OEM Carrier Ignition Control Board LH33WP007 for Model PY3GNAA60115AA

This is the OEM factory-replacement ignition control board (IGC) for the Carrier PY3GNAA60115AA gas furnace. The IGC board is the central brain of your furnace's heating sequence — it manages inducer startup, hot surface ignition timing, gas valve activation, flame sensing, and safety lockout logic. When this board fails, the furnace may short-cycle, flash a fault code, lock out after an ignition attempt, or fail to produce heat entirely despite the thermostat calling for it.

• Specs: 24V control voltage | 60 Hz | Part Number LH33WP007 | Cross-references: 1068-15, 1068-83-119A, 1836V03 | Weight: 0.84 lbs
• OEM vs Generic: This is the genuine Carrier factory-authorized board, manufactured to exact OEM tolerances. Aftermarket boards may not replicate proprietary timing logic, fault code sequences, or safety lockout thresholds — risking nuisance trips or unsafe operation.
• Install Difficulty: 3/5 — Requires disconnecting 120V and 24V wiring harnesses and documenting all connector positions before removal. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, phone/camera for wiring photos, and a multimeter to verify 24V supply before installation. Always shut off gas and disconnect power at the breaker before servicing.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
