OEM Carrier Ignition Control Board (LH33WP007) for Model PY4GPAA60115AA

This is the OEM factory-specified ignition control board for the Carrier PY4GPAA60115AA packaged unit. The ignition control board (IGC) is the central brain of your system's heating sequence — it manages the draft inducer, hot surface igniter, gas valve, and flame sensor in a precise timed sequence. When this board fails, you'll typically experience a hard lockout with no ignition attempt, intermittent heating failures, or a system that starts briefly then shuts down due to false fault codes. Replacing this board with the correct OEM part restores factory-programmed timing and fault diagnostics.

• Specs: Part number LH33WP007 | 24V control voltage | 60 Hz | Cross-references: 1068-15, 1068-83-119A, 3618M138430, 1836V03 | Factory Authorized Parts designation
• OEM vs Generic: OEM boards retain exact factory-programmed ignition timing, safety lockout sequences, and diagnostic LED codes. Generic aftermarket boards frequently use non-matched firmware that can trigger nuisance lockouts or mask real safety faults — not a risk worth taking on a gas appliance.
• Install difficulty: 3/5 — Requires disconnecting low-voltage and line-voltage wiring harnesses. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone camera (photograph all wiring before disconnecting). Always shut off gas supply and cut power at the disconnect before servicing. Confirm system powers up correctly and cycles through a full heat sequence before closing the unit.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
