Carrier LH33WZ006 Ignitor Sensor

As a seasoned technician, you know that a reliable Carrier LH33WZ006 Ignitor Sensor is the backbone of safe combustion in gas-fired systems. This OEM Carrier furnace flame sensor is a high-precision component engineered to detect the presence of a flame during the ignition sequence. If the furnace ignitor and sensor fail to send a millivolt signal to the HVAC control board, the system will immediately initiate a safety lockout to prevent hazardous gas accumulation. Built with specialized high-temperature resistant materials, the LH33WZ006 is designed to withstand the intense thermal cycling of commercial and industrial burners. Whether you are performing a Carrier ignition system repair or a routine maintenance swap, this direct-fit sensor ensures the HVAC flame rectification process remains steady and accurate. This authentic Carrier factory authorized part eliminates the guesswork involved with generic alternatives, providing the exact impedance and mounting alignment required for Carrier, Bryant, and Payne gas furnaces.

• Precise Flame Detection: Immediate signal feedback to the control module prevents gas build-up and ensures reliable ignition cycles.
• OEM Compatibility: Exact replacement for LH33WZ006, ensuring perfect fitment in Carrier gas-fired appliances without modification.
• Enhanced Durability: Constructed with industrial-grade materials to resist oxidation and carbon buildup in the burner assembly.
• Safety Compliance: Crucial for maintaining UL-recognized safety sequences within the combustion chamber.

• How do I know if the flame sensor is failing? If the furnace ignites but shuts down after a few seconds (short cycling), the sensor may be dirty or defective, failing to verify the flame.
• Can this sensor be cleaned? While light oxidation can sometimes be removed with a fine abrasive pad, a cracked ceramic insulator or deep pitting requires a full replacement of the LH33WZ006.
• Is this a universal part? No, this is an OEM Carrier replacement. To ensure proper flame rectification, always match the part number to your specific furnace model's technical literature.
