OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model CP48P248P210010CP

This is the factory OEM Direct Spark Ignition (DSI) control board for the Carrier CP48P248P210010CP packaged gas/electric unit. The DSI control board is the brain of the heating system — it sequences the inducer motor, manages spark ignition timing, monitors the flame sensor signal, and controls safety lockout logic. When this board fails, common symptoms include a no-heat condition, repeated ignition lockout faults, failure to energize the inducer or gas valve, or erratic burner cycling that won't resolve with a simple reset.

  • Specs: Direct Spark Ignition (DSI) control board | OEM Part Number LH33WP002 | Factory-matched for Carrier CP48P248P210010CP packaged unit | Integrated fault code diagnostics via LED indicator
  • OEM vs Generic: This is a genuine OEM Carrier board pre-programmed with the exact ignition timing, lockout thresholds, and safety sequencing specified for the CP48P248P210010CP. Aftermarket boards may use generic firmware that mismatches ignition trial timing or pressure switch polling intervals, risking nuisance lockouts or unsafe operation.
  • Install difficulty: 3/5 — Requires disconnecting 120V and 24V wiring harnesses, mounting screws, and careful photo documentation of all terminal connections before removal. Tools needed: Phillips and flathead screwdrivers, 1/4" nut driver, multimeter. Always shut off gas supply and disconnect power at the disconnect before servicing. If fault codes persist after replacement, verify inducer motor, flame sensor, and pressure switch before condemning the board.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed and factory-specified for the Carrier CP48P248P210010CP packaged gas/electric unit. Verify OEM part number LH33WP002 against your unit's data plate and existing board label before ordering. Cross-reference your model and serial number with our fitment team if you have any questions — we confirm compatibility before every order ships.

Frequently Asked Questions

Does this Control Board fit my Carrier CP48P248P210010CP?
Yes. This is the factory-specified OEM control board for the Carrier CP48P248P210010CP. 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 CP48P248P210010CP?
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?
