Not enough combustible air. If your water heater is located in a utility closet or anywhere it is starved for combustible air, the pilot light may go out. This situation could also lead to a build-up of Carbon Monoxide, which can be life threatening.
Thereof, What would cause the pilot light to go out on a water heater?
Some of the most common reasons that water heater pilot lights go out include: A faulty thermocouple. … Over time, thermocouples can begin to malfunction and shut off the gas supply to the pilot light even if it’s burning properly. A bent or dirty thermocouple.
Also to know is, How do you know if you have a bad thermocouple? If you can’t get the flame to light at all, and you’re sure the gas is on, there’s probably an obstruction in the pilot tube.

What causes a thermocouple to go bad?
It’s Dirty. Soot buildup on the thermocouple may block the flame. Under constant exposure to a hot flame, a thermocouple wears down over time. Even a slight residue can make the thermocouple malfunction.
Can you get carbon monoxide poisoning from a pilot light?
Carbon monoxide is only produced when fuel of any type; oil, gas, wood or coal is burned. … And a pilot light out of adjustment can produce carbon monoxide gas. The amount produced by even a badly maladjusted pilot is small because the flame size is also small.
How much does it cost to replace a thermocouple on a water heater?
The thermocouple is an apparatus that senses whether the pilot light is lit and triggers the gas control valve. Repairs typically cost about $150 to have it done professionally, though a new thermocouple itself only costs about $20 on average.
How long should a thermocouple last?
How much carbon monoxide does a pilot light produce?
Also, a typical pilot light can generate 450 pounds of carbon dioxide – a greenhouse gas — over a six-month period.
Can you get carbon monoxide poisoning from a gas stove?
Carbon Monoxide Poisoning: Gas-fired Kitchen Ranges (AEN-205) Gas kitchen ranges releasing unvented combustion products into the kitchen are common in many homes. Studies show carbon monoxide concentrations in the kitchen are elevated when the stove is used without using the range hood.
How much should I charge to replace a water heater?
between $1,000 to $3,000
Is the pilot light supposed to stay on in a water heater?
