FAQs
What are the most common signs of a blown ignitor in my furnace or heat pump?
Typical symptoms include repeated clicking without ignition, the furnace cycling on and off quickly, a sudden lack of warm air even though the blower is running, or seeing an error code flashing on your thermostat or control board. In many Maynardville homes, a tripped breaker or unusually high electric bill can also point to an ignitor that is constantly trying—and failing—to light the burner.
Why do ignitors fail so often in the Maynardville area?
Ignitors are exposed to repeated heating and cooling cycles, which cause the ceramic surface to crack over time. In Maynardville, hard-water minerals, dust from seasonal pollen, and higher humidity can accelerate corrosion or leave residue on the ignitor surface. Power surges from summer thunderstorms and aging wiring in older homes also put extra stress on the component, shortening its lifespan.
Is it safe to replace a blown ignitor myself, or should I call a professional?
While a handy homeowner can often locate the ignitor, replacement is best left to an HVAC technician. A wrong part number, improper handling of the fragile ceramic, or misaligned mounting can lead to gas leaks, cracked heat exchangers, or voided equipment warranties. Our certified technicians follow manufacturer torque specs and perform safety checks—such as verifying flame sensor readings—before leaving your Maynardville home.
How long does an ignitor replacement or heat repair visit usually take?
Most blown ignitor repairs can be completed in 60–90 minutes. The technician starts by confirming the failure with a multimeter, cleans the burner assembly, installs the new OEM-rated ignitor, calibrates the gas pressure, and runs a full heating cycle. If the service truck has the appropriate part in stock—something we plan for by tracking common models in Maynardville—your heat can be restored the same day.
What does it typically cost to repair or replace a furnace ignitor in Maynardville?
Prices vary by furnace model and part availability, but most homeowners spend between $180 and $350, which includes the diagnostic fee, OEM ignitor, labor, and post-installation safety testing. We provide upfront flat-rate pricing before any work begins and always offer a written warranty on both parts and labor.
How can I prevent future ignitor failures and keep my heating system running efficiently?
Schedule a fall tune-up to have the burner compartment vacuumed and electrical connections tightened. Replace or clean air filters every 30–60 days to reduce dust buildup on the ignitor. Consider installing a whole-home surge protector to shield sensitive components from electrical spikes common during East Tennessee storms. Keeping the area around your furnace free of lint and pet hair will also ensure adequate airflow and prolong ignitor life.
