OEM Carrier Pressure Switch HK06WC089 for Model LC348TM402290 Furnace

This OEM Carrier pressure switch (part HK06WC089) verifies proper draft and venting before your Carrier LC348TM402290 furnace allows ignition. It senses negative pressure created by the inducer motor and closes its contacts to prove the flue is clear and the vent is unobstructed. A failed or stuck pressure switch is a leading cause of no-heat lockouts, inducer running with no ignition, and error codes pointing to a blocked vent. Replacing it restores safe, code-compliant sequencing on startup. Built to exact Carrier specifications, this switch matches the correct trip point, port configuration, and mounting for the LC348TM402290, ensuring accurate pressure sensing. Installation is straightforward — about 20 minutes: cut power, mark and disconnect the hose and wires, remove two screws, and mount the new switch. A confident DIYer can handle it; technicians will find it routine. Genuine OEM construction means reliable performance and safety. In stock now and ships same-day on orders placed before 3PM CST so your heat is back fast.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model LC348TM402290 Furnace?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model LC348TM402290 Furnace. 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 Carrier Model LC348TM402290 Furnace?
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 Carrier 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 Carrier 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.
