OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY1PEA036060ADBA

This is the genuine OEM Carrier Direct Spark Ignition (DSI) Control Board, part number LH33WP002, factory-specified for the Carrier PY1PEA036060ADBA packaged unit. The DSI control board serves as the central command hub of your heating system — sequencing the ignition trial, monitoring the flame sensor signal, managing the inducer and gas valve, and triggering safety lockouts when fault conditions are detected. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockout faults, erratic cycling, or unresponsive system behavior even when thermostat calls for heat are present.

  • Specs: Direct Spark Ignition (DSI) control board | 460V application | OEM part number LH33WP002 | Replaces legacy part LH33WP002A | Factory-matched to Carrier PY-series packaged unit logic
  • OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket clone. OEM boards carry exact firmware, relay ratings, and timing sequences engineered for your unit. Aftermarket boards may use mismatched lockout timing or relay amperage, risking nuisance shutdowns or component damage.
  • Install difficulty: 4/5 — Control board replacement requires disconnecting 120V and 24V wiring harnesses, documenting all terminal positions before removal, and verifying proper grounding post-install. Recommended tools: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, phone/camera for wiring documentation. A qualified HVAC technician is strongly recommended for this repair.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY1PEA036060ADBA packaged unit. This board is also used across Carrier, Bryant, and Payne models in the 48, 574, 580, 581, 582, 583, 588, 589, and PY series — always verify your OEM part number on the existing board's label before ordering.

Frequently Asked Questions

Does this Control Board fit my Carrier PY1PEA036060ADBA?
Yes. This is the factory-specified OEM control board for the Carrier PY1PEA036060ADBA. 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 PY1PEA036060ADBA?
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?
