Flame Sensors Replacements for Furnaces

Flame sensor parts are essential components in furnaces and HVAC systems, designed to detect the presence of a flame and ensure safe combustion operation. Furnace flame sensors ensure accurate flame detection to prevent unsafe conditions and unexpected system shutdowns. They are used to monitor the presence of a flame, verify proper combustion, and trigger the furnace to shut down if a problem is detected.

By monitoring combustion, these flame sensors help regulate furnace operation, promoting efficient heating, energy savings, and consistent performance. Signs of a failing flame sensor include frequent lockouts, uneven heating, or unexpected system interruptions.

FAQs

How do I know if my flame sensor is failing?

Signs of a failing flame sensor include frequent furnace lockouts, uneven heating, delayed ignition, or unexpected system shutdowns.

Can I clean a flame sensor instead of replacing it?

Yes, flame sensors can often be cleaned with fine sandpaper or a flame sensor cleaner to remove soot or debris, but replacement is recommended if cleaning doesn’t restore proper operation.

How long do flame sensors typically last?

With proper maintenance, flame sensors can last 8–12 years, but lifespan may vary depending on furnace usage, environment, and quality of the sensor.

How do I replace a furnace flame sensor?

Turn off power to the furnace, remove the old sensor, install a new flame sensor or rod kit, and reconnect wiring to restore safe furnace operation.

Why is my flame sensor causing frequent furnace lockouts?

Frequent lockouts are usually caused by a dirty, misaligned, or failing flame sensor. Cleaning or replacing the sensor often resolves the issue.
