing (OEM part 1178417, TUBING PRESSURE SWITCH) is the direct-fit safety control for the ICP / Tempstar / Heil WPG4424060RKA1 packaged gas/electric unit. The switch proves that the inducer/draft motor is moving combustion air before the control board allows the igniter and gas valve to fire. If the switch fails open, sticks closed, or its tubing cracks or clogs, the furnace will not ignite or will lock out on a pressure fault. This listing includes the factory switch and its sensing tubing.

Frequently Asked Questions

Does this Pressure Switch fit my ICP WPG4424060RKA1 — With Tubing | Ships Today?

Yes. This is the factory-specified OEM pressure switch for the ICP WPG4424060RKA1 — With Tubing | 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 WPG4424060RKA1 — With Tubing | 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.
