FAQs
What happens when a furnace flame sensor goes bad?
When a flame sensor fails or accumulates heavy carbon buildup, it cannot properly detect the burner flame. This causes the furnace control board to shut off the gas valve shortly after ignition, resulting in the furnace turning on for a few seconds and then shutting off repeatedly.
How do I know which part number my furnace requires?
You can check your furnace user manual, inspect the existing flame sensor for stamped part numbers, or cross-reference your specific Carrier, Bryant, or Payne furnace model number with the manufacturer specifications.
Can I clean my existing flame sensor instead of replacing it?
Yes, if the sensor is simply dirty due to soot or carbon buildup, gently rubbing the metal rod with a fine emery cloth or a non-scratch scouring pad can restore its function. If cleaning does not resolve the issue, replacement is necessary.
Are these replacement parts authentic and imported from the USA?
Yes, Dropy sources these authentic Duralight replacement parts directly from the United States to ensure top-tier quality and precise compatibility for Indian homeowners maintaining imported heating systems.
Can I run my furnace without a flame sensor?
No, running a gas furnace without a functioning flame sensor is extremely dangerous. The sensor is a critical safety device designed to shut off the gas supply if no flame is present, preventing hazardous gas leaks.
