OEM Carrier Pressure Switch for Furnace Model GB3AAV036070AGJA

This OEM Carrier pressure switch safeguards your GB3AAV036070AGJA gas furnace by confirming the draft inducer is moving air properly before the control board allows ignition. A failed or stuck switch causes the furnace to lock out and refuse to fire, typically displaying a pressure-switch fault code and leaving your home without heat. A genuine OEM replacement is factory-calibrated to the precise trip point for this model, ensuring the burners light only when venting is clear and safe. Built to original Carrier specifications, it fits the existing bracket and sensing hose connections on the GB3AAV036070AGJA for an accurate installation. The swap is relatively easy: power down the furnace, disconnect the two terminal wires and the rubber hose, mount the new switch, and reconnect everything. Take a moment to check the hose and vent passages for condensate or obstructions, a common cause of switch trips. Orders placed before 3PM CST ship same-day, so you can restore safe, reliable furnace operation quickly with a part matched exactly to your equipment.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Furnace Model GB3AAV036070AGJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier Furnace Model GB3AAV036070AGJA. 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 GB3AAV036070AGJA?
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.
