Why did my water heater pilot light go out?

Pilot lights can go out for several reasons, including: A leak – If your pilot light flame burns yellow rather than bright blue, it means that not enough gas is getting to the burner – often the sign of a leak somewhere in the system.

Is it dangerous if the pilot light goes out on water heater?

Is it Dangerous if the Water Heater’s Pilot Light Goes Out? In most cases, it isn’t dangerous when the water heater pilot light is extinguished. This is because modern gas-fueled water heaters feature valves that automatically close the supply of gas when the pilot light goes out.

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

Most furnaces with electronic ignition have a device called a hot surface igniter. The difference is that the flame is only lit (by an electronic spark) when your furnace is ready for a heating cycle. When the pilot light is not needed, it is completely off, saving you money on gas.

Does gas still flow when pilot light goes out?

If your pilot light repeatedly goes out, this is a likely culprit. If this flame sensor should fail, gas will continue to flow even after the pilot light has been extinguished, causing a safety hazard, and requiring immediate repair.

Can I leave my water heater on pilot?

3 Answers. Yes it is safe to leave the water heater in pilot mode while flushing. You do not want the burner to fire while the tank is empty as this can damage the tank but the pilot will not cause a problem. Added: most gas valves with a standing pilot have the temp setting and “pilot” then off settings.

What do I do if my water heater won’t light?

If you have a natural or propane gas water heater, chances are the pilot has gone out. If the pilot doesn’t relight, if it goes out right after lighting or if it goes out repeatedly, by far the most common cause is a bad thermocouple.

How do you fix a propane heater that won’t stay lit?

Propane Heaters – When They Don’t Stay Lit

If the thermocouple is too far from the flame, this can cause the pilot to go out and shut down the propane heater; you can fix this easily by moving the thermocouple closer to the flame.
The thermocouple could also be worn out, in which case it needs to be replaced.

Why does my light switch get hot when I turn it on?

When this happens, a small spark on the electrical contacts will be emitted whenever you turn the light on and off. Soon the contacts won’t meet properly, and electricity will flow more freely, creating heat. Again, this is a fire risk.

Why is the pilot light on my patio heater not working?

Spider webs in the pilot tube and a faulty tilt switch can be two reasons why an outdoor patio heater pilot light won’t start or stay lit. The repair of both is discussed.

Is it normal for a dimmer switch to get warm?

Dimmer switches get warm, and this is normal. This is part of the function of these switches. As they dissipate the electricity to brighten or dim the lights, they will get warm. If you think they are getting too warm, you need to call for service and inspection. It is possible to have the first three problems with a dimmer switch.

Why does the pilot light go out on my water heater?

A thermocouple is a device that senses the heat of a pilot and lets the gas flow to the burner. If the thermocouple is malfunctioning, it doesn’t allow the gas to run through the pilot and the burner. In return, the pilot light goes out repeatedly and would not stay lit.
