OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY1PEB048115AAAA

This is the genuine OEM Carrier Direct Spark Ignition (DSI) control board, part number LH33WP002, factory-specified for the Carrier PY1PEB048115AAAA packaged unit. The DSI control board serves as the central command module for the heating system — it sequences the inducer motor, manages spark ignition timing, monitors flame sensing feedback, and executes safety shutdowns when fault conditions are detected. When this board fails, common symptoms include a hard lockout with no ignition attempt, intermittent no-heat calls, the unit sparking continuously without establishing flame, or error codes indicating an ignition control fault.

  • Part Specs: OEM part number LH33WP002 | Direct Spark Ignition (DSI) control board | 460V ignition control module | Factory-matched for Carrier PY1PEB048115AAAA packaged HVAC equipment | Weight: 0.66 lbs
  • OEM vs Generic: This is a genuine Carrier OEM board — not a third-party clone. OEM boards carry factory firmware and tolerance-matched components, ensuring proper ignition sequencing, safety lockout timing, and flame signal thresholds. Aftermarket boards frequently cause nuisance lockouts or unsafe ignition delays due to firmware mismatches.
  • Install Difficulty: 3/5 — Requires disconnecting 24V and line-voltage connectors, photographing all wiring harness positions before removal, and verifying DIP switch or jumper settings match the original board. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Always cut power at the disconnect before servicing. Recommend licensed HVAC technician for packaged unit board replacement.
  • Warranty & Shipping: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY1PEB048115AAAA packaged unit. Verify your existing board's part number against LH33WP002 or its updated revision LH33WP002A before ordering. If you need fitment confirmation, our parts team will verify compatibility before your order ships — just reach out before checkout.

Frequently Asked Questions

Does this Control Board fit my Carrier PY1PEB048115AAAA?
Yes. This is the factory-specified OEM control board for the Carrier PY1PEB048115AAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier PY1PEB048115AAAA?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
How fast does National HVAC Parts ship?
