Why does my boiler light keep going off?

A Broken or Faulty Thermocouple

However, if your thermocouple is broken, dirty or misaligned, it may malfunction, shutting off the gas valve and preventing your pilot light from staying lit. If you suspect your thermocouple is at fault, we’d recommend calling out a Gas Safe registered engineer to come and take a look.

What do you do when your boiler light goes out?

If the pilot light has gone out, you’ll need to reset it following your manufacturer’s instructions. Newer boilers will have an ignitor, whereas an older boiler pilot light may require you to light a match for ignition. If you still can’t light your boiler, there could be debris blocking the jet.

Is the pilot light always supposed to be on?

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”.

How do I know if my boiler thermostat is working?

Boiler Thermostat Testing

To confirm that it is most likely a boiler thermostat problem, shut down the system, turn the temperature on your controller down to zero, and do the same with any in-room thermostats if you have them. Turn it on again, but keep your hot water off so you can check the central heating first.

How do I know if my boiler pilot light is out?

The most obvious sign of the failure of a pilot light will be a lack of hot water or warm air since the burner assembly can’t light and do its job of heating these substances. In many systems, a broken pilot light will prevent the appliance from working at all.

Why does the pilot light go off?

A faulty, misaligned, dirty, or damaged thermocouple is often the culprit behind your pilot light going out. The thermocouple is an automatic safety shutoff device that prevents the gas valve from opening if the pilot light is out.

Is it safe if pilot light goes out?

A pilot light may need to be re-lit from time to time after being extinguished on purpose or by accident. If it is accidentally extinguished, there exists a danger that the gas used to keep the flame lit will continue to vent, possibly into the living space.

Can I relight the pilot light by myself?

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.

Is it safe to relight a pilot light?

Most homeowners can relight a pilot light themselves without any issue, but it’s important to be safe when dealing with a gas-powered hot water heater. You should always proceed with care when relighting a pilot light, since the gas used to power your hot water heater is flammable and potentially dangerous.

Can you get carbon monoxide poisoning from a pilot light?

A yellow or orange pilot light will produce carbon monoxide – an odourless, colourless gas that can fill your home and cause carbon monoxide poisoning. Symptoms of this condition include dizziness, headache, fatigue, nausea, unconsciousness, brain damage and death.

How do you light a boiler when the pilot goes out?

Do you smell gas when pilot light goes?

Because it’s a byproduct of combustion, your gas appliances won’t emit any carbon monoxide if a pilot light goes out. They could, however, leak gas, so it’s still important to exercise caution when the pilot light goes out.

Why does my house smell like gas but no leak?

Sulfur is often the cause of a gas smell in homes without gas leaks. It smells identical to the foul rotten odor of gas leaks, but it’s not nearly as harmful in this case. Bacteria found in sewage systems or your kitchen sink release sulfur over time, causing the smell to permeate your home.

Would a carbon monoxide detector detect a gas leak?

Will a carbon monoxide detector detect a gas leak? Technically speaking, a carbon monoxide detector is not designed to detect the presence of gas. Instead, these devices alert for elevated levels of carbon monoxide in the air that could be the result of toxic gases or air quality issues.

How can I tell if there is a natural gas leak in my house?

What does carbon monoxide smell like?

Carbon monoxide gas is colourless and does not smell, so you cannot tell if it is around you. Symptoms of carbon monoxide poisoning include: headache.

What are signs of carbon monoxide in the house?
