OEM Carrier Ignition Control Board 24V 60Hz for Model PY3GPAA30040NA

This OEM ignition control board (part number LH33WP007) is the factory-specified replacement for the Carrier PY3GPAA30040NA packaged unit. The ignition control board is the brain of your heating system's ignition sequence — it manages the inducer motor, hot surface igniter, gas valve, and flame sensor in precise timed stages. When this board fails, common symptoms include system lockout after ignition attempts, a no-heat condition with the inducer running but no spark or gas flow, error codes flashing on the board's LED, or the unit cycling off immediately after attempting to light.

• Specs: 24V control voltage | 60 Hz | OEM part number LH33WP007 | Factory-matched ignition timing and flame-sense circuitry
• OEM vs Generic: This is an authentic Carrier OEM board, meeting exact factory design-life testing and agency safety listings. Aftermarket boards often use lower-grade components with looser tolerances, increasing the risk of nuisance lockouts and premature failure.
• Install Difficulty: 3/5 — Disconnect all power before servicing. Label or photograph all wiring harness connections before removal. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to verify 24V control circuit integrity post-install. A qualified HVAC technician is recommended.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3GPAA30040NA packaged unit. Verify your existing board's part number against LH33WP007 before ordering.
