OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP003 for Model PY2PPB030060AA

This is the genuine OEM Direct Spark Ignition (DSI) control board for the Carrier PY2PPB030060AA packaged rooftop unit. As the brain of your heating system, this integrated ignition control board manages the entire combustion sequence — from initiating spark and opening the gas valve, to controlling blower and indoor fan motors, monitoring flame sensing, and executing safety lockout when a fault is detected. When this board fails, common symptoms include no-heat calls, ignition lockout after a trial period, erratic blower behavior, or a system that starts briefly then shuts down. Fault LED codes on the board itself can help pinpoint the failure before replacement.

  • Specs: Direct Spark Ignition (DSI) microprocessor-based control | OEM Part# LH33WP003 | Carrier / Bryant compatible | Integrated ignition, gas valve, blower, and fan motor sequencing | Onboard LED status/fault code indicators for fast diagnostics
  • OEM vs Generic: This is the factory-authorized OEM board engineered to Carrier's original design specifications, ensuring full compatibility and preserving system integrity. Aftermarket boards may lack proper timing calibration, increasing the risk of nuisance lockouts or premature failure.
  • Install difficulty: 3/5 — Disconnect power and confirm 0V at the board before handling. Tools needed: nut driver set, needle-nose pliers, multimeter, phone/camera to photograph all wire connections before removal. Label every connector. Always verify gas valve wiring polarity before restoring power.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for the Carrier PY2PPB030060AA packaged rooftop unit with Direct Spark Ignition. Verify your existing board's part number (LH33WP003 or LH33WP003A) against your unit's data plate before ordering. Need a fitment confirmation?

Frequently Asked Questions

Does this Control Board fit my Carrier PY2PPB030060AA?
Yes. This is the factory-specified OEM control board for the Carrier PY2PPB030060AA. 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 PY2PPB030060AA?
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?
