Carrier LH33WZ518 Flame Sensor

Description

The Carrier LH33WZ518 is a precision OEM flame sensor designed for safe and efficient operation of gas-fired furnaces. It plays a critical role in detecting the presence of a flame and ensuring your system only remains active when combustion is stable.

Key Features

• Reliable Flame Detection: Uses ionization technology to sense flame presence and send a feedback signal to the furnace control board, reducing the risk of unsafe gas operation.
• Genuine OEM Quality: Manufactured to Carrier’s strict specifications, this sensor ensures full compatibility with many Carrier, Bryant, and Payne furnace models.
• Compact & Durable Design: Lightweight (only ~0.04 lb) with a slim profile (~3.5″ long), making it easy to install in tight control compartments.
• High Sensitivity: Rapidly detects flame presence to maintain continuous combustion, helping prevent ignition lockouts and improving system uptime.
• Long-Term Reliability: Constructed from durable materials to withstand repeated heat cycling and furnace operating conditions.
• Safety Assurance: Acts as a critical safety component — if the flame goes out unexpectedly, the sensor signals the system to shut off the gas, preventing dangerous conditions.
