OEM Carrier Low Pressure Switch 312926-258 for Model CH16NA03600GABAA

This OEM low pressure switch (part number 312926-258) is the factory-specified replacement for the Carrier CH16NA03600GABAA condensing unit. The pressure switch is a critical safety component that monitors negative air pressure created by the inducer motor to confirm proper venting before allowing ignition to proceed. When the switch fails or becomes stuck open, the control board cannot verify safe venting conditions — resulting in a no-heat lockout, fault codes, or a system that attempts ignition and immediately shuts down without ever firing the burners.

  • Specs: Low pressure switch | OEM part number 312926-258 | Factory-calibrated W.C. (water column) rating | Single-port hose connection | 1/4" Faston terminals | Designed for Carrier CH16NA03600GABAA
  • OEM vs Generic: This is an authentic OEM Carrier pressure switch calibrated to the exact water-column rating required by your unit. Aftermarket switches frequently carry imprecise trip points that cause nuisance lockouts or — more dangerously — allow ignition under unsafe venting conditions.
  • Install difficulty: 2/5 — Shut off power at the breaker and gas supply before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Disconnect the rubber hose and two wiring terminals, swap the switch, and reconnect. Always inspect the hose for cracks or blockages while the switch is removed.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Carrier CH16NA03600GABAA condensing unit. Verify the OEM part number 312926-258 on your existing switch or unit wiring diagram before ordering to confirm fitment. Our HVAC parts specialists are available to verify compatibility prior to purchase. Order today and receive same-day shipping on all in-stock components.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier CH16NA03600GABAA?
Yes. This is the factory-specified OEM pressure switch for the Carrier CH16NA03600GABAA. 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 CH16NA03600GABAA?
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?
