Water Heater - Pilot Will Not Stay On
I have a 6 gallon atwood water heater ( model G6A-7 ) and the pilot light will not say lit. If I hold the control valve in the pilot position it does light but after 30 second to a minute or more it...

Since the thermocouple/pilot light assembly is new and if the flame is making good contact with the thermocouple that leaves only one thing and that is the gas valve has gone bad.
YEP.......
Pilot flame heating thermocouple...thermocouple connection tight....millivolt signal from thermocouple energizes magnet which allows gas to flow thru MAIN
You can do an easy test on thermocouple.
Disconnect it from gas control. Attach multimeter clip to end/other clip to tubing and then heat thermocouple with lighter. 12 millivots..good.
Weak magnet.....won't stay open
ECO Probe (high temp t-stat) blown...one shot device. Too high water temp or too HIGH of pilot flame (190*F) no millivolt signal completed circuit
Either case.........new gas control
