Carrier LH33WZ015 Flame Sensor for Gas Furnaces

The Carrier LH33WZ015 is a genuine OEM flame sensor designed for use in residential and light commercial gas furnaces. This critical safety component detects the presence of a flame during furnace operation, ensuring proper and safe heating system performance.

Key Features:

• Detects flame presence in hot surface ignition systems to confirm successful burner ignition
• Signals control board to shut off gas valve if no flame is detected, preventing dangerous gas accumulation
• High-temperature flame rod design withstands extreme heat exposure
• Quality ceramic insulator provides electrical isolation and durability
• Genuine Carrier OEM part ensures proper fit and reliable operation

The flame sensor works by detecting the electrical current generated when a flame is present. If the sensor fails to detect a flame or becomes fouled with carbon deposits, the furnace control system will prevent the gas valve from opening or will shut it down as a safety measure. This part is compatible with numerous Carrier 48HGD and 48HGE series furnace models. Regular inspection and cleaning of the flame sensor is recommended to maintain optimal furnace performance and prevent nuisance shutdowns.
