I have a State Industries PR640NOLS water heater using a 37C73U 640 gas valve
The pilot lights up. Only takes about 5 seconds for it to stick.
The flame and pilot on this unit shuts off randomly. I have seen it go off after about 1 minute, and another time is was on for > 30 minutes
I tried turning the control to full, and then down to low, and the pilot remained on.
We recently purchased the house, so I don't have any history on this heaters behavior.
As a quick fix, since I already had the burner out, I did replace the thermal coupling, but no help.
Next step is to replace the gas valve, but I want to check first if there was something else I needed to do
Thanks

If this is a propane unit, check your inlet pressure.
Check for obstruction in the pilot tube. Make sure everything is nice and clean.

First, do no harm.

this is Natural Gas, not propane
I took the burner assy out and it was clean. I also confirmed no issues with exhaust.
My new gas valve will arrive today and I will install tomorrow. Hopefully that will resolve the issue
