Pilot Light & Ignition Repair in Nashville
A furnace that will not light or shuts down shortly after ignition needs the cause checked before a component is replaced. Harpeth Air provides furnace ignition and pilot light service in Nashville and Middle Tennessee. Share the model, symptoms, and any displayed fault code when you call.
Smell gas? Leave immediately. From a safe location, call 911 and your gas utility emergency line. Do not operate switches or try to relight the furnace. Read Atmos Energy gas-leak guidance. If a CO alarm sounds, move outside to fresh air and call 911; see CPSC carbon monoxide guidance.
Standing Pilots and Electronic Ignition
Older furnaces may use a standing pilot, while other systems use a hot-surface igniter or electronic spark ignition. The operating sequence and compatible replacement parts depend on the furnace model. An ignition failure can also involve the fuel supply, draft system, controls, or safety devices rather than the igniter itself.
The Furnace Lights, Then Shuts Off
A brief flame followed by shutdown can indicate a flame-sensing or other control problem. Repeated attempts to start can also result from airflow or venting conditions that trigger a safety control. Note what the furnace does without removing covers or bypassing switches. A technician can assess the sequence and determine which tests or repairs are appropriate.
Gas Odor Requires Immediate Action
If you smell gas or suspect a leak, leave the area immediately and tell others to leave. Avoid operating switches, using a phone in the affected area, or attempting to relight or repair the appliance. From a safe location, call 911 and your gas utility emergency line. Follow their instructions and wait for clearance before returning.
Arranging Ignition Service
If there is no suspected gas leak or other emergency, call with your location, furnace information, and symptoms. Do not repeatedly reset a furnace that will not stay on. Ask about diagnostic charges and the next available appointment. The repair plan depends on the diagnosis and compatible parts; completion may require a return visit.

Frequently Asked Questions
Is a dirty flame sensor always the cause of a furnace shutting off?
No. Flame sensing is one possibility, but ignition, airflow, venting, and other controls can produce similar symptoms. A diagnosis should establish the cause rather than assume that cleaning one part will resolve it.
How much does furnace igniter replacement cost?
The compatible part, diagnosis, access, and labor affect the quote. Ask about the diagnostic charge and review the proposed repair before approving work.
Should I relight a pilot that keeps going out?
Repeated pilot failure needs professional assessment. Do not keep attempting to relight it or bypass a safety device. If there is a gas odor, leave immediately and call 911 and your gas utility from a safe location before requesting ordinary service.
