OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP003 for Model PY1PNA030060ADBA

This is the factory OEM Direct Spark Ignition (DSI) control board for the Carrier PY1PNA030060ADBA packaged unit. The DSI control board is the operational brain of your unit's heating system — it sequences the inducer motor, manages direct spark ignition timing, monitors flame status, and enforces safety lockouts. Common failure symptoms include a complete no-heat condition, repeated ignition lockout fault codes, intermittent heating cycles, or the unit failing to respond to thermostat calls for heat. Replacing with the exact OEM board (part number LH33WP003) ensures all timing sequences, fault detection thresholds, and safety logic match factory specifications precisely.

  • Specs: Direct Spark Ignition (DSI) control board | OEM Part Number: LH33WP003 | Factory-matched ignition timing and safety lockout logic | Compatible with 24V control circuit
  • OEM vs Generic: This is a genuine OEM Carrier board, not a generic or aftermarket substitute. OEM boards carry factory-programmed firmware and tolerance-matched components. Generic control boards frequently cause nuisance lockouts, improper ignition sequencing, and may void equipment warranties.
  • Install Difficulty: 3/5 — Requires disconnecting power and gas before beginning. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, a phone or camera to photograph all wiring harness connections before removal. We strongly recommend consulting a licensed HVAC technician for control board replacements.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model PY1PNA030060ADBA packaged units. Always cross-reference the OEM part number LH33WP003 printed on your existing board's label before ordering to confirm exact fitment. Have questions about compatibility? Our HVAC parts specialists verify fitment before every order — contact us today and we'll ship your part the same business day.

Frequently Asked Questions

Does this Control Board fit my Carrier PY1PNA030060ADBA?
Yes. This is the factory-specified OEM control board for the Carrier PY1PNA030060ADBA. 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 PY1PNA030060ADBA?
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?
