OEM Carrier Ignition Control Board LH33WP007 for Model PY3GPAA42060AA

This is the genuine OEM Carrier Ignition Control Board (IGC), part number LH33WP007, factory-specified for the Carrier PY3GPAA42060AA packaged gas/electric unit. The IGC board is the central brain of your furnace or packaged system's heating sequence — it sequences the inducer motor, hot surface igniter, gas valve, and flame sensor through every call for heat. When the board fails, symptoms typically include a hard lockout with no ignition attempt, continuous lockout fault codes, burners that light and immediately shut off, or a system that simply won't respond to a heat call at all.

• Specs: 24V | 60 Hz | OEM Part # LH33WP007 | Cross-references: 1068-15, 1068-83-119A, 1836V03 | Replaces earlier revision LH33WP003A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM boards carry exact firmware timing profiles calibrated to your unit's ignition sequence. Aftermarket boards can introduce off-spec ignition delays, fault-code mismatches, and voided equipment warranties.
• Install Difficulty: 3/5 — Requires disconnecting 120V power and 24V control wiring harnesses. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone camera (photograph all wiring connections before removal). Recommend verifying fault codes with a multimeter before condemning the board.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
