OEM Carrier Ignition Control Board LH33WP007 for Model PY4GPAA48090AA

This OEM ignition control board (IGC) is the factory-specified replacement for the Carrier PY4GPAA48090AA packaged gas/electric unit. The IGC board is the central brain of your system's heating sequence — it manages the inducer motor, hot surface igniter, gas valve, and flame sensor in a precise timed cycle. When this board fails, you'll typically experience symptoms such as a complete no-heat condition, repeated ignition lockouts, erratic cycling, or error codes flashing on the board's diagnostic LED. Replacing it with the correct OEM part ensures factory-matched timing and full compatibility with all onboard safeties.

  • Specs: OEM Part Number LH33WP007 | 24V, 60 Hz control circuit | IGC (Integrated Gas Control) board | Also cross-references: 1068-15, 1068-83-119A, 3618M138430 | Weight: 0.84 lbs
  • OEM vs Generic: This is the genuine Carrier Factory Authorized Part. OEM boards carry exact firmware, relay ratings, and terminal layouts matched to your unit.

Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, phone or camera to photograph all wiring harness connections before removal. Transfer wiring connector by connector. Restore power and run a full heat cycle to confirm all stages operate correctly.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct OEM replacement for the Carrier PY4GPAA48090AA packaged gas/electric unit. Cross-references include board numbers 1068-15 and 1068-83-119A.

How do I replace the control board on my Carrier OEM Carrier Ignition Control Board LH33WP007 — PY4GPAA48090AA?
Difficulty: Advanced (1–2 hrs)

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.
