OEM Carrier Ignition Control Board LH33WP007 for Model PY3GNA024040AA

This is the factory OEM ignition control board (part number LH33WP007) for the Carrier PY3GNA024040AA packaged HVAC unit. The ignition control board is the brain of your system's heating sequence — it orchestrates the inducer motor, hot surface igniter, gas valve, and flame sensor in precise timed stages. When this board fails, the result is a complete loss of heat, repeated lockout codes, or a system that attempts ignition and shuts down without ever establishing a stable flame.

Specs: 24V, 60 Hz ignition control board | OEM part number LH33WP007 | Factory-direct replacement | Weight: 0.84 lbs | Compatible with Carrier 24V control circuits
OEM vs Generic: This is the genuine Carrier OEM board — not an aftermarket clone. OEM boards maintain factory-programmed timing sequences, safety lockout thresholds, and diagnostic fault codes. Aftermarket boards often lack full fault-code compatibility, leading to misdiagnosis and callbacks.
Install difficulty: 3/5 — Requires disconnecting 120V line power before servicing. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, needle-nose pliers, and a smartphone to photograph all wiring harness positions before removal. Always verify correct wiring reconnection against the unit's wiring diagram label.
Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct drop-in replacement for the Carrier PY3GNA024040AA packaged unit. Verify your existing board's part number matches LH33WP007 before ordering. Have a question about fitment? Our HVAC parts specialists confirm compatibility before you buy — call or chat today. In stock and ready to ship.

Frequently Asked Questions

Does this Control Board fit my Carrier PY3GNA024040AA?

Yes. This is the factory-specified OEM control board for the Carrier PY3GNA024040AA. 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 PY3GNA024040AA?

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.
