Question about Water Water Heaters

I have an Atwood hot water heater with a 37c14u-5 controller. I can get cold water but no hot water, there is no flame. Do I need to replace the whole unit or just the thermocouple?

Try removing the thermocouple where it attaches to gas control, and spray a little WD-40 in the hole, then spin a rolled up small piece of steel wool in the hole as well, then blow it out with compressed air if you can. Then reconnect thermocouple. Make sure thermocouple tip is getting good flame under it, and if that doesn't cure it, then it's time to replace gas control.

Did you make sure the connection between the thermocouple and the control is tight and that the tip of the thermocouple is in the flame?

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."

Make sure flame is good under thermocouple probe so that it gets proper sensing of flame, and if that's o.k., before you change gas control, remove thermocouple fitting where it attaches to gas control and spray wd-40 in the hole and twirl up some steel wool and push it in the hole and twirl it to try and clean the surface inside there as well. Then spray it out with WD-40 once more to flush out shavings etc, and if you have compressed air, blow it out as well. Now re-attach fitting and snug it, then re-try pilot again. If it works, great if not replace gas control. Let me know the results. You do realize that it should be a certified technician who changes that gas control if necessary, correct?

Atwood water heater g6a8e lights but flame goes out after 5 to 10 seconds. I replaced igniter / thermocouple and it worked for a while but problem is back. So I need to replace circuit board?


Make sure you pull connector off and clean it and contacts on board. Be sure igniter is in flame good too. Does it have the thermal cut off in-line? Its the little resistor looking piece inside the plastic cover. If it does, and still running a few seconds and going out, remove it from the circuit, and connect wire end to where you removed cut out from, thus eliminating it from the circuit, and test it. If that cures it, replace that cut-out, as it is a safety device in case of flame up, it cuts gas off to prevent fire. Just leave it out long enough to test it.

Leaking propane is red flag #1 and fire hazard.
Immediately update your insurance and then turn off gas.
If pilot is not staying lit, then gas leak can be cause of pilot problem since pressure on the line is reduced.
Other causes include bad gas control valve, air in the gas line, bad thermocouple, burner parts need cleaning, or all the above.
After fixing leak, replace thermocouple, clean combustion chamber and burner parts, and bleed gas line to remove air.

Have you checked back of water heater for proper valve positioning? (by-pass may be on)
Cold water enters through bottom fitting and hot comes out the top. Any valves in between should be closed and any valves going in bottom and out top should be open.
