OEM Carrier Spark Electrode Ignitor LH33WZ008 for Model PY1PEA042120ACBA

This OEM spark electrode ignitor (part number LH33WZ008) is the factory-specified replacement for the Carrier PY1PEA042120ACBA packaged gas/electric unit. The ignitor is the first critical component in the furnace ignition sequence: after the draft inducer proves airflow, the control board energizes the ignitor to generate the spark or glow needed to ignite the main burners. When this part fails, the furnace will attempt ignition up to three times and then lock out entirely, leaving you with no heat. Common symptoms include repeated ignition attempts with no flame, visible cracking or carbon tracking on the electrode, or a fault code indicating ignition failure on the control board.

• Part Number: LH33WZ008 | OEM Carrier Spark Electrode Ignitor | Genuine factory part — not an aftermarket substitute
• OEM vs Generic: This is a true OEM Carrier part, manufactured to exact factory tolerances for electrode gap, ceramic insulator rating, and wire lead length. Generic electrodes often suffer from mismatched gap spacing and inferior ceramic, leading to premature cracking and repeat failures within one heating season.
• Install Difficulty: 2/5 — Straightforward replacement. Turn off power and gas before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Handle the ceramic insulator with care — avoid contact with skin oils, which can cause premature cracking under heat cycles. Photograph wiring orientation before disconnecting.
