Michael,
The thermocouple sensor may not be in the best position to sense that the pilot is lit.
Adjust the thermocouple mount or simply bend the thermocouple "wire" so that the pilot flame is touching the tip.

Your on right track. When this happens and small flame still there, pull wire(s) off at gas valve, or test for voltage from ECO to gas valve. No voltage, then there should be no gas. Change gas valve.

Testimonial: "Changed the gas valve, now heater works as it should, No fumes and no flame after shutoff."

I would definitely have the burner tube cleaned and adjusted if necessary. Sounds like a possible spider web in the tube, as well as have heat chamber blown out with compressed air if at all possible to remove soot build up. Stand back when blowing it out, or you"ll be covered in soot.
You can buy a long brush for cleaning barbecue burners, that work well.

You are correct, there should be no flame after it shuts off. Pull the + wire off at contacts as well and see if flame remains, if it does, the gas valve is faulty (leaking by) and should be replaced.

The yellow is caused because the flame does not have enough oxygen. Per your explanation that is being caused because the exaust is not working. Fix the exaust problem and it probably will begin opperating properly.

You may have instant hots for the sinks, a small heater for each location which won't be on the tub. If there is a flame fail the hot water heater is not working. Check the flame sensor and ignitor.

I have a new Atwood G6A-7 water heater. The pilot lights fine but gas flow, when it turns on, is so strong it will blow the pilot out. Certain times, it sounds and looks like a mini fire ball going


Clean burner tube with proper brush, such as long spring type for bar-b-Q burner tube that are available at most hardware stores, and make sure you have new burner tube aligned properly (straight on) with brass orifice on gas control. Then be sure to adjust air shutter for nice blue flame, with little orange at tip. Do not give so much air that flame roars or jumps off the end of the burner tube. Too many people think more air, less fuel, but actually, when flame roaring and jumping off end of tube, the heat passes through faster and it takes longer to heat the water inside the tank. Like I said, only enough air to have quiet, steady blue flame. If your not giving it enough air, you'll see dark soot on trailer above water heater, which indicates burning too rich, need more air, or perhaps pilot is partially plugged. Pilot flame should also be blue, not yellow/orange. Small air intake hole on side of fitting just before pilot tube can get spider web, or debris in it as well. Use air to blow that out or a piece of wire like a paper-clip to clean inside that hole.

My gas water heater pilot light will not stay lit


Hi Mike,
1stly you have to understand what the pilot light does!
Yes, it lights the flame, but it protects you from gassing yourself!
that is thye main job!
hava a look inside!
In front of the pilot flame, (it might have a double flame... (one flame on the bottom & another on top.) is a curved piece of metal plate. The flame is supposed to heat that plate untill it it very hot! Thenm the plate bends down as it is a bimetyaalivc strip!
This opens the bsaety valve & you can let go.
The flame will noe stay on. If a gush of wind blows the flame out, the strip will cool & the safety valve close, preventing a dead family in the morning.
There is a newer system as well.
Right in front of the flame, is a pointed sensor with it's tip in the flame. . It has a electric cable running to a safety valve. This sensor have to heat up as well. It is a heat battery that activates the valve. See that it did not move!
If it heats up, & the valve does not keep the pilot flame going after a few seconds, the unit has to be replaced!
Safety first!
Andy

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.

Pilot is not heating thermalcoupler


You may have a dirty pilot orifice. Try this. Turn off the pilot by turning the control knob to off. Remove the front panel to get access to the pilot orifice. Use a can of compressed air with attached straw (the same stuff you use to clean computer keyboards) and blow out the pilot orifice, which is inside the pilot assembly where the pilot flame burns. Blow it out from the top and from the sides through the air holes. Then relight the pilot and see if that improves the flame size and color (blue) to heat the thermocouple. Douglas

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.
