OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY2PEB060115AB

This is the genuine OEM Direct Spark Ignition (DSI) Control Board for the Carrier PY2PEB060115AB packaged gas/electric unit. As the central command module of the heating system, this board manages the complete ignition sequence — energizing the inducer motor, monitoring pressure switches, firing the igniter, proving flame via the flame sensor, and staging the gas valve. When this board fails, symptoms typically include repeated ignition lockouts, a system that attempts to light but immediately shuts down, error codes on the thermostat, or a furnace that produces no heat at all despite the blower running normally.

• OEM Part Number: LH33WP002 (also superseded by LH33WP002A) | Manufacturer: Carrier | Application: Direct Spark Ignition (DSI) Control | 460V ignition control module
• OEM vs Generic: This is a factory-original Carrier board with pre-programmed ignition timing, lockout thresholds, and fault logic matched exactly to the PY2PEB060115AB. Aftermarket boards frequently misalign timing sequences, causing nuisance lockouts or premature heat exchanger stress — always choose OEM for control boards.
• Install Difficulty: 3/5 — Disconnect power at the breaker and verify zero voltage before touching any terminals. Document all wiring connections with photos before removal. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, smartphone for wiring photos. Note: some boards require a short calibration cycle on first power-up.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse when ordered before cutoff.
