I stopped the device. I don't know how to restart it.


Hold in your pilot button, then push the spark button repeatedly to light your pilot. Once its lit, hold that pilot button in for 30 seconds to heat your thermocouple. once its heated, release the button, and slide the slider to burner position. Turn on hot water fixtures to get the unit to light

The pilot won't stay lit on gas hot water tank.


Make sure thermocouple tip is seated inside the burner flame.
Make sure thermocouple is not overtightened. Finger-tight + 1/4 turn.
If the pilot lights, then ECO energy cut off is not tripped, but gas control valve might be bad.
Check color of pilot flame: it should be strong and clear blue.
If pilot flame is weak, or color of flame is yellow-orange: Clean pilot orifice and burner and combustion parts on yearly basis.
Clean air intake screen if applicable.
Increase air supply to water heater. Open a window and see what happens.
Check for adequate draft going up chimney using match under vent hood to see if smoke drafts immediately upwards.
Bleed air out of gas line.
Check gas pressure.

The pilot will light but as soon as the button is released is goes out


1) If water heater has electronic gas control thermostat, then the gas control needs to be tested and possibly replaced. Add a comment and describe electronic gas control.

2) If water heater has non-electronic gas control thermostats, problem sounds like the thermocouple. Problem could also be bad gas control.
Make sure end of thermocouple sits in the pilot flame.

Buy thermocouple at local hardware. They vary by length, for example 18".
Thermocouple screws into bottom of gas control thermostat.
Finger tight plus 1/4 turn. No pipe joint compound or teflon tape on threads.
http://waterheatertimer.org/images/IMG_9146-gas-control-thermo.jpg

Heat from pilot flame travels to gas control thermostat.
Heat is changed into small electric current using a thermistor.
The small current tells gas control that pilot flame is ON, and so gas control keeps gas flowing.
If thermocouple is not working, or has fallen away from pilot flame, the gas control turns off gas to pilot.
This safety device is necessary so gas does not fill up house and cause explosion.

Rheem 22V50F1 pilot won't stay lit. Changed thermo couple & it lit, ran then went out. Let it sit overnight & it lit, ran then went out. What next? p.s. The unit is 5 years old. Thanks


If pilot lights and flame is robust and clear blue, and pilot goes out later, then some suspects can be excluded: air in gas line, low gas pressure, thermocouple is overtightened (finger-tight + 1/4 turn), thermocouple not positioned correctly in the flame, dirty pilot tube.
If flame is yellowish and small: then clean pilot tube and combustion parts.
http://waterheatertimer.org/How-to-install-gas-water-heater.html#clean
Remaining suspects can include: air in gas line, low gas pressure, bad gas control valve, tight house so household vent fans pull air down water heater vent that blows out pilot, hot attic with inadequate ventilation, water dripping down vent.

Pilot light lights but goes out when i turn valve to on


Near the pilot there should be a small metal bulb at the end of what looks like a wire which leads back to the control valve. It's called a thermocouple and it produces a small electrical current when heated. Non-electric heating units have a similar device which does the same job using pressure produced by heating a fluid within the bulb but for our purposes here the difference between the two doesn't matter. The function of the thermocouple is to hold the gas valve open for normal operation of the pilot. If the pilot flame goes out the thermocouple cools and disables the valve so that when the thermostat calls for heat, the gas will not be released if there is no pilot to light the burner. Check to make sure the bulb is being heated by the pilot flame, it may need to be repositioned or the pilot may need to be cleaned of carbon buildup to make it produce an adequate flame. If the thermocouple is close enough to an adequate pilot flame and still you cannot sustain the pilot flame when going from "pilot" to "on" position, the thermocouple is probably the problem so replace it. If the problem still exists, assuming you have already made certain that you have an adequate fuel supply, the problem is in the burner control valve. Changing that is something you should consider leaving to a qualified service person.

Enviro temp hot water heater. 1 week ago pilot out. Able to relight but would go out again once water heated to temp. Replaced thermal couple (tc) with same result. replaced gas therm/valve (t/v). ...


Remove your entire pilot assembly from the heater and gas valve. Remove the aluminum gas line that feeds the pilot assembly. There is a small orifice inside the pilot assembly that may or may not fall out when you take the line off. If it does not fall out remove it and be sure that the very small holes in the top of it are clear. It sounds to me like even though the flame is blue and in contact with the thermo-couple, when the main flame turns off it causes the pilot flame to wave away from the thermo-couple thus shutting it down due to a weak pilot. I have run into this several times and should do the trick.

