OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model CP48P248P206011CP

This is the OEM factory-specified Direct Spark Ignition (DSI) control board for the Carrier CP48P248P206011CP packaged gas/electric unit. The DSI control board serves as the brain of the heating system, managing the ignition sequence, gas valve timing, inducer motor operation, flame verification, and safety lockout logic. When this board fails, common symptoms include a no-heat condition, repeated ignition lockout faults, erratic burner cycling, or a system that sparks but never establishes a sustained flame.

  • Specs: OEM Part Number LH33WP002 | Direct Spark Ignition (DSI) control board | Factory-programmed ignition timing and retry/lockout logic | 24V control circuit compatible | Designed for Carrier packaged unit application
  • OEM vs Generic: This OEM board is factory-programmed with the exact ignition timing, retry sequences, and safety lockout parameters required by the CP48P248P206011CP. Aftermarket boards often use generalized firmware that can cause nuisance lockouts, improper gas valve timing, or voided equipment warranties — risks not worth taking on a gas-fired appliance.
  • Install Difficulty: 3/5 — Requires disconnecting 24V and line-voltage wiring harnesses, documenting all connector positions before removal, and verifying proper grounding post-install. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, phone camera for wiring documentation. Always shut off gas supply and disconnect power at the disconnect box before beginning. Verify all safety switch inputs after installation.
  • Warranty: 1-year OEM manufacturer warranty against defects. Leaves our warehouse the same business day the order is placed.

Compatibility: This board is engineered specifically for the Carrier CP48P248P206011CP packaged unit. Confirm OEM part number LH33WP002 against your unit's wiring diagram or data plate before ordering. If you are unsure of fitment, our HVAC parts specialists are available to verify compatibility before you purchase — ensuring you get the right board the first time. Order now and ship today from our stocked warehouse.

Frequently Asked Questions

Does this Control Board fit my Carrier CP48P248P206011CP?
Yes. This is the factory-specified OEM control board for the Carrier CP48P248P206011CP. 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 CP48P248P206011CP?
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?
