Yes, it can be dangerous if the pilot light goes out on a furnace because it can lead to a buildup of gas, which can pose a risk of fire or explosion. It is important to follow safety procedures and relight the pilot light promptly if it goes out.
If the pilot light goes out on a furnace, the furnace will not be able to ignite and produce heat. To relight the pilot light, you can follow the manufacturer's instructions provided in the furnace manual. Typically, this involves turning off the gas supply, waiting for the gas to dissipate, and then using a long lighter or match to relight the pilot light.
A thermocouple in a gas furnace is a safety device that detects if the pilot light is on. If the pilot light goes out, the thermocouple shuts off the gas supply to prevent a dangerous gas leak. This helps ensure the furnace operates safely and efficiently by preventing the buildup of gas without ignition.
When pilot light goes out, gas flows out of the pilot light nozzle. If out has continued for a long time, a gas cloud can develop around the furnace. When you go to light the pilot light, you'll ignite this gas cloud and make a big fire ball. If your basement is drafty, you might never get a huge cloud of gas hovering around your furnace. When you notice that your pilot light is out, you should shut off the gas to the furnace and allow any stray gas to dissipate before you turn the gas back on and light the pilot light. alliedallcityinc.com
You may not always smell gas if the pilot light on your furnace is out. It's important to check for other signs such as a lack of heat or a clicking sound when the furnace tries to ignite. If you suspect a gas leak, it's best to evacuate the area and contact your gas company immediately.
A gas furnace pilot flame stays burning by receiving a constant flow of gas from the pilot light assembly. The pilot light assembly contains a thermocouple that detects the presence of the pilot flame. If the flame goes out, the thermocouple signals the gas valve to shut off, preventing any gas leaks.
so when the pilot goes out the gas valve is shut off
A thermocouple in a gas heater is a safety device that detects if the pilot light is on. If the pilot light goes out, the thermocouple shuts off the gas supply to prevent a dangerous gas leak.
Turn the knob on the top of the gas valve to "Pilot" and hold it down. Put your match or lighter near the pilot and it should light. Continue holding the knob down for about 30 seconds then release, and the pilot should stay lit. If it goes out then you may need to replace the thermocouple (the gold color rod that the pilot flame burns on) or have the pilot cleaned if it has a yellow flame.
A heater thermocouple is a safety device that detects if the pilot light in a heating system is lit. If the pilot light goes out, the thermocouple shuts off the gas supply to prevent a dangerous gas leak.
At pilot light, where pilot light flame goes directly onto thermo coupler.
No, it is not dangerous. (Unless you are working with a water heater that is 20+ years old.) In any modern hot water heater, if the pilot light goes out a fail-safe will go off - preventing gas from leaking out. Also, there is a sensor so if there is not enough air-flow or oxygen with the water heater, it will shut off the gas.
The pilot light goes out when the gas appliance is turned to the "on" position because the flow of gas is redirected from the pilot light to the main burner, causing the pilot light to extinguish.
