OEM Carrier Pressure Switch HK06WC078 for Model GA2AAD036091ACJA

This genuine OEM Carrier pressure switch (HK06WC078) is a critical safety device on your Carrier GA2AAD036091ACJA gas furnace, confirming that the inducer motor is producing proper draft before the control board allows ignition. A failed or stuck pressure switch is a leading cause of furnaces that won't fire, lock out on startup, or flash a pressure-switch fault code. Replacing it with the exact factory-spec switch ensures the correct pressure setpoint (in. w.c.) and hose-port configuration for safe, reliable operation. This is an easy DIY repair for most homeowners; expect 15 to 30 minutes. Shut off power and gas, transfer the rubber hose to the new switch, and reconnect the two spade terminals. Using OEM guarantees the proper trip rating calibrated for the GA2AAD036091ACJA, preventing dangerous false starts or nuisance lockouts. In stock and ready to go. Order before 3PM CST and it ships the same day so you can restore safe heating fast. Backed by our fit guarantee and trusted by HVAC technicians nationwide for dependable Carrier safety components.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model GA2AAD036091ACJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model GA2AAD036091ACJA. 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 GA2AAD036091ACJA?
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.
