OEM Carrier Pressure Switch for Model FIOP100F311GA - In Stock

This OEM Carrier pressure switch is a genuine replacement designed for the FIOP100F311GA gas furnace. The pressure switch monitors draft and venting safety, confirming proper airflow through the inducer before the control board allows ignition. When the switch fails, your furnace may short-cycle, lock out, or refuse to fire entirely. Built to exact factory specifications, this part guarantees correct pressure calibration and reliable safety operation, matching the OEM trip point and electrical ratings for the FIOP100F311GA. Installation is moderate and well within reach of most experienced DIYers: shut off power and gas, disconnect the two vinyl hoses and spade terminals, swap the switch, and reconnect. Always verify ratings against your unit's rating plate before installing. Using a genuine Carrier pressure switch protects your furnace warranty and ensures dependable cold-weather heating performance. In stock and ready to ship.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model FIOP100F311GA - In Stock?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model FIOP100F311GA - In Stock. 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 FIOP100F311GA - In Stock?

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.
