OEM Carrier Spark Electrode Ignitor LH33WZ008 for Model PY1PEA036100ADBA

This is the genuine OEM spark electrode ignitor (part number LH33WZ008), factory-specified for the Carrier PY1PEA036100ADBA packaged unit. The ignitor is the first critical link in your system's heating sequence — after the draft inducer proves airflow, the control board energizes the ignitor to light the main burners. When the ignitor fails or cracks, the gas valve will not open, the furnace will attempt ignition up to three times, and then lock out completely, leaving you with a no-heat call. Common symptoms include the system attempting to start but immediately locking out, a visible crack in the electrode tip, or an open circuit reading on your multimeter.

• Part Number: LH33WZ008 | Spark Electrode Ignitor | Genuine Carrier OEM replacement — no substitutions, no off-spec tolerances
• OEM vs Generic: This is a factory-authentic Carrier ignitor, not an aftermarket approximation. Generic electrodes often have inconsistent tip geometry and gap spacing, leading to misfire, repeated lockouts, and premature failure of the control board.
• Install Difficulty: 3/5 — Turn off all power and gas before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and a multimeter to verify continuity before reinstallation. Photograph all wire routing and connections before disconnecting. Handle the electrode ceramic with clean, dry gloves — skin oils can cause cracking under heat.
