OEM Carrier Ignition Control Board 24V 60Hz for Model PY3GNA060115NA

This OEM ignition control board (part number LH33WP007) is the factory-specified replacement for the Carrier PY3GNA060115NA gas furnace. The integrated furnace control (IFC) board is the brain of your heating system — it sequences every stage of the heating cycle, from inducer startup and pressure switch verification to hot surface ignition, flame sensing, and blower operation. When the board fails, symptoms typically include a hard lockout with no ignition attempt, intermittent no-heat calls, or fault codes indicating a control board failure on your thermostat or diagnostic LED display.

• Specs: 24V control voltage | 60Hz | OEM part number LH33WP007 | Factory-matched timing and sequencing parameters for the PY3GNA060115NA platform
• OEM vs Generic: This is the genuine Carrier OEM board — not an aftermarket substitute. OEM boards retain factory-programmed timing sequences, fault-code logic, and safety lockout thresholds. Generic boards can introduce mismatched timing that leads to nuisance lockouts or, worse, unsafe combustion sequences.
• Install Difficulty: 4/5 — Control board replacement requires shutting off gas and 120V power, photographing all wiring harness connections before removal, and carefully transferring each connector to the new board. A multimeter is recommended to verify 24V to the board before assuming board failure. Always clear fault history after installation.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
