I have a Samsung gas stove that is probably 5 years old. Today, the oven stopped working. The top burners work fine, the oven and Brodie’s not work. I have verified that the igniter works, they glow cherry red, but there is no gas delivered.
I suspect the gas safety valve, and I’m looking for a way to test that hypothesis. Any info would be greatly appreciated.

Does the broil function work? It's likely your oven igniter is weak. They will glow but if there isn't enough resistance the valve won't open. If the broil function works and you have no other option, you could try to swap the igniter till you can get a replacement, they are very easily broken so be careful.
Neither the broil or oven function works.
Do you have a model number? It's rare for the gas valves to fail. It may be both igniters failed
NX58J5600SG while not impossible, I find it highly improbable that both igniters would go at the same time. Particularly the broiler, as it’s rarely used, I’m talking maybe 20 times total since the stove was new.
Check your gas valve and see if the tab has been tripped
If it glows a cherry red it likely is not hot enough to ignite the gas so the valve does not open. They are easy to replace if you are somewhat handy. Hope thats all it is.
If it’s a thermistor, any idea what the resistance values should be for a working igniter? I could check it with a meter and possibly spoof it to see if the valve will open.
thermistor, any idea what the resistance value
To me, the mystery deepens. Resistance values appear to check out on both the broil and bake HSI. Cold, it's just under 200 ohms, fully lit up it brings it down to 37 ohms, and that's consistent with both HSIs. Put the clamp meter on the broiler, 3.3 amps, just as it's supposed to be, put the clamp meter on the broil lead at the safety valve, 3.3 amps. That one appears to be good. Put the clamp meter on the bake HSI, 2.86 amps. Okay, that's below what it should be pulling, likewise the meter on the safety valve for the bake side shows 2.86. Okay, I'll accept that I have a bad HSI for the bake side of things. But now, there's another mystery, why doesn't the broiler work? I would expect gas to flow and ignite with the values I"m seeing.
Hope this helps. Check the amp draw of the igniter. Less than 3.3 and it's no good. Verify that it's receiving 120V also.

That is going to be very helpful. Once I finish the Xmas prep, I’ll break out the clamp meter.
