Why does my gas fireplace turn off after a few minutes?
If you get dust in the pilot assembly and the pilot needs to be cleaned out, it produces a “lazy” flame, which will be disturbed by the draught of the main burners. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. This, in turn, makes the gas valve shut off.
Why does my ventless fireplace keep going out?
A common problem with gas fireplaces lies in the components called the ignition assembly. When a fireplace refuses to remain lit, there’s probably an issue in one of the several pieces that make up the ignition assembly, which are: the pilot light assembly, pilot tubing, thermocouple, and thermopile.
Why does gas fireplace go off and on?
Bad Thermo Couple or Thermo Pile A thermo couple is a sensor device that detects heat and permits the pilot light to stay lit. One of these devices could have gone bad or may have shorted out, causing your fireplace to turn shut down or turn back on at random.
Is it dangerous if fireplace pilot light goes out?
Can a Pilot Light Outage Be Dangerous? The worry here is that when a pilot goes out, the gas valve that supplies the fuel for the pilot flame could still be pumping gas. This can mean a buildup of gas, and when the pilot is relit or relights itself it could result in a very serious explosion.
Should pilot light always be on fireplace?
Save Energy and Money We recommend that you turn off your gas fireplace pilot light seasonally. Turning off your gas fireplace’s pilot light can save a substantial amount of energy and money. It is important to remember that not all gas fireplaces have “standing” pilot light, or, a pilot light that is “always on”.
Do I need to turn gas off if pilot light goes out?
It should be turned off, and must be turned off to allow the pilot to be relighted, but there is a safety feature in gas appliances that if the pilot light goes out, a heat operated valve cools off and shuts the gas supply to the pilot light and the main burner.
What do you do when the pilot light goes out on your fireplace?
How to Relight a Pilot Light
- Turn off your appliance at the power switch or thermostat.
- Find the gas valve control knob and turn it to select “pilot.”
- If pilot light controls are sticky, do not apply force or use oil.
- Press the red button while simultaneously holding a match to the pilot burner.
Can I relight my own pilot light?
If your pilot light goes out, your furnace will not be able to produce heat because its burners will not ignite. Often, homeowners can relight the pilot themselves.
How long does a thermocouple last on a gas fireplace?
Mainly, the thermocouple lasts for 10 years. But, when it fails, the pilot does not lit up and so the fireplace stops working.
Why is my gas fire pit not staying lit?
Check burner ports and the fuel orifice for blockages and keep them clean. Dirty burner ports can also cause burner backfires so be sure to clear away even the smallest debris. If your gas fire pit lights but doesn’t stay lit, this can also be a result of dirty ports or faulty valves.
What makes a thermocouple go bad?
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.
