We have an atwood lp gas water heater 6 gallon g6a7 white rogers control. The pilot lights but when we turn it to on it goes out, even after holding it up to a minute. It was running fine, we thought we...


If pilot stay lit, then thermocouple is working.
If pilot will light, then you have gas. If pilot goes out when pilot button is released, then thermocouple is next suspect.

Thermocouple tip must sit in pilot flame.
The pilot light heat applied to two different metals inside thermocouple causes small current.
The current travels back to gas control valve through copper line.
If the gas valve receive this current, then a magnetic switch stays open and allows gas into the gas control valve.
The magnetic switch is on the end of the red button you push down when lighting pilot. Essentially the red button is an override to the magnetic switch.
If the gas control valve does not receive the current, then the magnetic switch does not stay open when you release the red button.
When replacing thermocouple, note that it is not screwed very tight into the gas control valve. Finger tight + 1/4 turn. If it is overtightened, then the small thermocouple current shorts out against the gas control body.

Hi there. Try cleaning the thermopile, it must be free of soot or any other form of dirt, the pilot flame should be of good quality, as well as the gas pressure.

I have a few issues with an old probably dinosaur Coleman Presidential III 7995a-856 Heating unit. I've had 3 different repairmen look at it and they're clueless. The main pilot will light and stay lit...


if the pilot is clean and and strong then this should play on to the thermocouple , i take it you have changed the thermocouple , and the connection is good at the gas valve , then if this going out could be 1, powerunit on gas valve not holding at thermocouple connection

2. Hole in heatexchanger blowing out pilot when blower comes on

I take it the pilot stays on untill fan comes on and keeps going out , I would think about not putting any more money in to this and get new if sounds as the heater has had its day ,

Pilot will light, goes out when button let go,


A long time ago, in a place far away, I saw an old gas valve, might have been on a water heater, might have been off an A/C unit. I took my 10" adjustable wrench and unscrewed the coil that the thermocouple screws into. Now, when I have the problem that you describe I take the threaded end of the suspected thermocouple and put it into my spare. I light the pilot and hold the button down. Then, after a minute or two, I press the button on my spare, which now has the thermocouple attached. If the spare stays in the "ON" condition, I have just proven my gas valve to have faulted.

I suspect you main gas valve has failed, if you can find another valve, you can test as above, before buying a replacement valve.

Heating isn't working, can't find the red button to relight the pilot


Many times the knob to turn the gas on on the valve is also the pilot knob. Turn it to pilot and hold it down while you light the pilot. Hold it for up to a minute and release. If the pilot stays on then turn it to on. If not you need a new thermocouple.

Pilot light won't stay lit on convection heater.

Pilot light


When you smell gas...is it all the time? If so, this is dangerous. If it only happens when you're trying to start the oven, no problem. Push the red button and hold it while lighting the pilot. Hold for 30 REAL seconds more. Release. The pilot should stay lit. If not, get a service tech.

Unable To Keep Pilot Light Lit!


I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!
