OEM Carrier Spark Electrode Ignitor LH33WZ008 for Model PY1PPA042080ACBA

This is the factory OEM spark electrode ignitor (part number LH33WZ008), the direct-fit replacement for the Carrier PY1PPA042080ACBA packaged gas unit. The ignitor is responsible for lighting the main burners every time a heat call is initiated. When the ignitor fails, the inducer motor will run, gas will be called for, but no flame will be established — causing the control board to lock out after repeated ignition attempts, leaving you with a no-heat condition. A cracked, broken, or worn electrode is one of the most common causes of furnace lockout faults in the field.
