Hey Cole are you still there ?
Expert:  cole replied 7 months ago.

ok so thats a newer looking tank you shouldent have to take the face off of it. so there is know spark on these they are electronic ignition. with this type of new valve it should be giving you an error code or blinking light error code. one thing i would do is try and call that american water heater number. if it was older i could walk you through it but try that 1-855 number and they are very good usually. i wish i could help more. do you see an error code.

Customer: replied 7 months ago.
No error code.... It only has a light that would blink and there is no light at all,
Expert:  cole replied 7 months ago.

it could just need a new ignitor but you need to see for sure. american should be able to easily diagnose i would have to be there to run test. ok so if its not giving a blinking code you really need to call them.

if it is under 6 years old they might even send you parts for free.

Expert:  cole replied 7 months ago.

if that number does not get you through try and look up A.O smith tech support they are who make american water heaters.

Expert:  cole replied 7 months ago.

18005271953 is a number i found they claim even after normal business hours.

Expert:  cole replied 7 months ago.

be near the tank when you call. they will want model and most importantly the serial number off the unit.

Customer: replied 7 months ago.
Ok thank u
Expert:  cole replied 7 months ago.

if you have a multi-meter have that handy they may want you to test it.

Expert:  cole replied 7 months ago.

I hope they get you fixed up. Have a good holiday. wish it was a little older so i could walk you through it better.

Well I got the pilot to light but won't stay lit. So need to check the voltage to the Cupler
Customer: replied 7 months ago.
fortunately I don't have a multimeter
Customer: replied 7 months ago.
Either way it won't stay lit what else could I do see that the switch or the whole burner
Expert:  cole replied 6 months ago.

Usually its the thermal couple not often does a new gas valve go out. the thermal couple activates the gas valve to open so if your pilot is lit and not opening the gas valve its usually a cheap try to replace thermal couple.
