OEM Carrier Ignition Control Board LH33WP007 for Model PY3GPAA48115NA

This is the factory OEM ignition control board (IGC board) for the Carrier PY3GPAA48115NA packaged gas/electric unit. The ignition control board is the brain of the heating sequence — it manages the inducer motor, hot surface igniter, gas valve, and flame sensor in a precise timed cycle. When this board fails, the system may enter a hard lockout, fail to initiate the ignition sequence, short-cycle, or display a fault code indicating a control board error. Replacing it with the correct OEM part restores factory-programmed timing and safeguard logic.

• Specs: OEM Part Number LH33WP007 | 24V control voltage | 60 Hz | Cross-references: 1068-15, 1068-83-119A, 3618M138430 | Weight: 0.84 lbs
• OEM vs Generic: This is the genuine Carrier Factory Authorized Part. Generic or aftermarket boards often use approximated firmware timing, which can cause nuisance lockouts, improper fault codes, and voided equipment warranties. OEM is always the recommended choice for packaged units in commercial or light-commercial applications.
• Install Difficulty: 3/5 — Disconnect power at the unit disconnect and verify zero voltage before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, smartphone to photograph all wiring harness connections before removal. Reconnect harnesses in reverse order. Re-enable power and run a full heating cycle to confirm proper ignition sequence.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
