OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP003 for Model PY1PNB030060AAAA

This OEM Direct Spark Ignition (DSI) control board is the factory-specified replacement for the Carrier PY1PNB030060AAAA rooftop and packaged heating unit. The LH33WP003 serves as the brain of your system's combustion cycle — sequencing spark ignition, activating the gas valve, managing the blower and indoor fan motors, and continuously monitoring the flame sensor for safe operation. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockout after failed spark attempts, blower running without heat, or the unit cycling off immediately after startup. Onboard LED diagnostic indicators make fault-code identification fast for service technicians.

  • Part Type: Direct Spark Ignition (DSI) Integrated Control Board | OEM Part# LH33WP003 | Fits Carrier PY1PNB030060AAAA packaged/rooftop gas heating units
  • OEM vs Generic: This is a genuine Carrier OEM board manufactured to original design specifications, ensuring full pin-for-pin compatibility, correct timing sequences, and preserved system safety interlock behavior. Aftermarket boards may introduce timing mismatches that cause nuisance lockouts or void equipment warranties.
  • Install Difficulty: 3/5 — Disconnect power and gas before servicing. Label all harness connectors before removal. Tools needed: ¼" and 5/16" nut drivers, needle-nose pliers, multimeter for voltage verification. Confirm all connectors are fully seated before restoring power. Recommend qualified HVAC technician for gas appliance board replacement.
  • 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 PY1PNB030060AAAA packaged rooftop gas/electric unit.

Frequently Asked Questions

Does this Control Board fit my Carrier PY1PNB030060AAAA?
Yes. This is the factory-specified OEM control board for the Carrier PY1PNB030060AAAA. 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 PY1PNB030060AAAA?
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?
