OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY1PEB060115AAAA

This OEM Direct Spark Ignition (DSI) Control Board is the factory-specified replacement for the Carrier PY1PEB060115AAAA packaged gas/electric unit. The DSI control board is the central intelligence of your furnace or packaged system's heating section — it sequences the induced draft motor, spark ignition, gas valve, and flame sensing circuit in precise order. When it fails, common symptoms include a complete no-heat condition, repeated ignition lockouts with a flashing fault code, the burner lighting then shutting off after a few seconds, or the system failing to advance past the inducer pre-purge stage.

• Specs: Direct Spark Ignition (DSI) control | OEM Part Number: LH33WP002 | 24V control circuit | Compatible with integrated inducer, gas valve, and flame rod wiring harness on PY1PEB060115AAAA
• OEM vs Generic: This is a genuine OEM Carrier board programmed to exact factory timing parameters for ignition trial duration, inter-purge delay, and lockout retry logic. Generic aftermarket boards often use relaxed timing tolerances that can cause nuisance lockouts or incomplete combustion events — always choose OEM for a safety-critical ignition control.
• Install Difficulty: 3/5 — Requires disconnecting 120V and 24V wiring harnesses and grounding straps. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring before disconnecting. Always shut off gas and disconnect power at the disconnect box before beginning. Recommend clearing fault codes after installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
