Pilot Light Won't Stay Lit In Columbus? Here's Why
Is your gas water heater pilot light in Columbus, OH not staying lit? We cover the three main reasons: thermocouple issues, gas valve failure, or venting.
Three likely culprits, in order
When your gas water heater pilot keeps extinguishing, it's almost always due to one of three issues: a faulty thermocouple, a malfunctioning gas valve, or a downdraft in the venting system. Here’s how to identify the problem.
Cause 1: Thermocouple (most common)
The thermocouple is a small copper sensor positioned in the pilot flame. When heated, it produces a tiny electrical signal that signals the gas valve to maintain gas flow. If it fails, the valve immediately cuts off gas when you release the button. A new thermocouple is an inexpensive part, typically under $25. Labor in Columbus usually ranges from $175 to $275.
Cause 2: Gas valve
If the thermocouple checks out but the pilot still won't stay lit, the gas valve itself has probably failed. This is more common in water heaters that are eight years old or older. Replacing the valve, including labor, typically costs $450 to $650 in most Columbus homes, from Clintonville to Dublin.
Cause 3: Downdraft or vent problem
Older homes in neighborhoods like German Village, Olde Towne East, or Victorian Village can sometimes experience downdrafts that blow out the pilot, especially on blustery days. Inspect your venting system. If it's loose, improperly sized, or shares a flue with a furnace that isn't drafting correctly, the pilot will repeatedly go out. This situation requires a professional for vent repairs.
