Can you post a picture of the gas control valve here? click on ADD FILES next to the SEND button to post a pic
One other thing, the GP series is not power vented. Do you have an aftermarket power venter? If so what brand is the power venter?
The specs I see for the GP series show no power vent. I need pictures especially since what you're telling me doesn't align with my research.
Thanks for the pictures but they don't help. I need a wider shot showing the entire gas control valve and another showing the top of the heater.
How many times does the LED blink before it pauses then repeats?
Please answer my last question
Fast or slow flash? is the fan on the top of the unit running?
If the fan is running but nothing else happens then you could have a bad gas valve. You should be getting an error sequence on the LED not a steady flash, no pause. Check all your electrical connections.
Then you have a bad gas control valve. What you did yesterday probably had no impact on this at all except that you turned off the power to the unit.
I hate to be the bearer of bad news but the most cost effective option will probably be to replace the water heater. It looks like your unit is at least 10 years old which is about as long as they last before the tank could leak at any time. It's probably not worth the expense to replace the gas valve assuming you can even find this obsolete valve.
The gas valve is obsolete. I don't know if it's even still available. If my memory is accurate this model went out of production 10 years ago. I can confirm this if you can give me a serial number. You could call in a pro and have them check this out but I'm not optimistic about finding a replacement valve.
Sorry for the typo I need the serial number to check the age of the unit
Ok, that may extend the life of the tank somewhat but finding a gas valve replacement will still be a challenge. You'll have to cal in a pro in any event unless you want to replace the heater yourself.
Do you have any more questions?
