OEM Carrier Pressure Switch for Furnace Model LC350HE400807

This genuine OEM Carrier pressure switch is a key safety control on your LC350HE400807 high-efficiency gas furnace. It monitors draft from the inducer motor and confirms the venting system is clear before allowing ignition. If it detects a blocked vent, weak inducer, condensate clog, or cracked hose, it prevents the burners from firing—protecting your home from unsafe combustion conditions. A failed or stuck pressure switch commonly causes no-ignition, furnaces that won't start, and pressure-switch fault codes. This factory-spec replacement matches the original trip point (inches of water column), port configuration, and bracket for accurate, dependable operation. Installation is moderately easy—about 20-30 minutes to swap the hose and electrical connectors and remount the switch. Always shut off power and gas, and inspect the vent and condensate lines for blockages before replacing. Restore safe, reliable startups and clear stubborn fault codes with this OEM part. Ships same-day when ordered before 3PM CST.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Furnace Model LC350HE400807?
Yes. This is the factory-specified OEM pressure switch for the Carrier Furnace Model LC350HE400807. 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 Furnace Model LC350HE400807?
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.
