Overview

This OEM pressure switch assembly with tubing (part #1178417) is the factory safety control for the ICP/Tempstar/Heil WPG4244060LKA1 gas furnace. The pressure switch confirms that the inducer (draft) motor is pulling proper combustion airflow before the control board allows the igniter and gas valve to operate. It senses negative pressure through its tubing; when adequate draft is proven, its contacts close and the ignition sequence proceeds. This switch is a critical safety interlock - if it cannot prove draft, the furnace will not fire, preventing dangerous combustion conditions. Cracked tubing, a blocked port, a weak inducer, or a failed diaphragm will keep the switch from closing and lock the furnace out.

Frequently Asked Questions

Does this Pressure Switch fit my ICP WPG4244060LKA1 - With Tubing | Ships Today?

Yes. This is the factory-specified OEM pressure switch for the ICP WPG4244060LKA1 - 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 WPG4244060LKA1 - 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.