Model: 21v30-7p, pilot wont stay lit


You need a new thermocouple - or maybe the Pilot flame is not lined up properly to the thermocouple? The thermocouple is a "sensor" that is heated by the flame - which in turn keeps the gas supply to the pilot light on. It the pilot light goes out, then the thermocouple no longer "senses" the heat of the flame, so it turns the gas supply off to the pilot to prevent buildup and explosion.

Why does the pilot light keep going out?


Make sure your pilot flame is hitting the thermocoupler. If not then use air to clean pilot port and try again.

My pilot light will light, but will not stay lit? I have a gas whirpool water heater aprox 1 1/2 years old.Thisis the first time we have encountered any problems with our appliance.


Once the flame has struck it heats up a thermocouple that in turn holds the gas valve open

It is a safety measure in case the flame blows out and the gas keeps on coming.

Sometimes the end of the thermocouple gets dirty and a scrub with a fine emery board does the trick

If not it is a new part (They are not that expensive)

Lighting the pilot light


The steps involved can vary slightly depending on your furnace model and pilot valve type, so if possible try and find the instructions inside the furnace door cover or in the instruction manual. This is for a gas fired furnace, but applies to any gas-fueled appliance including water heater. Two of the most common types of pilot valve body assemblies either have a red reset button and a gas valve or no reset button and a valve knob that can be depressed. But whichever type you've got, if you have an older model furnace with a standing pilot (flame is lit all the time) then this is the basic procedure.
  • Turn you thermostat to 80 degrees or to a setting that will demand heat. Make sure the thermostat is in "Heat" mode.
  • Go to the furnace and find the pilot valve. The pilot valve body is a box shaped device into which the main gas line will run and is located near the gas burners. It will usually have a gas **** or valve knob that reads "On, "Pilot" and "Off." Locate this gas **** or knob.
  • Turn the knob or gas **** to the "Off" position and wait about 3 minutes for any residual gas to clear away.
  • Find the pilot. It's located near the gas burner tube assembly in the furnace.
  • Get your match or lighter ready. Sometimes the pilot is hard to reach. If possible, try and use a long fireplace match when you light it. If you don't have a fireplace match then a butane BBQ grill lighter works well too. If you don't have that, then you can fasten a match to the end of a stick when you light the pilot
  • If you have a pilot with a red Reset button, turn the gas valve from "Off," to "Pilot."
  • If you have a pilot with no red button, turn the knob from "Off" to "Pilot."
  • Place the lit match or ignited lighter tip at the pilot and depress and hold the button or depress the knob as appropriate. Depress the button or knob for about 30 seconds. This maintains gas flow to the pilot until the thermocouple gets hot enough to open the main gas valve.
  • Once the pilot stays lit, slowly release the button or knob and turn the gas **** or knob from the "Pilot" position to the "On" position. This will ignite the burners and keep the flow of gas supplied as required for the burners as called for by the thermostat.
  • If the burners fail to ignite then it may be because the thermocouple did not get hot enough to open the gas valve. Wait a few minutes and then repeat the above procedure. This time hold the red reset button or depress the knob for about 45-60 seconds.
  • Once the main furnace burners ignite, adjust the thermostat to the desired setting.
  • If you've followed the previous steps on lighting the pilot and it still does not light after, or will not stay lit, then you probably have a problem with the thermocouple or an adjustment needs to be made to the pilot. You'll need a furnace service technician to replace or repair these parts. You may find that the pilot lights, but it is an anemic looking flame. That's a different problem we'll look at in the next section.
  • If the pilot lights but the flame is a weak yellow flame, it will not get hot enough to heat the thermocouple to its set point allowing the gas valve to open.
    A natural gas flame should be a bright blue with the tip of the flame having just a tinge of yellow. A propane flame should have a bluish green flame with a tinge of yellow at the tip. The flame should be strong enough to hit the thermocouple tip about 1/2 inch from the tip end. If the flame is weak or shaky looking, check to see that a breeze or draft is not blowing on it. Adjusting the Flame
    There is usually a small screw on the pilot valve body that will adjust the flame. You may have to refer to the manufacturer's instructions to find the screw. Turn the screw as needed to adjust the flame throw. Yellow Flame
    A yellow flame is caused by lack of air and incomplete combustion. It can be caused by a dirty pilot tube tip. Split Flame
    This is caused by dirt in the pilot tube. Take a needle or small nail and gently clean the tube. Flickering or Wavering Flame
    A flame that flickers is usually caused by a draft.
