CARRIER BRYANT PAYNE Furnace Flame Sensor LH680534

Ensure your Carrier, Bryant, Payne, or Day & Night gas furnace runs safely and efficiently with the genuine Carrier LH680534 Flame Sensor. This OEM direct-fit replacement part (also compatible with LH680012, LH680014, LH33WZ511, LH33WZ515, LH33WZ517, and obsolete LH33WZ521) restores proper flame detection to prevent common issues like short cycling, no heat, or unsafe gas release.

Key Features

  • OEM Precision Fit: Factory-authorized design for exact match and seamless installation in compatible Carrier HVAC systems.
  • Durable Construction: High-grade Kanthal flame rod withstands extreme temperatures (up to 1800°F+) and thermal cycling in the combustion chamber.
  • L-Shaped/Bent Design: Optimized geometry (approximately 73° bend) for proper positioning in the burner flame.
  • Reliable Microamp Signal: Quickly detects flame presence to confirm safe ignition and keep the gas valve open only when needed.
  • Easy Installation: Includes lead wire; typically a straightforward DIY or professional swap.

Benefits

  • Enhanced Safety: Prevents dangerous gas buildup by ensuring the furnace only operates with a confirmed flame.
  • Restores Reliable Heating: Eliminates short cycling (furnace lights then shuts off after a few seconds), no-heat conditions, and frequent lockouts caused by faulty sensors.
  • Cost-Effective Fix: Far more affordable than full service calls; often solves the most common furnace failure point quickly.
  • Long-Lasting Performance: High-quality materials resist soot, corrosion, and wear for dependable winters ahead.
  • Peace of Mind: Genuine Carrier part guarantees compatibility and performance, minimizing risks of mismatches or system inefficiencies.

This high-quality flame sensor is the trusted choice for homeowners and technicians looking to quickly restore furnace reliability and safety. Perfect for preventive maintenance or emergency repairs.
