Try replacing the pilot generator which is in the pilot assembly. It is the piece with a silver cable coming out of it and that cable splits open into a red and white wire at the gas valve, That piece holds the valve open once it is hot enough and is likely not putting out enough voltage to do its job.

Pilot goes off as soon as I release the button


You need to hold the button down for about 3 mins. If it goes out after that long the thermocouple is probably bad. Look at how long the wire is from the pilot light to the gas valve. They come in different lengths.

When I press down and turn the know the pilot lights but as soon as you let up on the knob to turn it there is a click and the pilot light goes out.. This is on my Mr. Heater Big Buddy


When the pilot lights continue holding the button down for a full minute and then release. It should stay lit then to allow you to turn it to the on position. If the pilot will not stay lit after holding it for the full minute, then the thermocouple will need to be replaced.
Hope this helps.

My pilot light went out and when I try to relight it, the flame will light when I press down on the red button by the gas control valve. I hold it down for about a minute like the instructions say but when...


Hi you will need to replace the thermocouple. This is the copper tube that screws in to the gas valve and goes back and mounts along side of the pilot. Most will pull straight out. When they go out, the pilot will light when you hold the red button down, but as soon as you release it off it goes. You can but this thermocouple at any hardware store. They come in different lengths, But I would get a 36" one. They will coil up so they wont be in the way. Its better to have a longer one then one that's to short. Make sure the tip is in the flame, or it will do the same thing. It has to get very hot to keep and produce milivolts to keep it on.Please don't forget to rate me on this as I know you will be kind. This will solve your problem for sure.

I cant get the pilot lit...I turn it to pilot...hold down the button and light the pilot..but when I let it go to turn it to "on" the flame goes out.


Are you holding the button down for a minute or so after you light the pilot before releasing the button?

If so, almost certainly, your thermocouple is bad. This is the long tube which runs from the control box to the pilot flame. Remove this tube, take it to the hardware store and get an exact replacement.

Once the thermocouple is replaced, your pilot light should stay on.

We dont think our cylinder is on we have just moved in and have no hot water


The question is? I'll assume you cylinder is the water heater, right?
On the heater (water) you will find or see the red controls and a sheet metal cover over a hole. Remove the cover and this is where you light the pilot light. Press down on the red dial and turn it to pilot. In that position you will be able to press the red button . Geyt a long match or bbq lighter, then, holding down the red button dow for a minute or so and place a match or lighter into yhe area where the lines go The flame will catch the gas and lite the pilot if yo simply move your glame around. When the flame catch on the pilot, continue holding the button down for sveral minutes until the buld the flame isheating gets hot. Then release the buton and turn the main dial to on. The main burner should fire up. If not, and the pilot goes out, repeat the process. The bulb in the pilot flame is a thermocoupler that shuts all gas off if it doesn't detect a pilot flame, so hold the button down longer. If the pilot goes out when you release the button, The thermocoupler is no good and needs replacing. Good Luck_Ned_

Pilot wont light


If the pilot light goes out when you release the primer,then the thermocouple is bad.You can try to adjust the thermocouple,if it can be.It needs to be in the pilot flame.If the thermocouple is not in the flame,it will not stay lit.If you can not get the pilot to light at all,with the primer pushed down,then replace the regulator.To light the pilot light,you need to turn the dial to pilot.Then press the primer button down and hold it.The primer is either built into the turn knob,or it is a res button.Hold the primer down,and light the pilot,continue holding the primer down for at least 40 seconds.Then release the primer slowly,and if the pilot light starts to get weak,and try to go out,then push back down,and hold 30 seconds more.After the pilot stays lit,turn the knob to furnace or low,or whatever the directions say.

The pilot light will not stay lit to light the heater.


The power pile (pilot generator) is defective. It produces a milivolt signal to ensure to keep the gas valve open. If it goes bad, the valve thinks the pilot is out, even when you are holding the button down, so when you release the button, it shuts the gas off to prevent excess gas buildup and a possible explosion.

I need to know how to light the pilot on my somewhat old water heater. The model is called the challenger 5 the model number 153.331471


On these older gas water heaters there is a gas control with temperature selection and below that is a removable cover. Once you remove the cover you can gain access to the pilot. You must rotate the knob on the top of the control to the pilot position. When in the pilot position, hold the red button down and light the pilot. Continue to hold the button down after the pilot is lit for about one minute. If when you release the red button the pilot goes out, try one more time. If it goes out again after releasing the button your thermocouple is bad and must be replaced. The thermocouple generates a millivolt electrical current that hold the gas valve in the operating condition when the pilot is lit. When the pilot goes out there is no heat to generate this small electrical field.
