OEM Carrier Low Pressure Switch 312926-258 for Model CH16NA02400GBAAA

This OEM low pressure switch (part number 312926-258) is the factory-specified replacement for the Carrier CH16NA02400GBAAA unit. The pressure switch is a critical safety component that monitors the negative pressure created by the inducer draft motor to confirm proper venting before allowing ignition to proceed. When this switch fails or detects insufficient pressure — due to a blocked flue, cracked hose, failed inducer, or a faulty switch itself — the control board locks out the ignition sequence and no heat is produced. Common symptoms include the system attempting to start, the inducer spinning, but the burners never lighting, often accompanied by a fault code indicating a pressure switch error.

  • Specs: Low pressure switch | OEM Part No. 312926-258 | Factory-calibrated W.C. (water column) rating | Designed for correct electrical continuity at proper draft pressure | Direct plug-in connector fit for Carrier CH16NA02400GBAAA
  • OEM vs Generic: This is an OEM Carrier pressure switch manufactured to exact factory W.C. ratings and tolerance specifications. Generic aftermarket switches often carry wider tolerances, risking nuisance lockouts or — more dangerously — failure to detect a true venting problem. OEM is strongly recommended for pressure switches.
  • Install difficulty: 3/5 — Turn off power and gas before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, manometer (recommended to verify draft pressure post-install). Inspect rubber hose ports for cracks and clear any condensate blockage before installing the new switch.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier CH16NA02400GBAAA. Always confirm the OEM part number 312926-258 against your unit's data plate and existing switch label before ordering. If you need fitment assistance, our HVAC parts specialists are available to verify compatibility before you purchase — same-day shipping available on all in-stock orders.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier CH16NA02400GBAAA?
Yes. This is the factory-specified OEM pressure switch for the Carrier CH16NA02400GBAAA. 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 CH16NA02400GBAAA?
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.
How fast does National HVAC Parts ship?
