Quick Answer
If your furnace pilot light keeps going out, start by turning the gas control knob to “Off” and waiting five minutes. Then switch it to “Pilot” and relight with a match or lighter. If it still won’t stay lit, humidity, drafts, or a worn thermocouple could be the cause—common issues in older Weirton basements near the Ohio River.
Why This Matters for Weirton Homes
From Marland Heights to the downtown flats, Weirton’s homes face unique heating challenges. River-valley moisture, fluctuating gas pressure, and concrete basements often create conditions where pilot lights struggle to stay lit. Older furnaces built before 2000 are especially prone to corrosion on the pilot assembly. Homeowners near Weir High and the North End industrial corridor often notice these problems as temperatures drop below freezing.
Typical Pilot Light Causes in Weirton
Pilot failure often comes down to one of three issues: restricted gas flow, a dirty pilot tube, or sensor malfunction. In Weirton, damp air and rust buildup inside basement furnaces frequently clog the pilot orifice, causing a weak or flickering flame. A worn thermocouple can also misread the flame temperature, shutting off gas prematurely. Homes closer to Harmon Creek or Kings Creek tend to experience more pilot instability due to basement humidity and air leaks.
Repairs and Prevention for Weirton Systems
Basic pilot repairs, such as cleaning or replacing the thermocouple, typically cost between $100 and $225 in Weirton. Gas valve repairs can reach $500–$650 for aging units. Honest Fix technicians inspect for drafts, gas flow consistency, and carbon monoxide risk during each service. To prevent relighting issues, homeowners should take the following steps:
- Seal rim joists and basement air leaks to prevent drafts.
- Install carbon monoxide detectors near sleeping areas.
- Schedule annual heating tune-ups before the first frost.
FAQs
Why does my pilot go out more often near Marland Heights?
Homes on higher ground experience more pressure fluctuations and cross-drafts. A vent cap or pressure adjustment can help stabilize the flame.
Is Weirton’s river humidity really affecting my furnace?
Yes. Moist air can corrode the pilot assembly and weaken ignition parts faster than in drier areas.
Can I safely relight the pilot myself?
Yes—if you follow your furnace’s instructions precisely and allow several minutes for gas to clear before lighting.
