OEM Carrier Ignition Control Board LH33WP007 for Model PY4GPAB36060NA

This OEM ignition control board (part# LH33WP007) is the factory-specified replacement for the Carrier PY4GPAB36060NA packaged HVAC unit. The ignition control board serves as the operational brain of your heating system — sequencing the inducer motor, hot surface igniter, gas valve, and flame sensor through every call for heat. When this board fails, symptoms typically include a complete no-heat condition, repeated ignition lockout faults, erratic furnace cycling, or error codes indicating ignition or flame-sensing failures that won't clear with a reset.
