Why does my gas burner keep going out?

Why does my gas burner keep going out?

The most common cause of this is dirty or blocked burners, which is the part that you can easily take off to clean. All the small holes on the burner should be clean and clear, if not then even a partial blockage can lead to the thermocouple not getting enough heat and, the burner won’t stay lit.

How do I know if my thermocouple is bad?

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. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that’s the sign of a thermocouple malfunction.

How often do thermocouples need to be replaced?

Thermocouples can last several years, but they don’t typically last as long as the furnace itself. If the pilot remains lit, but the main furnace doesn’t stay lit, it’s time to replace the thermocouple. Replacement thermocouples are in stock at most hardware and home improvement stores.

Can you fix a thermocouple?

When a thermocouple fails, the pilot light won’t stay lighted. A burned out or broken thermocouple should be replaced. To replace a thermocouple: Step 1: Unscrew the copper lead and the connection nut inside the threaded connection to the gas line.

What causes a thermocouple to fail?

Changes in temperature can cause regular expansion and contraction in metal, which will cause thermocouples to weaken over time. After enough time, metal fatigue can cause a thermocouple to break. If thermocouples start to give out unusual readings, it may be suffering from metal fatigue.

Will the pilot light stay lit if the thermocouple is bad?

When the pilot goes out, this component send a signal to the gas valve to make sure that it remains closed while the pilot light is not yet lit. This means that if the thermocouple goes bad, there is no way of detecting if the pilot light is burning or not.

Why does the pilot keep going out?

Usually, a problem with the thermocouple causes the pilot light to go out. The thermocouple is the small copper rod that the pilot light hits. The thermocouple’s job is to shut a gas safety valve if the pilot light goes out. That’s important because gas is always being supplied to the pilot to keep the flame lit.

Should the pilot light always be on in a gas fireplace?

Electronic ignition is when the pilot light on a gas fireplace/insert/stove is only running when the fireplace is on, this means that the unit is likely to have a battery backup as well. A standing pilot is always on, always using a small amount of gas to run constantly unless the gas is physically turned off.
